1、建立父类Maven工程，删除掉所有包和文件夹，只身下pom.xml

2、配置父工程pom.xml

注：其中最重要的是spring-boot-dependencies的type和scope，如果不配置，则自工程的版本管理无法生效；

<?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.zemel</groupId>
	<artifactId>microboot</artifactId>
	<version>1.0.0</version>
	<packaging>pom</packaging>

	<name>microboot</name>
	<url>http://maven.apache.org</url>

	<properties>
		<jdk.version>1.8</jdk.version>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<dependencyManagement>
		<dependencies>
			<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies -->
			<dependency>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-dependencies</artifactId>
				<version>1.5.4.RELEASE</version>
				<!-- 所有依赖包的版本控制统一 -->
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

	<build>
		<finalName>microboot</finalName>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>${jdk.version}</source>
					<target>${jdk.version}</target>
					<encoding>${project.build.sourceEncoding}</encoding>
				</configuration>
			</plugin>
		</plugins>
	</build>

	<modules>
		<module>microboot-base</module>
	</modules>
</project>

或者用spring-boot-starter-parent

<?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.zemel</groupId>
	<artifactId>microboot</artifactId>
	<version>1.0.0</version>
	<packaging>pom</packaging>

	<name>microboot</name>
	<url>http://maven.apache.org</url>

	<properties>
		<jdk.version>1.8</jdk.version>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-parent</artifactId>
		<version>2.0.5.RELEASE</version>
	</parent>

	<!-- <dependencyManagement> <dependencies> https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies 
		<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> 
		<version>1.5.4.RELEASE</version> 所有依赖包的版本控制统一 <type>pom</type> <scope>import</scope> 
		</dependency> </dependencies> </dependencyManagement> -->

	<build>
		<finalName>microboot</finalName>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>${jdk.version}</source>
					<target>${jdk.version}</target>
					<encoding>${project.build.sourceEncoding}</encoding>
				</configuration>
			</plugin>
		</plugins>
	</build>

	<modules>
		<module>microboot-base</module>
	</modules>
</project>

3、建立子工程

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.zemel</groupId>
    <artifactId>microboot</artifactId>
    <version>1.0.0</version>
  </parent>
  <artifactId>microboot-base</artifactId>
  <name>microboot-base</name>
  <url>http://maven.apache.org</url>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
    <dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-web</artifactId>
    </dependency>
  </dependencies>
</project>

4、建立测试控制器

package com.zemel.micorboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@EnableAutoConfiguration
public class SampleController {

	@GetMapping("/")
	@ResponseBody
	public String home(){
		return "Hello World!";
	}
	
	public static void main(String[] args) {
		SpringApplication.run(SampleController.class, args);
	}
	
}
