使用指定的URL,使用負載均衡,你可以使用regexmapper,在serviceId和路由之間,提供一個約定,他使用正則表達式,命名組,去將serviceId的變量,注入到router pattern里面去,這里其實提到了幾個概念,regexmapper,一個叫variables from serviceId,還有一個叫route pattern,直接講概念可能比較抽象You can provide a convention between serviceId and routes by using regexmapper. It uses regular-expression named groups to extract variables from serviceId and inject them into a route pattern, as shown in the following example:microservice-gateway-zuul-reg-exp讓他成為一個最簡單的zuulhttps://cloud.spring.io/spring-cloud-netflix/reference/html/#_zuul_http_client@Bean public PatternServiceRouteMapper serviceRouteMapper() {return new PatternServiceRouteMapper("(?<name>^.+)-(?<version>v.+$)","${version}/${name}"); }我們看一下這個代碼public PatternServiceRouteMapper(String servicePattern, String routePattern) {this.servicePattern = Pattern.compile(servicePattern);this.routePattern = routePattern; }這里是servicePattern和routePattern,routePattern是什么,這邊routePattern就解釋了就是路由的表達式,路由的正則表達式,其實就是把servicePattern這個里面的變量,注入到routePattern這個里面去,這個就是所謂的PatternServiceRouteMapper,然后我們來分析一下,serviceId就是以"(?<name>^.+)-(?<version>v.+$)"這種表達式命名的,有一個name的變量,有一個version的變量,然后他會映射成什么樣的映射路徑呢,我們之前是沒有version的我們把spring.application.name=microservice-simple-provider-user改成spring.application.name=microservice-simple-provider-user-v1localhost:8040/v1/microservice-simple-provider-user/simple/1就可以訪問到用戶微服務的這個東西,就相當于訪問localhost:7900/simple/1這就說明我們已經實現了,serviceId of myusers-v1 is mapped to route /v1/myusers/**,spring.application.name=microservice-simple-provider-user-v1就是這個東西,代碼servicePattern and routePattern這兩個參數都得有,如果servicePattern和serviceId不匹配,假設我現在是這樣的,microservice-simple-provider-user,根本不符合正則表達式,就是你這邊寫了和沒寫是一樣的@Bean public PatternServiceRouteMapper serviceRouteMapper() {return new PatternServiceRouteMapper("(?<name>^.+)-(?<version>v.+$)","${version}/${name}");
