需要完成以下步骤:

1. 创建工程并引入依赖包

   • spring-boot-starter-oauth2-client

   • spring-boot-starter-security

   • spring-boot-starter-web

2. 创建Security配置信息

3. 创建Github、Google的client-id和client-secret

#Oauth2GoogleLoginApplication.java

package com.deepincoding.oauth2googlelogin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication public class Oauth2GoogleLoginApplication {   public static void main(String[] args) {  SpringApplication.run(Oauth2GoogleLoginApplication.class, args);  }  }  

#MessageController.java

package com.deepincoding.oauth2googlelogin;

import lombok.extern.log4j.Log4j2;
import org.springframework.security.core.annotation.AuthenticationPrincipal;
import org.springframework.security.oauth2.core.user.OAuth2User;
import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController;  @RestController @Log4j2 public class MessageController {   @GetMapping("/")  public String hello(){  return "Hello Google Github.";  }   @GetMapping("/guest")  public String guest(){  return "Hello Guest.";  }   @GetMapping("/admin")  public OAuth2User admin(@AuthenticationPrincipal OAuth2User principal){  return principal;  }  }   

#SecurityConfig.java

package com.deepincoding.oauth2googlelogin;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 @Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter {   @Override  protected void configure(HttpSecurity http) throws Exception {  http  .antMatcher("/**").authorizeRequests()  .antMatchers("/", "/guest").permitAll()  .anyRequest().authenticated()  .and()  .oauth2Login();  } }  

#application.yml
