上一篇文章介绍了oauth2-server端的鉴权认证部分，想了下还是将三个组件分开来讲述下，因为实际场景大概都是server，resource，client分开部署的。

这篇文章介绍下oauth2-resource端的使用。（本案例使用远程token鉴权的方式，数据库的鉴权方式我个人感觉并不是很好，此文不做阐述）

资源服务器配置项目搭建：

1.构建一个简单的maven项目

2.在项目中增加spring-boot和security及oauth的依赖支持

	</dependencies>

	<build>

				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>

			</plugin>


			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>

		</plugins>
	</build>

</project>

3.配置服务参数及鉴权服务地址

server.port=8081
security.basic.enabled=false
security.oauth2.resource.id=tm-oauth-resource
security.oauth2.resource.token-info-uri=http://localhost:8080/oauth/check_token

logging.level.root=debug

4.在主启动类上启用资源服务注解

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

}

5.编写对外提供的资源服务

@RestController
public class TmResourceController {
	private static final Logger log = LoggerFactory.getLogger(TmResourceController.class);

	@RequestMapping("/api/test1")
	public Object test1() {
		log.info("访问test---1---接口");
		Map<String, Object> m = new HashMap<>();
		m.put("method", "test1");
		m.put("time", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
		return m;
	}

	@RequestMapping("/api/user")
	public Object user() {
		log.info("访问user---user---接口");

		Map<String, Object> m = new HashMap<>();
		m.put("method", "user");
		m.put("name", "皇太极");
		m.put("age", 18);
		m.put("sex", "男");
		m.put("time", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
		return m;
	}

}

6.添加资源的请求认证，及认证方式

@Configuration
public class TmResourceServerConfig extends ResourceServerConfigurerAdapter {
	
	@Autowired
	private ResourceServerProperties props;
	
	@Override
	public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
		resources.resourceId(props.getResourceId());
	}

	@Override
	public void configure(HttpSecurity http) throws Exception {
		http.authorizeRequests().antMatchers(HttpMethod.GET, "/api/user").authenticated();
	}
	
    @Bean
    public RemoteTokenServices remoteTokenServices() {
        RemoteTokenServices remoteTokenServices = new RemoteTokenServices();
        remoteTokenServices.setCheckTokenEndpointUrl(props.getTokenInfoUri());
        return remoteTokenServices;
    }

}

7.自定义security的配置（可自行扩展，此处省略）

@Configuration
public class TmWebSecurityConfig extends WebSecurityConfigurerAdapter {

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		super.configure(http);
	}

	@Override
	public void configure(WebSecurity web) throws Exception {
		web.ignoring().antMatchers("/favor.ico");
	}
}

8.启动服务，浏览器分别访问

http://localhost:8081/api/test1

http://localhost:8081/api/user

可以看到/api/user 服务已经提示未认证需要授权访问

到此oauth2-resource端服务已经搭建完成。后续会加入oauth2-client来对这个api进行验证
