Zuul 可以適當的對多個 Amazon Auto Scaling Groups 進行路由請求。

首先新建maven專案，加入如下依賴

<dependencyManagement>

</dependencyManagement>

package com.pp.zuul;

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

@EnableZuulProxy
@SpringBootApplication
public class App  {
    public static void main( String[] args ) {
    	SpringApplication.run(App.class, args);
    }
}
 

package com.pp.zuul;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HomeController {
	
	@RequestMapping("/index")
	public Object index() {
		return "index";
	}
	
	@RequestMapping("/home")
	public Object home() {
		return "home";
	}
}
 

server.port=8181

#這裡的配置表示，訪問/baidu/** 直接重定向到http://www.baidu.com
zuul.routes.baidu.path=/baidu/**
zuul.routes.baidu.url=http://www.baidu.com

#反響代理配置
#這裡的配置類似nginx的反響代理
#當請求/api/**會直接交給listOfServers配置的伺服器處理
#當stripPrefix=true的時候 （http://127.0.0.1:8181/api/user/list -> http://192.168.1.100:8080/user/list）
#當stripPrefix=false的時候（http://127.0.0.1:8181/api/user/list -> http://192.168.1.100:8080/api/user/list）
zuul.routes.api.path=/api/**
zuul.routes.api.stripPrefix=false
api.ribbon.listOfServers=192.168.1.100:8080,192.168.1.101:8080,192.168.1.102:8080

#url重寫配置
#這裡的配置，相當於訪問/index/** 會直接渲染/home的請求內容(和直接請求/home效果一樣), url地址不變
zuul.routes.index.path=/index/**
zuul.routes.index.url=forward:/home
