            org.springframework.boot

修改配置文件

application.properties

server.port=8081
#防止Cookie冲突，冲突会导致登录验证不通过
server.servlet.session.cookie.name=OAUTH2-CLIENT-SESSIONID01
#授权服务器地址
oauth2-server-url: http://localhost:8080
#与授权服务器对应的配置
security.oauth2.client.client-id=admin
security.oauth2.client.client-secret=112233
security.oauth2.client.user-authorization-uri=${oauth2-server-url}/oauth/authorize
security.oauth2.client.access-token-uri=${oauth2-server-url}/oauth/token
security.oauth2.resource.jwt.key-uri=${oauth2-server-url}/oauth/token_key

在启动类上添加@EnableOAuth2Sso注解来启用单点登录功能

package com.yjxxt.oauth2client01demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;

@SpringBootApplication
@EnableOAuth2Sso
public class Oauth2client01demoApplication {

   public static void main(String[] args) {
      SpringApplication.run(Oauth2client01demoApplication.class, args);
   }

}

添加接口用于获取当前登录用户信息

package com.yjxxt.oauth2client01demo.controller;

import org.springframework.security.core.Authentication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")
public class UserController {
    
    @GetMapping("/getCurrentUser")
    public Object getCurrentUser(Authentication authentication) {
        return authentication;
    }

}

修改认证服务器配置

修改授权服务器中的AuthorizationServerConfig类，将绑定的跳转路径为

http://localhost:8081/login，并添加获取秘钥时的身份认证

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
            //配置client_id
            .withClient("admin")
            //配置client-secret
            .secret(passwordEncoder.encode("112233"))
            //配置访问token的有效期
            .accessTokenValiditySeconds(3600)
            //配置刷新token的有效期
            .refreshTokenValiditySeconds(864000)
            //配置redirect_uri，用于授权成功后跳转
            // .redirectUris("http://www.baidu.com")
            //单点登录时配置
            .redirectUris("http://localhost:8081/login")
            //配置申请的权限范围
            .scopes("all")
            //自动授权配置
            .autoApprove(true) 
            //配置grant_type，表示授权类型
            .authorizedGrantTypes("authorization_code","password","refresh_token");
}

@Override
public void configure(AuthorizationServerSecurityConfigurer security) {
    // 获取密钥需要身份认证，使用单点登录时必须配置
    security.tokenKeyAccess("isAuthenticated()");
}  

测试

启动授权服务和客户端服务；

访问客户端需要授权的接口http://localhost:8081/user/getCurrentUser

会跳转到授权服务的登录界面；

授权后会跳转到原来需要权限的接口地址，展示登录用户信息；
