Spring Boot Security 整合 JWT 實現 無狀態的分布式API接口

發布時間：2020-07-21 21:23:21 來源：網絡 閱讀：1641 作者：程序員果果 欄目：編程語言

簡介

JSON Web Token（縮寫 JWT）是目前最流行的跨域認證解決方案。JSON Web Token 入門教程 - 阮一峰，這篇文章可以幫你了解JWT的概念。本文重點講解Spring Boot 結合 jwt ，來實現前后端分離中，接口的安全調用。

快速上手

之前的文章已經對 Spring Security 進行了講解，這一節對涉及到 Spring Security 的配置不詳細講解。若不了解 Spring Security 先移步到 Spring Boot Security 詳解。

建表

DROP TABLE IF EXISTS `user`;
DROP TABLE IF EXISTS `role`;
DROP TABLE IF EXISTS `user_role`;
DROP TABLE IF EXISTS `role_permission`;
DROP TABLE IF EXISTS `permission`;

CREATE TABLE `user` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) NOT NULL,
`password` varchar(255) NOT NULL,
PRIMARY KEY (`id`) 
);
CREATE TABLE `role` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,
PRIMARY KEY (`id`) 
);
CREATE TABLE `user_role` (
`user_id` bigint(11) NOT NULL,
`role_id` bigint(11) NOT NULL
);
CREATE TABLE `role_permission` (
`role_id` bigint(11) NOT NULL,
`permission_id` bigint(11) NOT NULL
);
CREATE TABLE `permission` (
`id` bigint(11) NOT NULL AUTO_INCREMENT,
`url` varchar(255) NOT NULL,
`name` varchar(255) NOT NULL,
`description` varchar(255) NULL,
`pid` bigint(11) NOT NULL,
PRIMARY KEY (`id`) 
);

INSERT INTO user (id, username, password) VALUES (1,'user','e10adc3949ba59abbe56e057f20f883e'); 
INSERT INTO user (id, username , password) VALUES (2,'admin','e10adc3949ba59abbe56e057f20f883e'); 
INSERT INTO role (id, name) VALUES (1,'USER');
INSERT INTO role (id, name) VALUES (2,'ADMIN');
INSERT INTO permission (id, url, name, pid) VALUES (1,'/user/hi','',0);
INSERT INTO permission (id, url, name, pid) VALUES (2,'/admin/hi','',0);
INSERT INTO user_role (user_id, role_id) VALUES (1, 1);
INSERT INTO user_role (user_id, role_id) VALUES (2, 1);
INSERT INTO user_role (user_id, role_id) VALUES (2, 2);
INSERT INTO role_permission (role_id, permission_id) VALUES (1, 1);
INSERT INTO role_permission (role_id, permission_id) VALUES (2, 1);
INSERT INTO role_permission (role_id, permission_id) VALUES (2, 2);

驗證

登錄，獲取token

curl -X POST -d "username=admin&password=123456" http://127.0.0.1:8080/auth/login

返回

eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTU1NDQ1MzUwMX0.sglVeqnDGUL9pH1oP3Lh9XrdzJIS42VKBApd2nPJt7e1TKhCEY7AUfIXnzG9vc885_jTq4-h8R6YCtRRJzl8fQ

不帶token訪問資源

curl -X POST -d "name=zhangsan" http://127.0.0.1:8080/admin/hi

返回，拒絕訪問

{
    "timestamp": "2019-03-31T08:50:55.894+0000",
    "status": 403,
    "error": "Forbidden",
    "message": "Access Denied",
    "path": "/auth/login"
}

攜帶token訪問資源

curl -X POST -H "Authorization: eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImV4cCI6MTU1NDQ1MzUwMX0.sglVeqnDGUL9pH1oP3Lh9XrdzJIS42VKBApd2nPJt7e1TKhCEY7AUfIXnzG9vc885_jTq4-h8R6YCtRRJzl8fQ" -d "name=zhangsan" http://127.0.0.1:8080/admin/hi

返回正確

hi zhangsan , you have 'admin' role
