搭建单机版Eureka Server

Posted 2021-01-13 yangjiming

1.使用spring官网生成模板项目，https://start.spring.io/，spring cloud版本Edgware.SR4，spring boot版本1.5.16

2. 修改项目的pom文件

<?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>

    <groupId>com.example</groupId>
    <artifactId>eurekaServer</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>eurekaServer</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.16.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </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>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- spring cloud 默认配置启动器 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        <!-- spring cloud Eureka Server 启动器 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

3.修改全局配置文件 application.properties

eclipse安装Properties Editor，可以添加中文注释，在Eclipse的 【Help】-> 【 Install New Software.. 】 打开安装插件的向导输入地址，
http://propedit.sourceforge.jp/eclipse/updates/ 稍等片刻，选择Properties Editor安装后重启即可使用。

# 设置spring应用命名，可以自定义，非必要
spring.application.name=eureka-server
# 设置Eureka Server WEB控制台端口，自定义
server.port=8761

#是否将自己注册到Eureka-Server中，默认的为true
eureka.client.registerWithEureka=false
#是否从Eureka-Server中获取服务注册信息，默认为true
eureka.client.fetchRegistry=false

4.启动类增加@EnableEurekaServer 注解来开启Eureka Server服务

@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

 5.访问Eureka Server WEB控制台

http://localhost:8761/

解决问题

启动类增加@EnableEurekaServer注解后，提示EnableEurekaServer cannot be resolved to a type，查找网上问题无法解决，遂删除掉maven库中的boot和cloud文件夹，重新更新库问题解决，原因jar包问题
