springcloud 服务提供者向Eureka 注册中心提供服务

一、新建一个maven项目

二、在pom.xml 中加入如下配置

<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>

  <groupId>com.purchase</groupId>

  <artifactId>bt-purchase-service</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <name>bt-purchase-service</name>

  <description>bt-purchase-service</description>

  <parent>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-parent</artifactId>

        <version>1.4.0.RELEASE</version> 

        <relativePath/>

    </parent>

    <properties>   

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <java.version>1.8</java.version>

    </properties>

    <dependencies>

        <dependency>

            <groupId>org.springframework.cloud</groupId>

            <artifactId>spring-cloud-starter-eureka-server</artifactId>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-test</artifactId>

            <scope>test</scope>

        </dependency>

    </dependencies>

    <dependencyManagement>

        <dependencies>

            <dependency>

                <groupId>org.springframework.cloud</groupId>

                <artifactId>spring-cloud-dependencies</artifactId>

                <version>Camden.SR3</version>

                <type>pom</type>

                <scope>import</scope>

            </dependency>

        </dependencies>

    </dependencyManagement>

</project>

三、在src/main/resources 下新建 application.yml 加入如下配置

server:

  port: 8762

eureka:

  client:

    serviceUrl:

      defaultZone: http://localhost:9999/eureka/  

spring:

  application:

    name: service-purchase

注： defaultZone: http://localhost:9999/eureka/  为注册中心地址   name: service-purchase  为该服务在注册中心的名称

四、编写启动类

package com.purchase.app;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication

@EnableEurekaClient

public class PurchaseApp {

public static void main(String[] args) {

SpringApplication.run(PurchaseApp.class, args);

}

}

注：@EnableEurekaClient 为必须加入的注解

启动后，如下图

五、打开注册中心界面，就会发现服务已经注册进来
