服务生产与消费-实践作业

使用第2章-Eureka实践作业中建好的中心，之前我们已经建好了服务生产者，现在在服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:编写启动类，在启动类上添加@SpringBootApplication@EnableDiscovery 这是一个Eureka importimportimport;import publicstaticvoidmain(String[]{SpringApplication.run(ControllerApplication.class,} te te()returnnew }}通过@LoadBalanced注解，调用netflix的ILoadBalancer实现客户端负载均衡。然后通过CalloService、CalloController这两个类去调用服务提供者提供的o接口，关键代码importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Value;importorg.springframework.http.ResponseEntity;*CreatedbyMyonpublicclass @Value("${app.service-privateStringpublicStringcallo(Stringname)//是一个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;
