這篇文章主要講解了“SpringCloud的spring-security怎么配置”，文中的講解內容簡單清晰，易于學習與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學習“SpringCloud的spring-security怎么配置”吧！

一、簡介

Web應用的安全管理，主要包括兩個方面的內容：身份認證、用戶授權，此處使用spring-cloud-security來說明。

二、依賴管理

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-security</artifactId>
</dependency>
<dependency>
   <groupId>org.thymeleaf.extras</groupId>
   <artifactId>thymeleaf-extras-springsecurity4</artifactId>
</dependency>

三、安全策略配置

Spring Security已經大體實現了，我們這里只是需要一些配置與引用。

package com.example.demo.config;

import com.example.demo.utils.security.CustomUserService;

import com.example.demo.utils.security.LoginSuccessHandler;

import com.example.demo.utils.security.MyFilterSecurityInterceptor;

import com.example.demo.utils.security.SecuritySettings;

import org.apache.commons.lang3.StringUtils;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;

import org.springframework.security.config.annotation.web.builders.WebSecurity;

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.web.access.intercept.FilterSecurityInterceptor;

import org.springframework.security.web.authentication.AuthenticationSuccessHandler;

import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

/**

* Security安全配置

*

* @Author: 我愛大金子

* @Description: Security安全配置

* @Date: Create in 15:20 2017/7/5

*/

@Configuration

@EnableWebSecurity

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired

private CustomFilterSecurityInterceptor customFilterSecurityInterceptor; // 權限管理過濾器

@Autowired

private SecuritySettings securitySettings; // 自定義安全配置類

/**注冊UserDetailsService的bean*/

@Bean

public UserDetailsService customUserService(){

return new CustomUserService();

}

/**登錄認證*/

@Override

protected void configure(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(customUserService()); //userDetailsService驗證

}

/***設置不攔截規則*/

@Override

public void configure(WebSecurity web) throws Exception {

web.ignoring().antMatchers("/js/**", "/css/**", "/images/**", "/druid/**");

}

/**安全策略配置*/

@Override

protected void configure(HttpSecurity http) throws Exception {

// 設置游客可以訪問的URI

if (StringUtils.isNotBlank(securitySettings.getPermitall())) {

http.authorizeRequests().antMatchers(securitySettings.getPermitall().split(",")).permitAll();

}

http.authorizeRequests()

.anyRequest().authenticated() //任何請求,登錄后可以訪問

// 配置登錄URI、登錄失敗跳轉URI與登錄成功后默認跳轉URI

.and().formLogin().loginPage("/login").failureUrl("/login?error").permitAll().defaultSuccessUrl("/", true).successHandler(loginSuccessHandler())

// 注銷行為任意訪問

.and().logout().permitAll()

// 設置拒絕訪問的提示URI

.and().exceptionHandling().accessDeniedPage("/login?illegal")

;

http.addFilterBefore(myFilterSecurityInterceptor, FilterSecurityInterceptor.class);

}

/**登錄成功處理器*/

private AuthenticationSuccessHandler loginSuccessHandler() {

return new LoginSuccessHandler();

}

說明：

loginPage：設置一個實驗自定義的登錄URI

loginSuccessHandler：設置自定義的登錄處理器

permitAll：是允許訪問

accessDeniedPage：配置拒絕訪問的提示URI

antMatchers：對URI的配置

了解springcloud架構可以加求求：三五三六二四七二五九

假設我要管理員才可以訪問admin文件夾下的內容，如：.antMatchers("/admin/**").hasRole("ROLE_ADMIN")，

也可以設置admin文件夾下的文件可以有多個角色來訪問，如：.antMatchers("/admin/**").hasAnyRole("ROLE_ADMIN","ROLE_USER")

也可以通過hasIpAddress來指定某一個ip可以訪問該資源,寫法如下.antMatchers("/admin/**").hasIpAddress("210.210.210.210")

3.1、自定義安全配置類

為是更方便的使用springSecurity，我們自定義一個權限的配置類，如配置登錄的URI、游客訪問的URI等配置項

package com.example.demo.utils.security;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.context.annotation.Configuration;

/**

* 自定義安全配置類

*

* @Author: 我愛大金子

* @Description: 自定義安全配置類

* @Date: Create in 9:45 2017/7/6

*/

@Configuration

@ConfigurationProperties(prefix = "securityConfig")

public class SecuritySettings {

/**允許訪問的URL，多個用逗號分隔*/

private String permitall;

public String getPermitall() {

return permitall;

}

public void setPermitall(String permitall) {

this.permitall = permitall;

}

3.2、登錄成功處理器

登錄成功后，如果需要對用戶的行為做一些記錄或者執行其它操作，則可以使用登錄成功處理器。

package com.example.demo.utils.security;

import com.example.demo.pojo.SysUser;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.userdetails.User;

import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

/**

* 登錄成功處理器

*

* @Author: 我愛大金子

* @Description: 登錄成功處理器

* @Date: Create in 11:35 2017/7/6

*/

public class LoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {

@Override

public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {

User userDetails = (User) authentication.getPrincipal();

System.out.println("登錄用戶：username=" + userDetails.getUsername() + ", uri=" + request.getContextPath());

super.onAuthenticationSuccess(request, response, authentication);

}

3.3、springMVC 配置（訪問 /login 轉向 login.html 頁面）

package com.example.demo.config;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**

* springMVC 配置（注冊訪問 /login 轉向 login.html 頁面）

*

* @Author: 我愛大金子

* @Description: springMVC 配置（注冊訪問 /login 轉向 login.html 頁面）

* @Date: Create in 16:24 2017/7/5

*/

@Configuration

public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override

public void addViewControllers(ViewControllerRegistry registry) {

registry.addViewController("/login").setViewName("login");

}

四、登錄認證

在安全策略配置代碼中有，主要看自定義的CustomUserService，此類實現了UserDetailsService接口，重寫了loadUserByUsername方法

package com.example.demo.utils.security;

import com.example.demo.dao.SysPermissionDao;

import com.example.demo.dao.SysUserDao;

import com.example.demo.pojo.SysPermission;

import org.springframework.security.core.userdetails.User;

import com.example.demo.pojo.SysUser;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.core.GrantedAuthority;

import org.springframework.security.core.authority.SimpleGrantedAuthority;

import org.springframework.security.core.userdetails.UserDetails;

import org.springframework.security.core.userdetails.UserDetailsService;

import org.springframework.security.core.userdetails.UsernameNotFoundException;

import java.util.ArrayList;

import java.util.List;

/**

* 自定義UserDetailsService,將用戶權限交給springsecurity進行管控

*

* @Author: 我愛大金子

* @Description: 將用戶權限交給Springsecurity進行管控

* @Date: Create in 16:19 2017/7/5

*/

public class CustomUserService implements UserDetailsService {

@Autowired

private SysUserDao sysUserDao;

@Autowired

private SysPermissionDao sysPermissionDao;

@Override

public UserDetails loadUserByUsername(String username) {

SysUser user = sysUserDao.findByUserName(username);

if (user != null) {

List<SysPermission> permissions = sysPermissionDao.findByAdminUserId(user.getId());

List<GrantedAuthority> grantedAuthorities = new ArrayList <>();

for (SysPermission permission : permissions) {

if (permission != null && permission.getName()!=null) {

GrantedAuthority grantedAuthority = new SimpleGrantedAuthority(permission.getName());

//1：此處將權限信息添加到 GrantedAuthority 對象中，在后面進行全權限驗證時會使用GrantedAuthority 對象。

grantedAuthorities.add(grantedAuthority);

}

return new User(user.getUsername(), user.getPassword(), grantedAuthorities);

} else {

throw new UsernameNotFoundException("admin: " + username + " do not exist!");

}

五、權限管理

在Security安全配置類中使用了權限管理過濾器CustomFilterSecurityInterceptor

package com.example.demo.utils.security;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.access.SecurityMetadataSource;

import org.springframework.security.access.intercept.AbstractSecurityInterceptor;

import org.springframework.security.access.intercept.InterceptorStatusToken;

import org.springframework.security.web.FilterInvocation;

import org.springframework.stereotype.Service;

import java.io.IOException;

/**

* 權限管理過濾器

*

* @Author: 我愛大金子

* @Description: 權限管理過濾器

* @Date: Create in 17:16 2017/7/5

*/

@Service

public class CustomFilterSecurityInterceptor extends AbstractSecurityInterceptor implements Filter {

@Autowired

private CustomFilterInvocationSecurityMetadataSource customFilterInvocationSecurityMetadataSource; // 權限配置資源管理器

/**權限管理決斷器*/

@Autowired

public void setMyAccessDecisionManager(CustomAccessDecisionManager customAccessDecisionManager) {

super.setAccessDecisionManager(customAccessDecisionManager);

}

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

FilterInvocation fi = new FilterInvocation(request, response, chain);

invoke(fi);

}

public void invoke(FilterInvocation fi) throws IOException, ServletException {

//fi里面有一個被攔截的url

//里面調用MyInvocationSecurityMetadataSource的getAttributes(Object object)這個方法獲取fi對應的所有權限

//再調用MyAccessDecisionManager的decide方法來校驗用戶的權限是否足夠

InterceptorStatusToken token = super.beforeInvocation(fi);

try {

//執行下一個攔截器

fi.getChain().doFilter(fi.getRequest(), fi.getResponse());

} finally {

super.afterInvocation(token, null);

}

@Override

public void destroy() {

}

@Override

public Class<?> getSecureObjectClass() {

return FilterInvocation.class;

}

@Override

public SecurityMetadataSource obtainSecurityMetadataSource() {

return this.customFilterInvocationSecurityMetadataSource;

}

說明：

customFilterSecurityInterceptor：權限管理過濾器

customAccessDecisionManager：權限管理決斷器

customFilterInvocationSecurityMetadataSource：權限配置資源管理器

其中過濾器在系統啟動時開始工作，并同時導入權限配置資源管理器和權限管理決斷器，對用戶訪問的資源進行管理。權限管理決斷器對用戶訪問的資源與用戶擁有的角色權限進行對比，以此來判斷用戶是否對某個資源具有訪問權限。

5.1、權限管理過濾器

繼承與AbstractSecurityInterceptor，實時監控用戶的行為，防止用戶訪問未被授權的資源。

package com.example.demo.utils.security;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.access.SecurityMetadataSource;

import org.springframework.security.access.intercept.AbstractSecurityInterceptor;

import org.springframework.security.access.intercept.InterceptorStatusToken;

import org.springframework.security.web.FilterInvocation;

import org.springframework.stereotype.Service;

import java.io.IOException;

/**

* 權限管理過濾器

*

* @Author: 我愛大金子

* @Description: 權限管理過濾器

* @Date: Create in 17:16 2017/7/5

*/

@Service

public class CustomFilterSecurityInterceptor extends AbstractSecurityInterceptor implements Filter {

Logger log = LoggerFactory.getLogger(CustomFilterSecurityInterceptor.class);

@Autowired

private CustomFilterInvocationSecurityMetadataSource customFilterInvocationSecurityMetadataSource; // 權限配置資源管理器

/**權限管理決斷器*/

@Autowired

public void setMyAccessDecisionManager(CustomAccessDecisionManager customAccessDecisionManager) {

super.setAccessDecisionManager(customAccessDecisionManager);

}

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

FilterInvocation fi = new FilterInvocation(request, response, chain);

log.info("【權限管理過濾器】請求URL：" + fi.getRequestUrl());

invoke(fi);

}

public void invoke(FilterInvocation fi) throws IOException, ServletException {

//fi里面有一個被攔截的url

//里面調用CustomFilterInvocationSecurityMetadataSource的getAttributes(Object object)這個方法獲取fi對應的所有權限

//再調用CustomAccessDecisionManager的decide方法來校驗用戶的權限是否足夠

InterceptorStatusToken token = super.beforeInvocation(fi);

try {

//執行下一個攔截器

fi.getChain().doFilter(fi.getRequest(), fi.getResponse());

} catch(Exception e) {

log.error("【權限管理過濾器】【異常】" + e.getMessage(), e);

} finally {

super.afterInvocation(token, null);

}

@Override

public void destroy() {

}

@Override

public Class<?> getSecureObjectClass() {

return FilterInvocation.class;

}

@Override

public SecurityMetadataSource obtainSecurityMetadataSource() {

return this.customFilterInvocationSecurityMetadataSource;

}

5.2、權限管理決斷器

權限管理的關鍵部分就是決斷器，它實現了AccessDecisionManager，重寫了decide方法，使用自定義的決斷器，在用戶訪問受保護的資源時，決斷器判斷用戶擁有的角色中是否對改資源具有訪問權限，如果沒有，則拒絕訪問

package com.example.demo.utils.security;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.security.access.AccessDecisionManager;

import org.springframework.security.access.AccessDeniedException;

import org.springframework.security.access.ConfigAttribute;

import org.springframework.security.authentication.InsufficientAuthenticationException;

import org.springframework.security.core.Authentication;

import org.springframework.security.core.GrantedAuthority;

import org.springframework.stereotype.Service;

import java.util.Collection;

import java.util.Iterator;

/**

* 權限管理決斷器

*

* @Author: 我愛大金子

* @Description: 權限管理決斷器

* @Date: Create in 17:15 2017/7/5

*/

@Service

public class CustomAccessDecisionManager implements AccessDecisionManager {

Logger log = LoggerFactory.getLogger(CustomAccessDecisionManager.class);

// decide 方法是判定是否擁有權限的決策方法，

//authentication 是釋CustomUserService中循環添加到 GrantedAuthority 對象中的權限信息集合.

//object 包含客戶端發起的請求的requset信息，可轉換為 HttpServletRequest request = ((FilterInvocation) object).getHttpRequest();

//configAttributes 為MyInvocationSecurityMetadataSource的getAttributes(Object object)這個方法返回的結果，此方法是為了判定用戶請求的url 是否在權限表中，如果在權限表中，則返回給 decide 方法，用來判定用戶是否有此權限。如果不在權限表中則放行。

@Override

public void decide(Authentication authentication, Object object, Collection<ConfigAttribute> configAttributes) throws AccessDeniedException, InsufficientAuthenticationException {

if(null== configAttributes || configAttributes.size() <=0) {

return;

}

ConfigAttribute c;

String needRole;

for(Iterator<ConfigAttribute> iter = configAttributes.iterator(); iter.hasNext(); ) {

c = iter.next();

needRole = c.getAttribute();

for(GrantedAuthority ga : authentication.getAuthorities()) {//authentication 為在注釋1 中循環添加到 GrantedAuthority 對象中的權限信息集合

if(needRole.trim().equals(ga.getAuthority())) {

return;

}

log.info("【權限管理決斷器】需要role:" + needRole);

}

throw new AccessDeniedException("Access is denied");

}

@Override

public boolean supports(ConfigAttribute attribute) {

return true;

}

@Override

public boolean supports(Class<?> clazz) {

return true;

}

5.3、權限配置資源管理器

權限配置資源管理器實現了FilterInvocationSecurityMetadataSource，在啟動時就去加載了所有的權限列表，權限配置資源管理器為決斷器實時提供支持，判斷用戶訪問的資源是否在受保護的范圍之內。

package com.example.demo.utils.security;

import com.example.demo.dao.SysPermissionDao;

import com.example.demo.pojo.SysPermission;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.security.access.ConfigAttribute;

import org.springframework.security.access.SecurityConfig;

import org.springframework.security.web.FilterInvocation;

import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;

import org.springframework.security.web.util.matcher.AntPathRequestMatcher;

import org.springframework.stereotype.Service;

import javax.servlet.http.HttpServletRequest;

import java.util.*;

/**

* 權限配置資源管理器

*

* @Author: 我愛大金子

* @Description: 權限配置資源管理器

* @Date: Create in 17:17 2017/7/5

*/

@Service

public class CustomFilterInvocationSecurityMetadataSource implements FilterInvocationSecurityMetadataSource {

@Autowired

private SysPermissionDao sysPermissionDao;

private HashMap<String, Collection<ConfigAttribute>> map =null;

/**

* 加載權限表中所有權限

*/

public void loadResourceDefine(){

map = new HashMap<>();

Collection<ConfigAttribute> array;

ConfigAttribute cfg;

List<SysPermission> permissions = sysPermissionDao.findAll();

for(SysPermission permission : permissions) {

array = new ArrayList<>();

cfg = new SecurityConfig(permission.getName());

//此處只添加了用戶的名字，其實還可以添加更多權限的信息，例如請求方法到ConfigAttribute的集合中去。此處添加的信息將會作為MyAccessDecisionManager類的decide的第三個參數。

array.add(cfg);

//用權限的getUrl() 作為map的key，用ConfigAttribute的集合作為 value，

map.put(permission.getUrl(), array);

}

//此方法是為了判定用戶請求的url 是否在權限表中，如果在權限表中，則返回給 decide 方法，用來判定用戶是否有此權限。如果不在權限表中則放行。

@Override

public Collection<ConfigAttribute> getAttributes(Object object) throws IllegalArgumentException {

if(map ==null) loadResourceDefine();

//object 中包含用戶請求的request 信息

HttpServletRequest request = ((FilterInvocation) object).getHttpRequest();

AntPathRequestMatcher matcher;

String resUrl;

for(Iterator<String> iter = map.keySet().iterator(); iter.hasNext(); ) {

resUrl = iter.next();

matcher = new AntPathRequestMatcher(resUrl);

if(matcher.matches(request)) {

return map.get(resUrl);

}

return null;

}

@Override

public Collection<ConfigAttribute> getAllConfigAttributes() {

return null;

}

@Override

public boolean supports(Class<?> clazz) {

return true;

}

六、根據權限設置連接

對于權限管理，我們可能希望，在一個用戶訪問的界面中，不是等到用戶點擊了超鏈接之后，才來判斷用戶有沒有這個權限，而是按照用戶擁有的權限來顯示超鏈接。這樣的設計對于用戶體驗來說，會更友好。

6.1、方法1：使用sec標簽（thymeleaf）

在html標簽中引入的Spring Security的標簽：

1	`xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4"`

sec:authentication="name":取當前登錄用戶的用戶名

1	`<title` `sec:authentication="name"></title>`

sec:authorize="hasRole('ROLE_ADMIN')：表示當前用戶是否擁有角色ROLE_ADMIN

1	`<li` `sec:authorize="hasRole('ROLE_ADMIN')"><a` `th:href="@{/admin}"> admin </a></li>`

sec:authorize="hasAuthority('admin')"：表示當前用戶是否擁有權限admin

1	`<li` `sec:authorize="hasAuthority('admin')"><a` `th:href="@{/admin}"> admin </a></li>`

6.2、方法二：代碼

在控制層用代碼獲取是否有權限，然后將標識放入內容中，頁面獲取處理

七、其它代碼

7.1、controller

IndexController.java

package com.example.demo.controller;

import com.example.demo.domain.Msg;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

/**

* 描述

*

* @Author: 我愛大金子

* @Description: 描述

* @Date: Create in 15:25 2017/7/5

*/

@Controller

public class IndexController {

/**系統首頁*/

@RequestMapping("/")

public String index(Model model){

Msg msg = new Msg("測試標題","測試內容","歡迎來到HOME頁面,您擁有index權限");

model.addAttribute("msg", msg);

return "home";

}

/**系統首頁2*/

@RequestMapping("/index2")

public String index2(Model model){

Msg msg = new Msg("測試標題2","測試內容2","歡迎來到HOME頁面,您擁有home權限");

model.addAttribute("msg", msg);

return "home";

}

@RequestMapping("/admin")

@ResponseBody

public String hello(){

return "hello admin";

}

@RequestMapping("/yk")

@ResponseBody

public String hello2(){

return "hello yk";

}

7.2、dao

SysUserDao.java

package com.example.demo.dao;

import com.example.demo.pojo.SysUser;

import org.apache.ibatis.annotations.Mapper;

/**

* 系統用戶dao

*

* @Author: 我愛大金子

@Mapper

public interface SysUserDao {

public SysUser findByUserName(String username);

}

SysPermissionDao.java

package com.example.demo.dao;

* @Date: Create in 17:05 2017/7/5

*/

@Mapper

public interface SysPermissionDao {

List<SysPermission> findAll();

List<SysPermission> findByAdminUserId(Long userId);

}

7.3、domain

Msg.java

package com.example.demo.domain;

/**

*

* @Author: 我愛大金子

* @Description: 描述

* @Date: Create in 16:14 2017/7/5

*/

public class Msg {

private String title;

private String content;

private String etraInfo;

public Msg(String title, String content, String etraInfo) {

super();

this.title = title;

this.content = content;

this.etraInfo = etraInfo;

}
