SpringBoot2.x版本整合SpringSecurity、Oauth2进行password认证

很多人在进行项目开发时都会用到Oauth2.0结合SpringSecurity或者Shiro进行权限拦截以及用户验证，网上也有很多的案例，前几天项目里边需要用到，顺便整合了进来，特此写篇博客，记录下过程。

项目结构如下：

首先准备pom.xml

MyUserDetailService.java

public class MyUserDetailsService implements UserDetailsService {
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        grantedAuthorityList.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
        return new User(username, "{noop}123456", grantedAuthorityList);
    }
}

OAuth2ServerConfig.java

package com.oauth.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;

import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;

@Configuration
@EnableAuthorizationServer
public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {

	 @Override
	    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
	        oauthServer
	                .tokenKeyAccess("permitAll()") //url:/oauth/token_key,exposes public key for token verification if using JWT tokens
	                .checkTokenAccess("isAuthenticated()") //url:/oauth/check_token allow check token
	                .allowFormAuthenticationForClients();
	    }

	    /**
	     * 注入authenticationManager
	     * 来支持 password grant type
	     */
	    @Autowired
	    private AuthenticationManager authenticationManager;

	    @Override
	    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
	        endpoints.authenticationManager(authenticationManager);
	        endpoints.allowedTokenEndpointRequestMethods(HttpMethod.GET, HttpMethod.POST);
	    }

	    @Override
	    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
	        clients.inMemory()
	                .withClient("client")
	                .secret("{noop}secret")
	                .authorizedGrantTypes("client_credentials", "password", "refresh_token")
	                .scopes("all")
	                .resourceIds("resourcesId")
	                .accessTokenValiditySeconds(1200)
	                .refreshTokenValiditySeconds(50000);
	}

}

ResourceServerConfig.java

package com.oauth.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;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

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

	@Override
	public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
		resources.resourceId("resourcesId").stateless(true);
	}

}

WebConfig.java

package com.oauth.config;

import org.springframework.context.annotation.Bean;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true)
public class WebConfig extends WebSecurityConfigurerAdapter {

	 @Override
	 protected void configure(HttpSecurity http) throws Exception {
		 http.csrf().disable();
	    http.requestMatchers().antMatchers("/oauth/**")
	    .and()
	    .authorizeRequests()
	    .antMatchers("/oauth/**").authenticated();
	 }

	/**
	 * 需要配置这个支持password模式 support password grant type
	 * @return
	 * @throws Exception
	 */
	@Override
	@Bean
	public AuthenticationManager authenticationManagerBean() throws Exception {
		return super.authenticationManagerBean();
	}

}

IndexCtrl.java

package com.oauth.ctrl;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class IndexCtrl {

	@GetMapping("hello")
	public String hello() {
		return "Hello World";
	}

	@GetMapping("api/hello")
	public String apiHello() {
		return "Hello World";
	}

}

App.java

package com.oauth;

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

@SpringBootApplication
public class App {

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

	}
}

以上就是一个代码的配置，下面启动App类，运行main函数。项目启动完成后用rest client访问hello接口

可以看到提示无效的token，接下我们请求获取token。利用CURL命令请求如下：

curl -i -X POST -d "username=admin&password=123456&grant_type=password&client_id=client&client_secret=secret" http://localhost:8888/oauth/token

可以看到，至此已经访问成功了。

也可以利用GET方式直接访问，如下：

http://localhost:8888/api/hello?access_token=cca911c0-532f-475b-83e6-3a2671a8fe07

有问题可以在下面评论，技术问题可以私聊我。
