服務生產與消費-實踐作業(yè)

使用第2章-Eureka實踐作業(yè)中建好的中心，之前我們已經建好了服務生產者，現在在服ServiceControllerimportorg.springframework.web.bind.annotation.PathVariable;importorg.springframework.web.bind.annotation.RequestMap;import*CreatedbyMyonpublicclass{ ("publicStringo(@PathVariableStringname)returnname+"sayoEurekafrom}}##HTTP(Tomcat)port:name:micro-:returnname+" oEurekafrom{publicpublicclass*CreatedbyMyon<?<?xmlversion="1.0"encoding="UTF-<projectxmlns=" " <artifactId>spring-boot-starter-<relativePath/><!--lookupparentfromrepository--<project.build.sourceEncoding>UTF-<project.reporting.outputEncoding>UTF-<artifactId>spring-cloud-starter-<artifactId>spring-cloud-<artifactId>spring-boot-maven-##HTTP(Tomcat)port:name:micro-:service-defaultZone:#applicationservice-url:編寫啟動類，在啟動類上添加@SpringBootApplication@EnableDiscovery 這是一個Eureka importimportimport;import publicstaticvoidmain(String[]{SpringApplication.run(ControllerApplication.class,} te te()returnnew }}通過@LoadBalanced注解，調用netflix的ILoadBalancer實現客戶端負載均衡。然后通過CalloService、CalloController這兩個類去調用服務提供者提供的o接口，關鍵代碼importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Value;importorg.springframework.http.ResponseEntity;*CreatedbyMyonpublicclass @Value("${app.service-privateStringpublicStringcallo(Stringname)//是一個ResponseEntityresult=restTemte.postForEntity(appServiceUrl+"o/"+name,null,return(String)}importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.web.bind.annotation.GetMap;importorg.springframework.web.bind.annotation.RestController;
