1 pom.的主要文件 我引入的thymeleaf-extras-springsecurity5,springboot2.1.6 <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
<!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 --> <dependency> <groupId>org.thymeleaf.extras</groupId> <artifactId>thymeleaf-extras-springsecurity5</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> 2 controller [@Controller](https://my.oschina.net/u/1774615)
public class KungfuController {
private final String PREFIX = "pages/"; @RequestMapping("/") public String index() { System.out.println("hello word"); return "welcome"; } @RequestMapping("/userlogin") public String loginPage() { return PREFIX+"login1"; } @GetMapping("/level1/{path}") public String level1(@PathVariable("path")String path) { return PREFIX+"level1/"+path; } @GetMapping("/level2/{path}") public String level2(@PathVariable("path")String path) { return PREFIX+"level2/"+path; } @GetMapping("/level3/{path}") public String level3(@PathVariable("path")String path) { return PREFIX+"level3/"+path; }
}
//配置下
@EnableWebSecurity public class mySecurity extends WebSecurityConfigurerAdapter {
//為啥引入這個bean ,因為在securety在5.0后使用系統的登錄模板,默認把密碼給加密啦,這個寫的是不讓密碼加密
@Bean public static NoOpPasswordEncoder passwordEncoder() { return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance(); } protected void configure(HttpSecurity http) throws Exception { //定制請求的授權規則 http.authorizeRequests().antMatchers("/").permitAll() .antMatchers("/level1/**").hasRole("VIP1") .antMatchers("/level2/**").hasRole("VIP2") .antMatchers("/level3/**").hasRole("VIP3"); //開啟自動登錄的功能 http.formLogin(); //開啟自動配置的注銷功能 http.logout().logoutSuccessUrl("/"); } public void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser("mao").password("123").roles("VIP1","VIP2") .and().withUser("zhang").password("123").roles("VIP1","VIP3").and() .withUser("li").password("123").roles("VIP2","VIP3"); }
} //該模板都是尚學堂的
