文章标签 java spring 网关 redis hg 文章分类 架构后端开发

1.我们把三个服务分别注册到nacos中

1.1:pom文件中加入 nacos依赖(三个服务都得加)

<dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

1.2：在application.yml中配置nacos连接地址

cloud:
  nacos:
    discovery:
      #指定nacos server的地址
      server-addr: 127.0.0.1:8848

2.配置gateway

2.1：在application.yml中配置（注意配置顺序，顺序不对 gateway可能启动不起来）

server:
  port: 9090
spring:
  application:
    name: springcloud-oauth-gateway
  #将服务器注册到nacos中
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
    ##是否与服务发现组件进行结合，通过 serviceId 转发到具体的服务实例。默认为false，设为true便开启通过服务中心的自动根据 serviceId 创建路由的功能。
    gateway:
      discovery:
        locator:
          enabled: true
      routes:
        - id: springcloud-oauth-auth
          uri: lb://springcloud-oauth-auth
          predicates:
            - Path=/auth/**
        - id: springcloud-oauth-resource
          uri: lb://springcloud-oauth-resource
          predicates:
            - Path=/resource/**
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    password: zhangxiaoyun123
    url: jdbc:mysql://192.168.3.37/zxy_system_service?useUnicode=true&characterEncoding=utf8&useSSL=false&zeroDateTimeBehavior=convertToNull
    username: root
  ##这个的意思 是 在spring cloud服务太多的情况下 bean名字重名的情况下多 设置为true 后重名的bean覆盖以前的bean
  main:
    allow-bean-definition-overriding: true
ribbon:
  MaxAutoRetries: 2 #最大重试次数，当nacos中可以找到服务，但是服务连不上时将会重试，如果nacos中找不到服务则直接走断路器
  MaxAutoRetriesNextServer: 3 #切换实例的重试次数
  OkToRetryOnAllOperations: false  #对所有操作请求都进行重试，如果是get则可以，如果是post，put等操作没有实现幂等的情况下是很危险的,所以设置为false
  ConnectTimeout: 5000  #请求连接的超时时间
  ReadTimeout: 6000 #请求处理的超时时间

##调用方法的超时时间 在调用方配置，被该调用方的所有方法的超时时间都是该值，优先级低于下边的指定配置
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeout-in-milliseconds: 6000

3.封装获取token的方法

3.1:创建TokenService

import com.example.springcloudalibabaoauthauth.util.AuthToken;

/**
 * 2 * @Author: ZhangShuai
 * 3 * @Date: 2020/6/18 14:44
 * 4
 */
public interface TokenService {


    /**
     * 根据用户名密码获取令牌
     *
     * @param username 用户名
     * @param password 用户密码
     * @return
     */
    AuthToken passwordVerifyToken(String username, String password);
}

3.2:实现TokenService
注（这里将获取到的token存储到redis中，当访问网关的时候，去判断hadler中有没有token，判断这个token是否使用，可用才放行token）

import com.example.springcloudalibabaoauthauth.config.RedisMethod;
import com.example.springcloudalibabaoauthauth.service.TokenService;
import com.example.springcloudalibabaoauthauth.util.AuthToken;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.loadbalancer.LoadBalancerClient;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;
import org.springframework.util.Base64Utils;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

import javax.annotation.Resource;
import java.net.URI;
import java.util.Map;

/**

 */
@Service
public class TokenServiceImpl implements TokenService {
    /** 这里指的是客户端的信息和密钥 具体看数据库表 oauth_client_details **/
    private final String clientId="client";
    private final String clientSecret="admin";

    //在redis里面的过期时间 3600秒
    private final Long ExpireTime=3600l;

    @Autowired
    LoadBalancerClient loadBalancerClient;

    @Resource(name = "facePlusRestTemplate")
    RestTemplate restTemplate;

    @Autowired
    RedisMethod redisMethod;

    @Override
    public AuthToken passwordVerifyToken(String username, String password) {
        //拿着username 和password 去请求 /auth/oauth/token 来获取到token
        AuthToken token = this.passwordApplyToken(username, password);
        //如果错误信息 不为空的话  走 redis
        if (token.getError() == null && token.getError_description() == null) {
            //把token存储到redis当中
            redisMethod.setStringTime(token.getAccess_token(), token.toString(), ExpireTime);
        }
        return token;
    }

    private AuthToken passwordApplyToken(String username, String password) {
        //从nacos中获取认证服务的实例地址（因为spring security在认证服务中） 服务的名称
        ServiceInstance serviceInstance = loadBalancerClient.choose("springcloud-oauth-auth");
        //此地址就是http://ip:portx
        URI uri = serviceInstance.getUri();
        //令牌申请的地址 http://localhost:8086/auth/oauth/token
        String authUrl = uri + "/auth/oauth/token";
        //定义header
        LinkedMultiValueMap<String, String> header = new LinkedMultiValueMap<>();
        String httpBasic = getHttpBasic();
        header.add("Authorization", httpBasic);
        //定义body
        LinkedMultiValueMap<String, String> body = new LinkedMultiValueMap<>();
        body.add("grant_type", "password");
        body.add("username", username);
        body.add("password", password);
        HttpEntity<MultiValueMap<String, String>> httpEntity = new HttpEntity<>(body, header);
        //调用登录认证服务 生成jwt令牌
        ResponseEntity<Map> exchange = restTemplate.exchange(authUrl, HttpMethod.POST, httpEntity, Map.class);
        //申请令牌信息
        AuthToken authToken = makeAuthToken(exchange);
        return authToken;
    }

    /**
     * 设置token值
     *
     * @param exchange 远程调用结果
     * @return
     */
    private AuthToken makeAuthToken(ResponseEntity<Map> exchange) {
        Map bodyMap = exchange.getBody();
        AuthToken authToken = new AuthToken();
        if (bodyMap == null ||
                bodyMap.get("access_token") == null ||
                bodyMap.get("refresh_token") == null ||
                bodyMap.get("jti") == null ||
                bodyMap.get("expires_in") == null
        ) {
            authToken.setError((String) bodyMap.get("error"));
            authToken.setError_description((String) bodyMap.get("error_description"));
            return authToken;
        }
        authToken.setAccess_token((String) bodyMap.get("access_token"));//用户身份令牌
        authToken.setRefresh_token((String) bodyMap.get("refresh_token"));//刷新令牌
        authToken.setJwt_token((String) bodyMap.get("jti"));//jwt令牌
        return authToken;
    }

    /*获取httpBasic的串*/
    private String getHttpBasic() {
        String string = clientId + ":" + clientSecret;
        //将串进行base64编码
        byte[] encode = Base64Utils.encode(string.getBytes());
        return "Basic " + new String(encode);
    }
}

3.3:具体返回实体类可查看代码

4.配置gateway网关拦截器

4.1 GateWayGloFilter：网关拦截器，所有的请求都会请求网关，网关来进行转发请求

import com.alibaba.fastjson.JSON;
import com.example.springcloudalibabaoatuhgatewat.config.RedisMethod;

4.2 AuthService：当redis中token快过期的时候，拿着access_token去刷新token的类

import com.example.springcloudalibabaoatuhgatewat.util.AuthToken;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.loadbalancer.LoadBalancerClient;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;
import org.springframework.util.Base64Utils;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

import javax.annotation.Resource;
import java.net.URI;
import java.util.Map;

@Slf4j
@Service
public class AuthService {

    /** 这里指的是客户端的信息和密钥 具体看数据库表 oauth_client_details **/
    private final String clientId="client";
    private final String clientSecret="admin";

    @Autowired
    LoadBalancerClient loadBalancerClient;

    @Resource(name = "facePlusRestTemplate")
    RestTemplate restTemplate;

    /**
     * 调用服务 获取刷新令牌
     *
     * @param token
     * @return
     */
    public AuthToken refresh_token(String token) {
        //从nacos中获取认证服务的实例地址（因为spring security在认证服务中） 服务的名称
        ServiceInstance serviceInstance = loadBalancerClient.choose("springcloud-oauth-auth");
        //此地址就是http://ip:portx
        URI uri = serviceInstance.getUri();
        //令牌校验的地址 http://localhost:8086/auth/oauth/check_token
        String authUrl = uri + "/auth/oauth/token";

        //定义header
        LinkedMultiValueMap<String, String> header = new LinkedMultiValueMap<>();
        String httpBasic = getHttpBasic(clientId, clientSecret);
        header.add("Authorization", httpBasic);

        //定义body
        LinkedMultiValueMap<String, String> body = new LinkedMultiValueMap<>();
        body.add("grant_type", "refresh_token");
        body.add("refresh_token", token);

        HttpEntity<MultiValueMap<String, String>> httpEntity = new HttpEntity<>(body, header);
        //调用登录认证服务 刷新jwt令牌
        ResponseEntity<Map> exchange = restTemplate.exchange(authUrl, HttpMethod.POST, httpEntity, Map.class);

        byte[] encode = Base64Utils.encode(string.getBytes());
        return "Basic " + new String(encode);
    }

}

5.资源服务器拿到用户的登录信息

5.1 在第二章节的时候我们配置了 CustomUserInformationConverter 自定义jwt信息这个类 ,所以我们在资源服务器可以拿到这个类定义的东西，配置资源服务器 jwt解析的类

5.2 CustomUserInformationConverter ：解析jwt内容类

import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.DefaultAccessTokenConverter;
import org.springframework.stereotype.Component;

import java.util.Map;


/**
 * 2 * @Author: ZhangShuai
 * 3 * @Date: 2020/6/12 17:03
 * 4  资源服务器获取 认证服务器的自定义内容
 */
@Component
public class CustomUserInformationConverter extends DefaultAccessTokenConverter {


    @Override
    public OAuth2Authentication extractAuthentication(Map<String, ?> claims) {
        OAuth2Authentication authentication
                = super.extractAuthentication(claims);
        authentication.setDetails(claims);
        return authentication;
    }


}

5.3 JwtTokenStoreConfig：设置jwt的解析类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;

import javax.annotation.Resource;


/**
 * 2 * @Author: ZhangShuai
 * 3 * @Date: 2020/6/12 17:03
 * 4  token使用jwt的配置
 */
@Configuration
public class JwtTokenStoreConfig {

    public static final String EncryptedFile = "xmzs-jwt.jks";

    public static final String Secret = "557554";

    public static final String EncryptedFileName = "557554";

    @Resource
    private CustomUserInformationConverter customUserInformation;

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter(customUserInformation));
    }

    //使用非对称加密算法
    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter(CustomUserInformationConverter customUserInformationApadter) {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey(EncryptedFileName);
        converter.setAccessTokenConverter(customUserInformationApadter);
//        //找到 加密文件所在的地址 读取classpath里面的 xm-jwt.jks文件
//        ClassPathResource pathResource = new ClassPathResource(EncryptedFile);
//        //秘钥配置时的密码
//        KeyStoreKeyFactory keyFactory = new KeyStoreKeyFactory(pathResource, Secret.toCharArray());
//        //使用keystore得到秘钥
//        KeyPair pair = keyFactory.getKeyPair(EncryptedFileName);
//        //设置秘钥
//        converter.setKeyPair(pair);
        //DefaultAccessTokenConverter accessTokenConverter = (DefaultAccessTokenConverter) converter.getAccessTokenConverter();
        //accessTokenConverter.setUserTokenConverter(customUserInformationApadter);
        return converter;
    }

}

5.4 ResourceServerConfig ：在资源服务器配置该token解析类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;

5.5 Subject ：配置当前登录人的信息（这里面是自定义的）

import lombok.Data;

/**

 * 4
 */
@Data
public class Subject {

    /**
     * 用户id
     */
    private Long id;

    /**
     * 用户名
     */
    private String username;

}

5.6 GetSubject：获取jwt里面自定义的内容并且赋值给 Subject类（这里面是自定义的）

import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationDetails;
import org.springframework.stereotype.Component;

import java.util.LinkedHashMap;

/**
 * 2 * @Author: ZhangShuai
 * 3 * @Date: 2020/6/19 14:30
 * 4   获取当前用户的信息
 */
@Component
public class GetSubject {


    public Subject getSubject(OAuth2Authentication oAuth2Authentication) {
        OAuth2AuthenticationDetails oAuth2AuthenticationDetails = (OAuth2AuthenticationDetails) oAuth2Authentication.getDetails();
        LinkedHashMap details = (LinkedHashMap) oAuth2AuthenticationDetails.getDecodedDetails();
        Subject subject=new Subject();
        //获取自定义的id
        subject.setId(Long.parseLong(details.get("id").toString()));
        //
        subject.setUsername(String.valueOf(details.get("username")));
        return subject;
    }

}
