SpringCloud注册中心(Eureka)

注册中心的作用就是用来方便接口暴露出来的一个管理工具，如果所有的接口只是暴露出来，没有一个同一的管理工具，又有谁知道你暴露了哪些接口了，Eureka是一个springcloud的服务注册和发现模块

搭建注册中心项目（EurekaDemo）

1、创建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.cppdy</groupId>

  <artifactId>EurekaDemo</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <parent>

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

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

        <version>1.5.9.RELEASE</version>

        <relativePath />

    </parent>

    <properties>

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

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

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

    </properties>

    <dependencies>

        <!-- eureka server -->

        <dependency>

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

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

        </dependency>

        <!-- spring boot test -->

        <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>Dalston.RC1</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>

    <repositories>

        <repository>

            <id>spring-milestones</id>

            <name>Spring Milestones</name>

            <url>https://repo.spring.io/milestone</url>

            <snapshots>

                <enabled>false</enabled>

            </snapshots>

        </repository>

    </repositories>

</project>

2、创建application.yml配置文件

server:

  port: 9000

eureka:

  instance:

    hostname: 127.0.0.1

  client:

    register-with-eureka: false

    fetch-registry: false

    service-url:

      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

3、创建启动类（EurekaApp）

package com.cppdy;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication

@EnableEurekaServer

public class EurekaApp {

    public static void main(String[] args) {

        SpringApplication.run(EurekaApp.class, args);

    }

}

4、访问http://localhost:9000/，出现以下界面，表示注册中心项目搭建成功
