本文详细介绍了如何使用SpringBoot和SpringCloud在IDEA环境下搭建微服务注册中心Eureka，包括项目创建、依赖配置、启动类编写、资源文件设置、Dockerfile创建及部署流程。

构建spring cloud体系微服务中心

1.在idea中创建一个maven项目

2.在pom.xml中添加依赖和构建插件

<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">

            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>

                    <dockerDirectory>${project.build.outputDirectory}</dockerDirectory>

                </configuration>
            </plugin>
        </plugins>

    </build>
</project>

3.创建启动类

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

4. resouces资源文件夹下添加application.properties文件

spring.application.name=spring-cloud-eureka
server.port=8000
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/

5.创建Dockerfile

FROM java:8
MAINTAINER "joy-brave"<347247745@qq.com>
ADD mic-service-eureka.jar app.jar
EXPOSE 8000
CMD java -jar app.jar

6.在idea中mvn install完成和启动起来

7. 在浏览中输入http://127.0.0.1:8000/ ，恭喜你已经完成服务注册中心的搭建
