Gateway+Springsecurity+OAuth2.0+JWT 实现分布式统一认证授权！

目录

1. OAuth2.0授权服务

2. 资源服务

3. Gateway网关

4. 测试

在SpringSecurity+OAuth2.0 搭建认证中心和资源服务中心-CSDN博客 ​​​​​​

基础上整合网关和JWT实现分布式统一认证授权。

大致流程如下：

1、客户端发出请求给网关获取令牌

2、网关收到请求，直接转发给授权服务

3、授权服务验证用户名、密码等一系列身份，通过则颁发令牌给客户端

4、客户端携带令牌请求资源，请求直接到了网关层

5、网关对令牌进行校验（验签、过期时间校验....）、鉴权（对当前令牌携带的权限）和访问资源所需的权限进行比对，如果权限有交集则通过校验，直接转发给微服务

6、微服务进行逻辑处理

1. OAuth2.0授权服务
