6.Spring Cloud初相识-------Zool路由

前言：

在生产环境中，我们不可能将每个服务的真实信息暴漏出去，因为这样太不安全。

我们会选择使用路由代理真实的服务信息，由它负责转发给真实的服务。

新建一个Zool：

1.添加依赖

<?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">
	<modelVersion>4.0.0</modelVersion>

	<groupId>com.xm.cloud</groupId>
	<artifactId>cl_zool</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>cl_zool</name>
	<description>This is a Web about springcloud</description>

	<parent>

	</build>


</project>

2.修改配置

server.port=9090
spring.application.name=cl-zool-gateway

eureka.client.service-url.defaultZone=http://127.0.0.1:7001/eureka/
#服务名统一前缀
zuul.prefix=/xm
#所有服务真实名称隐藏
zuul.ignored-services="*"
zuul.routes.myHello.service-id=CL-HELLO-PRODUCER
zuul.routes.myHello.path=/myHello/**

3.开启注解

package com.xm.cloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@EnableDiscoveryClient
@EnableZuulProxy
@SpringBootApplication
public class ClZoolApplication {

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

测试：

开启eureka7001、服务生产者8001、路由zool9090

1.访问Eureka客户端：

2.访问服务生产者localhost:8001/hello

3.访问不加前缀真实服务名称http://localhost:9090/CL-HELLO-PRODUCER/hello：

4.访问加前缀真实服务名称http://localhost:9090/xm/CL-HELLO-PRODUCER/hello：

5.访问不加前缀路由服务名称http://localhost:9090/myHello/hello：

6.访问加前缀路由服务名称http://localhost:9090/xm/myHello/hello：
