Zuul 路由配置

我们新建一个module  microservice-zuul-3001

这里我们的zuul也注册到eureka服务里，端口3001；

我们修改下Hosts，专门为zuul搞个本地域名映射 

hosts文件 加下：

127.0.0.1  zuul.java1234.com

然后pom.xml要加上：

<!-- zuul路由网关 -->

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-zuul</artifactId>

</dependency>

完整pom.xml

搞一个 application.yml 

server:

  port: 3001

  context-path: /

spring:

  application:

    name: microservice-zuul

eureka:

  instance:

    instance-id: microservice-zuul:3001 #客户端实例名称

    prefer-ip-address: true #显示IP

  client: 

    service-url: 

      defaultZone: http://eureka2001.java1234.com:2001/eureka/,http://eureka2002.java1234.com:2002/eureka/,http://eureka2003.java1234.com:2003/eureka/ # 集群

建一个主启动类：ZuulApplication_3001

加下@EnableZuulProxy注解

package com.java1234;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
@EnableZuulProxy
public class ZuulApplication_3001 {

	public static void main(String[] args) {
		SpringApplication.run(ZuulApplication_3001.class, args);
	}
	
}

我们测试下：

启动三个eureka 然后再启动下一个1001服务，以及 zuul网关服务；

这里有两个服务；

我们直接请求：http://localhost:1001/student/list 能获取到数据；

我们用 http://zuul.java1234.com:3001/microservice-student/student/list  域名+端口+服务名称+请求地址 也能请求到数据；

说明我们的路由基本配置OK
