微服務架構電商開發Docker部署從零起步之[003]：創建子模塊discovery-service

package com.contoso;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class DiscoveryServiceApplication {

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

package com.contoso;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DiscoveryServiceApplicationTests {

	@Test
	public void contextLoads() {
	}

}

我們的目的是要獲得spring-cloud-store/discovery-service/pom.xml配置文件內容：

<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>
	<parent>
		<groupId>com.contoso</groupId>
		<artifactId>spring-cloud-store</artifactId>
		<version>0.0.1-SNAPSHOT</version>
		<relativePath>../</relativePath>
	</parent>
	<artifactId>discovery-service</artifactId>
	<name>discovery-service</name>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
		<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
	</properties>

	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
		</dependency>

		<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>${spring-cloud.version}</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>
	</project>

同時會在spring-cloud-store/pom.xml文件配置中自動插入模塊配置數據：

<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>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.4.RELEASE</version>
		<relativePath /> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.contoso</groupId>
	<artifactId>spring-cloud-store</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>pom</packaging>
	<name>spring-cloud-store</name>
	<description>Create a Maven Project  for  Store</description>
	<properties>

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

	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
	</dependencies>
	<modules>
		<module>config-service</module>
		<module>discovery-service</module>
	</modules>
</project>

註冊中心即發現服務子模塊自動生成的代碼全部貼完，接下來在下一篇中將完善補充各個模塊配置服務配置文件，配置Dockerfile文件,配置dock-compose.yml文件，配置run.sh文件，配置manifest.yml文件，配置bootstrap.yml文件，還有如何將可執行jar服務包安裝到docker容器中，以及如何上傳鏡像到https://hub.docker.com/
