SpringCloud之zuul搭建

一、zuul简介

Zuul的主要功能是路由和过滤器。路由功能是微服务的一部分，比如／api/user映射到user服务，/api/shop映射到shop服务。zuul实现了负载均衡。

zuul有以下功能：

• Authentication
• Insights
• Stress Testing
• Canary Testing
• Dynamic Routing
• Service Migration
• Load Shedding
• Security
• Static Response handling
• Active/Active traffic management

二、jar包依赖

 三、启动程序

1package com.pkfare.zuul;
2
3import org.springframework.boot.SpringApplication;
4import org.springframework.boot.autoconfigure.SpringBootApplication;
5import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
6
7@EnableZuulProxy
8@SpringBootApplication
9public class Application 
10{
11    public static void main( String[] args )
12    {
13        SpringApplication.run(Application.class, args);
14    }
15}

四、配置文件

1#配置忽略的请求头
2zuul.sensitive-headers=  
3#配置对应的路由映射
4zuul.routes.usercenter-provider.stripPrefix=false
5zuul.routes.usercenter-provider.path=/user/**
6zuul.routes.usercenter-provider.serviceId=USERCENTER-PROVIDER
7#熔断时间
8hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=120000
9#熔断信号量
10zuul.semaphore.maxSemaphores=1000
11
12#服务超时间
13ribbon.ReadTimeout=180000
14ribbon.ConnectTimeout=18000
