server.port=8181  #这里的配置表示，访问/baidu/** 直接重定向到http://www.baidu.com zuul.routes.baidu.path=/baidu/** zuul.routes.baidu.url=http://www.baidu.com  #反响代理配置 #这里的配置类似nginx的反响代理 #当请求/api/**会直接交给listOfServers配置的服务器处理 #当stripPrefix=true的时候 （http://127.0.0.1:8181/api/user/list -> http://192.168.1.100:8080/user/list） #当stripPrefix=false的时候（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重写配置 #这里的配置，相当于访问/index/** 会直接渲染/home的请求内容(和直接请求/home效果一样), url地址不变 zuul.routes.index.path=/index/** zuul.routes.index.url=forward:/home
