springcloud zuul 入门配置

1、zuul-Service 网关服务的核心代码

pom.xml

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-zuul</artifactId>
</dependency>

<!-- 热部署插件 -->
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>springloaded</artifactId>
</dependency>

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

yml

server: 
  port: 9500
 
spring: 
  application:
    name: microservicecloud-zuul
 
eureka: 
  client: 
    service-url: 
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka  
  instance:
    instance-id: gateway9500.com
    prefer-ip-address: true 
 

zuul: 
  prefix: /myzuul
 # ignored-services: microservicecloud-order  # 忽略单个服务名称
  ignored-services: "*"                       # 忽略所有的服务名称
  routes: 
    myorder.serviceId: microservicecloud-order
    myorder.path: /myorder/**

SpringBootApplication.java

@SpringBootApplication
@EnableZuulProxy
public class Zuul_SpringApplication{

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

orderService微服务 的不是本文的重点，配置省略。

2、测试

先启动 Eureka，
再先启动 orderService 服务
最后启动 ZuulService 服务

先访问 order 服务， http://localhost:8001/order/get/2 ，响应请求的数据

再通过 zuul 服务， 请求 为 http://127.0.0.1:9500/myzuul/myorder/order/get/2 ， 响应相同的数据。
