Idea下SpringCloud2实验（二、Eureka-服务提供者）

2025-02-02 技术教程

一、创建SpringBoot项目springcloud-eureka-client-order，过程如上一篇，有一点需要注意，选择Eureka客户端依赖

二、配置文件
1、pom.xml

<?xml version="1.0" encoding="UTF-8"?><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>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.4.RELEASE</version> <relativePath/>  </parent> <groupId>com.jane</groupId> <artifactId>springcloud-eureka-client-order</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springcloud-eureka-client-order</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Greenwich.SR1</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>  <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> <version>2.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-openfeign-core</artifactId> <version>2.0.2.RELEASE</version> </dependency> <dependency> <groupId>io.github.openfeign.form</groupId> <artifactId>feign-form-spring</artifactId> <version>3.2.2</version> </dependency>  </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build></project>

2、启动文件

package com.jane.springcloudeurekaclientorder;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.openfeign.EnableFeignClients;import org.springframework.cloud.openfeign.FeignClient;import org.springframework.context.annotation.ComponentScan;@EnableDiscoveryClient@SpringBootApplication@ComponentScan("com.jane")@EnableFeignClientspublic class SpringcloudEurekaClientOrderApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudEurekaClientOrderApplication.class, args); }}

3、application.properties

server.port=6010spring.application.name=springcloud-eureka-client-ordereureka.client.serviceUrl.defaultZone=http://127.0.0.1:6001/eureka/

4、服务提供API,TestController

package com.jane.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class TestController { @Value("${server.port}") String port; @RequestMapping(value = "/test", method = RequestMethod.GET) public String test(){ return "hello，this is client-order:" + port; }}

三、启动服务
1、服务正常

2、查看注册中心
