Spring Boot整合JustAuth，实现第三方登录

关于JustAuth
史上最全的整合第三方登录的开源库（官方是这样说的）

项目源码已放到GitHub: https://github.com/nateshao/SpringBoot-test

个人博客

本次操作流程如下：

创建Spring Boot项目

导入依赖

修改Client ID，Client Secret，redirectUri

启动项目–完成

创建SpringBoot初始化项目
打开IEDA，点击File-New-Project-Spring Initializr，接着添加spring-boot-starter-web，spring-boot-devtools，lombok。

创建完成后的pom.xml，如下：

4.0.0
org.springframework.boot spring-boot-starter-parent 2.3.0.RELEASE
com.stj
nateshao
0.0.1-SNAPSHOT
nateshao

             </exclusion>
         </exclusions>
     </dependency>
     <dependency>
         <groupId>me.zhyd.oauth</groupId>
         <artifactId>JustAuth</artifactId>
         <version>1.15.4-alpha</version>
     </dependency>

 <build>
     <plugins>
         <plugin>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
     </plugins>
 </build>

然后再添加hutool-http，httpclient，okhttp。如下：

cn.hutool hutool-http 5.2.5
org.apache.httpcomponents httpclient 4.5.12
com.squareup.okhttp3 okhttp 4.4.1

编写controller

package com.stj.controller;

import me.zhyd.oauth.config.AuthConfig;
import me.zhyd.oauth.model.AuthCallback;
import me.zhyd.oauth.request.AuthGiteeRequest;
import me.zhyd.oauth.request.AuthRequest;
import me.zhyd.oauth.utils.AuthStateUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**

• @author shaotongjie
• @date 2020/6/12 10:51
  */
  @RestController
  @RequestMapping(“/oauth”)
  public class JustAuthController { /**
  • 获取授权链接并跳转到第三方授权页面
    *
  • @param response response
  • @throws IOException response可能存在的异常
    */
    @RequestMapping(“/render/{source}”)
    public void renderAuth(HttpServletResponse response) throws IOException {
    AuthRequest authRequest = getAuthRequest();
    String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());
    response.sendRedirect(authorizeUrl);
    } /**
  • 用户在确认第三方平台授权（登录）后， 第三方平台会重定向到该地址，并携带code、state等参数
    *
  • @param callback 第三方回调时的入参
  • @return 第三方平台的用户信息
    */
    @RequestMapping(“/callback/{source}”)
    public Object login(AuthCallback callback) {
    AuthRequest authRequest = getAuthRequest();
    return authRequest.login(callback);
    } /**
  • 获取授权Request
    *
  • @return AuthRequest
    */
    private AuthRequest getAuthRequest() {
    return new AuthGiteeRequest(AuthConfig.builder()
    .clientId(“clientId”) //clientId
    .clientSecret(“clientSecret”) //clientSecret
    .redirectUri(“redirectUri”) //redirectUri
    .build());
    }
  }

到了这里，就登录gitee，创建第三方应用

然后修改Client ID，Client Secret，redirectUri

private AuthRequest getAuthRequest() {
return new AuthGiteeRequest(AuthConfig.builder()
.clientId(“6a46c8bbe31b34dd4a5c54e73c828a4e3d3d022c1532cbfe652b11959538b0ce”)
.clientSecret(“2d327f4c7e7081c9e9b1ee71828b9ffde9729bed3ef1def4eb25c0ff620a5dac”)
.redirectUri(“http://localhost:8080/oauth/callback/gitee”)
.build());
}

最后访问：http://localhost:8080/oauth/render/gitee

出现下面界面，说明成功啦！
