目的

Zuul的主要功能是路由转发和过滤器，本文对此进行实验，请求/a/hi?name=hahaha转发到a服务，请求/b/hi?name=hahaha转发到b服务。

zuul主要有以下功能：

  • 认证
  • 洞察
  • 压力测试
  • 金丝雀测试
  • 动态路由
  • 服务迁移
  • 负载脱落
  • 安全
  • 静态响应处理
  • 主动/主动流量管理

前提

这篇文章的实验环境是基于《学习SpringCloud03-Eureka》中的几个项目的，先启动注册中eureka-server, 再启动服务提供者1eureka-provider1。
将服务提供者2eureka-provider2的Application Name改为service-hello并启动。

路由网关

创建一个新项目eureka-zuul。

启动后分别访问

zuul还有很多强大的功能，学习入门阶段浅尝辄止即可，待后面搭建项目时再系统的学习。
