**SpringCloud2.x搭建完整Demo(五) - 集成Zuul路由**

**1.配置Zuul路由**

**2.配置过滤访问**

**3.配置安全访问**

**---------------------------------------------------------------------------------------------------------------------------**

### **1.配置Zuul路由** ###

**1.1 **新建Zuul模块【myspringcloud-zuul-gateway】,引入POM依赖

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <artifactId>myspringcloud</artifactId>
            <groupId>com.en</groupId>
            <version>1.0-SNAPSHOT</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <artifactId>myspringcloud-zuul-gateway</artifactId>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
        </dependencies>
    </project>

1.2 【myspringcloud-zuul-gateway】修改application.yml文件

server:
      port: 9501
    
    eureka:
      client: # 客户端进行Eureka注册的配置
        service-url:
          defaultZone: http://admin:root@eureka:7001/eureka,http://admin:root@eureka2:7002/eureka,http://admin:root@eureka3:7003/eureka
        register-with-eureka: false
    
    spring:
      application:
        name:  myspringcloud-zuul-gateway
    
    zuul:
      routes:
        users:
          path: /users-proxy/**
          serviceId: myspringcloud-provider-users-hystrix
      ignored-services:
        "*"
      prefix: /myspringcloud-api

1.3 创建启动类

package com.en;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
    
    @SpringBootApplication
    @EnableZuulProxy
    public class ZuulApp {
        public static void main(String[] args) {
            SpringApplication.run(ZuulApp.class,args);
        }
    }

1.4 因为Zuul目前对springboot2.1.2支持不好，所以对父工程springboot版本进行降级

<dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-dependencies</artifactId>
                    <version>2.0.7.RELEASE</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>

1.5 启动注册中心，生产者用户服务，正常访问和通过Zuul代理访问正常

### **2.配置过滤访问** ###

2.1 【myspringcloud-zuul-gateway】 修改application.yml配置，增加产品微服务

server:
      port: 9501
    
    eureka:
      client: # 客户端进行Eureka注册的配置
        service-url:
          defaultZone: http://admin:root@eureka:7001/eureka,http://admin:root@eureka2:7002/eureka,http://admin:root@eureka3:7003/eureka
        register-with-eureka: false
    
    spring:
      application:
        name:  myspringcloud-zuul-gateway
    
    zuul:
      routes:
        users:
          path: /users-proxy/**
          serviceId: myspringcloud-provider-users-hystrix
        product:
          path: /product-proxy/**
          serviceId: myspringcloud-provider-product
      ignored-services:
        "*"
      prefix: /myspringcloud-api

2.2 因为产品服务配置了加密访问，所以Zuul模块也需要追加过滤处理，新建AuthorizedRequestFilter

package com.en.filter;
    
    import com.netflix.zuul.ZuulFilter;
    import com.netflix.zuul.context.RequestContext;
    import org.springframework.cloud.netflix.zuul.filters.support.FilterConstants;
    
    import java.nio.charset.Charset;
    import java.util.Base64;
    
    
    public class AuthorizedRequestFilter extends ZuulFilter {
        @Override
        public String filterType() {
            return FilterConstants.PRE_TYPE;
        }
    
        @Override
        public int filterOrder() {
            return 0;
        }
    
        @Override
        public boolean shouldFilter() {
            return true;
        }
    
        @Override
        public Object run(){
            // 获取当前请求的上下文
            RequestContext currentContext = RequestContext.getCurrentContext() ;
            // 认证的原始信息
            String auth = "admin:root";
            // 进行一个加密的处理
            byte[] encodedAuth = Base64.getEncoder()
                    .encode(auth.getBytes(Charset.forName("US-ASCII")));
            String authHeader = "Basic " + new String(encodedAuth);
            currentContext.addZuulRequestHeader("Authorization", authHeader);
            return null;
        }
    }

2.3 新建配置类，启动时加载filter

package com.en.config;
    
    import com.en.filter.AuthorizedRequestFilter;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class ZuulConfig {
        @Bean
        public AuthorizedRequestFilter getAuthorizedRequestFilter() {
            return new AuthorizedRequestFilter() ;
        }
    }

2.4 因为降低了springboot版本，所以生产者产品服务数据库驱动类需要进行修改

driver-class-name: com.mysql.jdbc.Driver # 配置MySQL的驱动程序类

2.5 通过Zuul代理调用产品服务

### **3.配置安全访问** ###

3.1 【myspringcloud-zuul-gateway】修改pom文件，增加安全访问模块

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-security</artifactId>
            </dependency>

3.2 【myspringcloud-zuul-gateway】修改application.yml配置文件，增加用户配置

security:
        user:
          name: admin
          password: root

3.3 再次访问之前接口的时候提示输入用户名密码，输入之后接口调用成功

到这里，Springcloud常用五大组件Demo已经全部搭建完毕，剩下的Config配置中心Netflix版的感觉不是很好用，以后有时间分享一下alibaba的，还剩下SpringCloudStream和SpringCloudSleuth都需要集成消息中间件，就不放在Demo程序中了。
