配置授权服务器

package io.spring2go.authcodeserver.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;

//授权服务器配置
@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServer extends
        AuthorizationServerConfigurerAdapter {

    @Override
    public void configure(ClientDetailsServiceConfigurer clients)
            throws Exception {
        clients.inMemory()
            .withClient("clientapp")
            .secret("112233")
            .redirectUris("http://localhost:9001/callback")
            // 授权码模式
            .authorizedGrantTypes("authorization_code")
            .scopes("read_userinfo", "read_contacts");
    }

}

配置资源服务器

package io.spring2go.authcodeserver.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;

//资源服务配置
@Configuration
@EnableResourceServer
public class OAuth2ResourceServer extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .anyRequest()
            .authenticated()
        .and()
            .requestMatchers()
            .antMatchers("/api/**");
    }

}

编写资源api

package io.spring2go.authcodeserver.api;

import org.springframework.http.ResponseEntity;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class UserController {

    // 资源API
    @RequestMapping("/api/userinfo")
    public ResponseEntity<UserInfo> getUserInfo() {
        User user = (User) SecurityContextHolder.getContext()
                .getAuthentication().getPrincipal();
        String email = user.getUsername() + "@spring2go.com";

        UserInfo userInfo = new UserInfo();
        userInfo.setName(user.getUsername());
        userInfo.setEmail(email);

        return ResponseEntity.ok(userInfo);
    }

}

public class UserInfo {

    private String name;

    private String email;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

}

启动类

package io.spring2go.authcodeserver;

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

@SpringBootApplication
public class AuthCodeServerApplication {

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

readme

基于授权码模式+Spring Security OAuth2的最简授权服务器

操作方式

1. 获取授权码

浏览器请求：

http://localhost:8080/oauth/authorize?client_id=clientapp&redirect_uri=http://localhost:9001/callback&response_type=code&scope=read_userinfo

注意：state参数暂忽略

响应案例：

http://localhost:9001/callback?code=8uYpdo

#2. 获取访问令牌

curl -X POST --user clientapp:112233 http://localhost:8080/oauth/token -H
"content-type: application/x-www-form-urlencoded" -d
"code=8uYpdo&grant_type=authorization_code&redirect_uri=http%3A%2F%2Flocalh
ost%3A9001%2Fcallback&scope=read_userinfo"

案例响应：

{
    "access_token": "3e7279ef-0453-4356-8104-579503e38a3e",
    "token_type": "bearer",
    "expires_in": 43199,
    "scope": "read_userinfo"
}

3. 调用API

image.png

curl -X GET http://localhost:8080/api/userinfo -H "authorization: Bearer 36cded80-b6f5-43b7-bdfc-594788a24530"

案例响应：

{
    "name": "bobo",
    "email": "bobo@spring2go.com"
}

这样简单授权服务器就搭建成功了
