SpringBoot2.1.1使用Zuul创建SpringCloud微服务Gateway网关

1、在新的SpringBoot项目中的pom.xml引入如下依赖：

		<!-- 引入Zuul starter -->
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter</artifactId>
		</dependency>
		<!-- 连接Eureka -->
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
		</dependency>

2、在pom.xml的project中加入SpringCloud的版本管理配置：

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

3、编辑配置文件application.propertites：

spring.application.name = zero4j-zuul-gateway

eureka.client.serviceUrl.defaultZone = http://admin:123456@localhost:8761/eureka/
eureka.instance.instance-id = ${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}
eureka.instance.prefer-ip-address = true

#只要访问以/api/v1/areas开头的多层目录都可以路由到服务名为zero4j-provider-area的服务上.
zuul.routes.zero4j-provider-area.path = /api/v1/areas
zuul.routes.zero4j-provider-area.service-id = zero4j-provider-area
zuul.routes.zero4j-provider-area.stripPrefix = false

server.port = 4000

4、最后在application启动类中加入@EnableDiscoveryClient和@EnableZuulProxy注解：

package com.zero4j;

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 Zero4jZuulGatewayApplication {

	public static void main(String[] args) {
		SpringApplication.run(Zero4jZuulGatewayApplication.class, args);
	}

}
