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

spring:
  security:
    oauth2:
      client:
        registration:
          github:
            client-id: d64d35f9f66ea04ba64f
            client-secret: b84a72f20fcec596deb947860cd4eacaf55b0f5b
          google:
            client-id: 195066099347-nj4et113vfl9p0aq9k5cb4hd6kg0c3hh.apps.googleusercontent.com
            client-secret: Wk5XNm8wv36R0h4zGCxWOfYn
