springcloud项目搭建

springCloud项目搭建

1.新建maven项目

pom文件：

<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">

2.创建Eureka Server

步骤：右键项目 > 新建module > spring initializr > next > 填写group和artifact点击next > Cloud DisCovery > 勾选Eureka server点击next > 填写模块名称 点击finish

pom文件：继承主项目pom

<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">

            <artifactId>spring-cloud-starter-netflix-eureka-serverartifactId>
        dependency>
    dependencies>
project>

应用文件：

package com.demo.server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer
@SpringBootApplication
public class ServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServerApplication.class, args);
    }

}

配置文件：

server.port=8761

eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

spring.application.name=eureka-server

3.创建Eureka Client

步骤：同server

    }

    @Value("${server.port}")
    String port;

    @RequestMapping("/hi")
    public String home(@RequestParam(value = "name", defaultValue = "forezp") String name) {
        return "hi " + name + " ,i am from port:" + port;
    }
}

配置文件：

server.port=8762
spring.application.name=eureka-client
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
