Spring Security实现统一登录与权限控制

2022-03-24 分类：野生技术 阅读(224) 评论(0)

1  项目介绍

最开始是一个单体应用，所有功能模块都写在一个项目里，后来觉得项目越来越大，于是决定把一些功能拆分出去，形成一个一个独立的微服务，于是就有个问题了，登录、退出、权限控制这些东西怎么办呢？总不能每个服务都复制一套吧，最好的方式是将认证与鉴权也单独抽离出来作为公共的服务，业务系统只专心做业务接口开发即可，完全不用理会权限这些与之不相关的东西了。于是，便有了下面的架构图：

下面重点看一下统一认证中心和业务网关的建设

2  统一认证中心

这里采用 Spring Security + Spring Security OAuth2
OAuth2是一种认证授权的协议，是一种开放的标准。最长用到的是授权码模式和密码模式，在本例中，用这两种模式都可以。
首先，引入相关依赖
最主要的依赖是 spring-cloud-starter-oauth2 ，引入它就够了

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-oauth2</artifactId>
  <version>2.2.5.RELEASE</version>
</dependency>

这里Spring Boot的版本是2.6.3
完整的pom如下：

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Resource
    private DataSource dataSource;
    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(new JdbcClientDetailsService(dataSource));
    }

    /**
     * 密钥对

    @Bean
    public KeyPair keyPair() {
        KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(new ClassPathResource(\"jwt.jks\"), \"123456\".toCharArray());

    }

    @Bean
    public TokenKeyEndpoint tokenKeyEndpoint() {
        return new TokenKeyEndpoint(jwtAccessTokenConverter());
    }
}

说明：


  • 客户端是从数据库加载的
  • 密码模式下必须设置一个AuthenticationManager
  • 采用JWT生成token是因为它轻量级，无需存储可以减小服务端的存储压力。但是，为了实现退出功能，不得不将它存储到Redis中
  • 必须要对JWT进行加密，资源服务器在拿到客户端传的token时会去校验该token是否合法，否则客户端可能伪造token

  • 此处对token进行了增强，在token中加了几个字段分别表示用户ID和部门ID

    客户端表结构如下：
DROP TABLE IF EXISTS `oauth_client_details`;
CREATE TABLE `oauth_client_details`  (
  `client_id` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT \'客户端ID\',
  `resource_ids` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `client_secret` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT \'客户端密钥\',
  `scope` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `authorized_grant_types` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT \'授权类型\',
  `web_server_redirect_uri` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `authorities` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `access_token_validity` int(11) NULL DEFAULT NULL COMMENT \'access_token的有效时间\',
  `refresh_token_validity` int(11) NULL DEFAULT NULL COMMENT \'refresh_token的有效时间\',
  `additional_information` varchar(4096) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `autoapprove` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT \'是否允许自动授权\',
  PRIMARY KEY (`client_id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = DYNAMIC;

INSERT INTO `oauth_client_details` VALUES (\'hello\', \'order-resource\', \'$2a$10$1Vun/h63tI4C48BqLsy2Zel5q5M2VW6w8KThoMfxww49wf9uv/dKy\', \'all\', \'authorization_code,password,refresh_token\', \'http://www.baidu.com\', NULL, 7200, 7260, NULL, \'true\');
INSERT INTO `oauth_client_details` VALUES (\'sso-client-1\', NULL, \'$2a$10$CxEwmODmsp/HOB7LloeBJeqUjotmNzjpk2WmjxtPxAeOYifQWLfhW\', \'all\', \'authorization_code\', \'http://localhost:9001/sso-client-1/login/oauth2/code/custom\', NULL, 180, 240, NULL, \'true\');

本例中采用RSA非对称加密，密钥文件用的是java自带的keytools生成的
Spring Security实现统一登录与权限控制
将来，认证服务器用私钥对token加密，然后将公钥公开

package com.soa.supervision.uaa.controller;

import com.nimbusds.jose.jwk.JWKSet;
import com.nimbusds.jose.jwk.RSAKey;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import java.security.KeyPair;
import java.security.interfaces.RSAPublicKey;
import java.util.Map;

/**
 * @Author ChengJianSheng
 * @Date 2022/2/15
 */
@RestController
public class KeyPairController {

    @Autowired
    private KeyPair keyPair;

    @GetMapping(\"/rsa/publicKey\")
    public Map<String, Object> getKey() {
        RSAPublicKey publicKey = (RSAPublicKey) this.keyPair.getPublic();
        RSAKey key = new RSAKey.Builder(publicKey).build();
        return new JWKSet(key).toJSONObject();
    }
}

配置WebSecurity

在WebSecurity中主要是配置用户，以及哪些请求需要认证以后才能访问

package com.soa.supervision.uaa.config;

import com.soa.supervision.uaa.service.impl.UserDetailsServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.autoconfigure.security.servlet.EndpointRequest;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
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;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

/**
 * @Author ChengJianSheng
 * @Date 2022/2/14
 */
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .requestMatchers(EndpointRequest.toAnyEndpoint()).permitAll()
                .antMatchers(\"/rsa/publicKey\", \"/menu/tree\").permitAll()
                .anyRequest().authenticated()
                .and().formLogin().permitAll()
                .and()
                .csrf().disable();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

        if (null == authUserDTO) {
            throw new UsernameNotFoundException(\"用户不存在\");
        }
        if (!authUserDTO.isEnabled()) {
            throw new LockedException(\"账号被禁用\");
        }
        Set<SimpleGrantedAuthority> authorities = authUserDTO.getRoles().stream().map(SimpleGrantedAuthority::new).collect(Collectors.toSet());

登录

默认的登录url是/login，本例中没有自定义登录页面，而是使用默认的登录页面
正常的密码模式下，输入用户名和密码，登录成功以后返回token。本例中使用密码模式，所以写了个登录接口，而且也是取巧，覆盖了默认的/oauth/token端点

3  网关

在这里，网关相当于OAuth2中的资源服务器这么个角色。网关代理了所有的业务微服务，如果说那些业务服务是资源的，那么网关就是资源的集合，访问网关就是访问资源，访问资源就要先认证再授权才能访问。同时，网关又相当于一个公共方法，因此在这里做鉴权是比较合适的。

菜单权限在Redis中是这样存储的
url -> [角色编码, 角色编码, 角色编码]
Spring Security实现统一登录与权限控制

查询SQL

SELECT
	t1.url,
	t3.`code` AS role_code 
FROM
	sys_menu t1
	LEFT JOIN sys_role_menu t2 ON t1.id = t2.menu_id
	LEFT JOIN sys_role t3 ON t2.role_id = t3.id
WHERE t1.url is NOT NULL;

存储到Redis

HSET \"/soas-order/order/pageList\" \"[\\\"admin\\\",\\\"org\\\"]\"
HSET \"/soas-order/order/save\" \"[\\\"admin\\\",\\\"enterprise\\\"]\"

说明:

  • 公钥可以从远程获取，也可以放在本地从本地读取。上面代码中，被注释调的就是测试一下从本地读取公钥。

从源码中我们也可以看出有多种方式，本例中采用的是从远程获取，因此在前面application.yml中配置了spring.security.oauth2.resourceserver.jwt.jwk-set-uri

Spring Security实现统一登录与权限控制

响应工具类ResponseUtils

package com.soa.supervision.gateway.util;

import com.alibaba.fastjson.JSON;
import com.tgf.common.domain.RespResult;
import com.tgf.common.util.RespUtils;
import org.springframework.core.io.buffer.DataBuffer;
import org.springframework.core.io.buffer.DataBufferUtils;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.server.reactive.ServerHttpResponse;
import reactor.core.publisher.Mono;

import java.nio.charset.StandardCharsets;

/**
 * @Author ChengJianSheng
 * @Date 2022/2/16
 */
public class ResponseUtils {
    public static Mono<Void> writeErrorInfo(ServerHttpResponse response, HttpStatus httpStatus) {
        response.getHeaders().set(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
        response.getHeaders().set(\"Access-Control-Allow-Origin\", \"*\");
        response.getHeaders().set(\"Cache-Control\", \"no-cache\");

        RespResult respResult = RespUtils.fail(httpStatus.value(), httpStatus.getReasonPhrase());
        String body = JSON.toJSONString(respResult);
        DataBuffer buffer = response.bufferFactory().wrap(body.getBytes(StandardCharsets.UTF_8));

        return response.writeWith(Mono.just(buffer))
                .doOnError(error -> DataBufferUtils.release(buffer));
    }
}

鉴权通过以后，可以解析token，并将一些有用的信息放到header中传给下游的业务服务，这样的话业务服务就无需再解析token了，在网关这里统一处理是最适合的了
TokenFilter

package com.soa.supervision.gateway.filter;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.nimbusds.jose.JWSObject;
import com.soa.supervision.gateway.constant.AuthConstants;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;

import java.text.ParseException;

/**
 * 只有当请求URL匹配路由规则时才会执行全局过滤器
 *
 * @Author ChengJianSheng
 * @Date 2021/12/15
 */
@Slf4j
@Component
public class TokenFilter implements GlobalFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        String token = request.getHeaders().getFirst(AuthConstants.JWT_TOKEN_HEADER);

        if (StringUtils.isBlank(token)) {
            return chain.filter(exchange);
        }

        String realToken = token.trim().substring(7);

        try {
            JWSObject jwsObject = JWSObject.parse(realToken);
            String payload = jwsObject.getPayload().toString();
            JSONObject jsonObject = JSON.parseObject(payload);
            String userId = jsonObject.getString(\"userId\");
            String deptId = jsonObject.getString(\"deptId\");
            request = request.mutate()
                    .header(AuthConstants.HEADER_USER_ID, userId)
                    .header(AuthConstants.HEADER_DEPT_ID, deptId)
                    .build();
            //  可以把整个Payload放到请求头中
//            exchange.getRequest().mutate().header(\"user\", payload).build();
            exchange = exchange.mutate().request(request).build();
        } catch (ParseException e) {
            log.error(\"解析token失败！原因: {}\", e.getMessage(), e);
        }

        return chain.filter(exchange);
    }
}

最后，是几个常量类
AuthConstants

package com.soa.supervision.gateway.constant;

/**
 * @Author ChengJianSheng
 * @Date 2021/11/17
 */
public class AuthConstants {

    public static final String ROLE_PREFIX = \"ROLE_\";
    public static final String JWT_TOKEN_HEADER = \"Authorization\";
    public static final String JWT_TOKEN_PREFIX = \"Bearer \";

    public static final String TOKEN_WHITELIST_PREFIX = \"TOKEN:\";

    public static final String HEADER_USER_ID = \"x-user-id\";
    public static final String HEADER_DEPT_ID = \"x-dept-id\";
}

RedisConstants

package com.soa.supervision.gateway.constant;

/**
 * @Author ChengJianSheng
 * @Date 2022/2/16
 */
public class RedisConstants {
    //  资源角色映射关系
    public static final String URL_ROLE_MAP_HK = \"URL_ROLE_HS\";
    //  有效的TOKEN
    public static final String ONLINE_TOKEN_PREFIX_KV = \"ONLINE_TOKEN:\";
}

最后，数据库脚本
