SpringCloud ： 两个微服务进程之间通信（远程调用）

1.     加依赖（依赖tcloud-user-provider）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0modelVersion>      <groupId> com.svw.tbox.tcloud.user groupId>    <artifactId>tcloud-user-consumerartifactId>    <version>0.0.1-SNAPSHOTversion>    <name>tcloud-user-consumername>    <url>http://maven.apache.orgurl>      <dependencies>       <dependency>           <groupId>com.pateo.cloudgroupId>           <artifactId>tcloud-user-providerartifactId>           <version>0.0.1-SNAPSHOTversion>       dependency>    dependencies> project>

1.     启动类中声明RestTemplate

packagecom.svw.tbox.tcloud.user.consumer;   import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; import org.springframework.web.client.RestTemplate;   @SpringBootApplication publicclass ConsumerApplication {    @Bean    public RestTemplate restTemplate(){       returnnew RestTemplate();    }    publicstaticvoid main(String[] args) {       SpringApplication.run(ConsumerApplication.class, args);    } }

1.    配置微服务端口

tcloud-user-provider端口配置为8000 在tcloud-user-provider\src\main\resources\ 中添加文件application.properties ，内容配置端口 server.port = 8000   或者在application.yml中添加 server:   port: 9000

tcloud-user-consumer端口配置为9000 tcloud-user-consumer\src\main\resources\application.properties 中添加 server.port = 9000   或者在application.yml中添加 server:   port: 9000

1.     Controller中远程调用

packagecom.svw.tbox.tcloud.user.consumer.controller; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.client.RestTemplate; importcom.svw.tbox.tcloud.user.consumer.entity.User;   @RestController publicclass TboxController {    @Autowired    private RestTemplate restTemplate;       @GetMapping("/user/{name}")    public List likeName(@PathVariable String name){       returnthis.restTemplate.getForObject("http://localhost:8000/likeName/"+name, List.class) ;    } }

效果

1.     启动tcloud-user-provider

 

2.     启动tcloud-user-consumer

 

调用过程如下：

访问http://localhost:9000/user/hrf
