Spring Boot整合JustAuth，实现第三方登录

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：

<?xml version="1.0" encoding="UTF-8"?>

        <java.version>1.8</java.version>
    </properties>

        <dependency>

        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>

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

            </plugin>
        </plugins>
    </build>

</project>

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

<dependency>
           <groupId>cn.hutool</groupId>
           <artifactId>hutool-http</artifactId>
           <version>5.2.5</version>
       </dependency>
       <dependency>
           <groupId>org.apache.httpcomponents</groupId>
           <artifactId>httpclient</artifactId>
           <version>4.5.12</version>
       </dependency>
       <dependency>
           <groupId>com.squareup.okhttp3</groupId>
           <artifactId>okhttp</artifactId>
           <version>4.4.1</version>
       </dependency>
   </dependencies>

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！
