spring-cloud入门之eureka-server(服务发现)
作者:大黄蜂coder
本篇文章主要介绍了spring-cloud入门之eureka-server(服务发现),小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
前言
Eureka是一个服务发现和注册框架,细的来说,我们可以分为eureka-server(服务发现)和eureka-client(服务注册)两个,本次我们对eureka-server(服务发现)做一个项目搭建,作为spring-cloud的开篇。

项目结构
maven结构大家应该都清楚(不清楚的需要补一补,百度关于maven的文章不计其数),下面我们来看一看这些关键文件的配置
代码编写
cppba-spring-cloud > pom.xml
<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.cppba</groupId> <artifactId>cppba-spring-cloud</artifactId> <version>1.0.0</version> <packaging>pom</packaging> <name>${project.artifactId}</name> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.5.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> <spring-cloud.version>Dalston.SR2</spring-cloud.version> </properties> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <modules> <module>cppba-spring-cloud-eureka-server</module> </modules> </project>
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> <!--打包可执行的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 @SpringBootApplication public class SpringCloudEurekaServerApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudEurekaServerApplication.class, args); } }
application.properties
server.port=8761 eureka.instance.hostname=eureka-server eureka.client.registerWithEureka=false eureka.client.fetchRegistry=false eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
到此项目搭建完成
启动项目
我们启动SpringCloudEurekaServerApplication中的main方法,访问http://127.0.0.1:8761
到此,eureka-server(服务发现)项目搭建成功
