spring-cloud入門之eureka-server（服務發現）

前言

Eureka是一個服務發現和註冊框架，細的來說，我們可以分為eureka-server（服務發現）和eureka-client（服務註冊）兩個，本次我們對eureka-server（服務發現）做一個項目搭建，作為spring-cloud的開篇。

項目結構

maven結構大家應該都清楚（不清楚的需要補一補，百度關於maven的文章不計其數），下面我們來看一看這些關鍵文件的配置

代碼編寫

cppba-spring-cloud > pom.xml

cppba-spring-cloud-eureka-server > 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> <artifactId>cppba-spring-cloud-eureka-server</artifactId> <packaging>jar</packaging> <name>${project.artifactId}</name> <parent> <groupId>com.cppba</groupId> <artifactId>cppba-spring-cloud</artifactId> <version>1.0.0</version> </parent> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> </dependencies> <build> <finalName>${project.name}</finalName> <plugins> <!--打包可執行的jar--> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build></project>

SpringCloudEurekaServerApplication.java

 package com.cppba;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;@EnableEurekaServer@SpringBootApplicationpublic class SpringCloudEurekaServerApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudEurekaServerApplication.class, args); }}

application.properties

 server.port=8761eureka.instance.hostname=eureka-servereureka.client.registerWithEureka=falseeureka.client.fetchRegistry=falseeureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

到此項目搭建完成

啟動項目

我們啟動SpringCloudEurekaServerApplication中的main方法，訪問http://127.0.0.1:8761

到此，eureka-server（服務發現）項目搭建成功
