SpringBoot+Maven 多模块项目的构建、运行、打包

项目使用的工具:

*  IntelliJ IDEA
 *  JDK 1.8  
    
 *  apache-maven-3.3.9

项目的目录:

*  主项目 springboot-multi
 *  子模块 entity、dao、service、web

一、使用IDEA创建一个SpringBoot项目 : File -> new -> Project 项目名称为springboot-multi

二、删除项目中的src目录，把pom.xml中的项目打包方式改为pom，如下：

<groupId>com.example</groupId>
    	<artifactId>springboot-multi</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	
    	<packaging>pom</packaging>

三、创建springboot-multi项目的子模块，在项目上右键单击，选择：new -> Module。

四、创建四个子模块后，删除子模块中 src/main/java、src/main/java下的所有文件（如果没有文件跳过此操作），只保留web子模块的SpringBoot的Application主启动类。

五、主项目pom.xml (注意<modules>标签是否指定了子模块)

<modelVersion>4.0.0</modelVersion>
    
    	<groupId>com.example</groupId>
    	<artifactId>springboot-multi</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	
    	<packaging>pom</packaging>
    
    	<name>springboot-multi</name>
    	<description>Demo project for Spring Boot</description>
    
    	<modules>
    		<module>web</module>
    		<module>service</module>
    		<module>dao</module>
    		<module>entity</module>
    	</modules>
    
    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>1.5.10.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>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    	</dependencies>
    
    	
    	<build>
    		<plugins>
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-compiler-plugin</artifactId>
    				<version>3.1</version>
    				<configuration>
    					<source>${java.version}</source>
    					<target>${java.version}</target>
    				</configuration>
    			</plugin>
    
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-surefire-plugin</artifactId>
    				<version>2.19.1</version>
    				<configuration>
    					<skipTests>true</skipTests>    
    				</configuration>
    			</plugin>
    		</plugins>
    	</build>

六、web子模块pom.xml（依赖service、dao、entity子模块）

<modelVersion>4.0.0</modelVersion>
    
    	<groupId>com.example</groupId>
    	<artifactId>web</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>web</name>
    	<description>Demo project for Spring Boot</description>
    
    	<parent>
    		<groupId>com.example</groupId>
    		<artifactId>springboot-multi</artifactId>
    		<version>0.0.1-SNAPSHOT</version>
            <relativePath>../pom.xml</relativePath>
    	</parent>
    
    	<dependencies>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>service</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>dao</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>entity</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    	</dependencies>
    
        
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        
                        <mainClass>com.example.WebApplication</mainClass>
                        <layout>ZIP</layout>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>

七、service子模块pom.xml(依赖 dao 、entity子模块)

<modelVersion>4.0.0</modelVersion>
    
    	<groupId>com.example</groupId>
    	<artifactId>service</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>service</name>
    	<description>Demo project for Spring Boot</description>
    
    	<parent>
    		<groupId>com.example</groupId>
    		<artifactId>springboot-multi</artifactId>
    		<version>0.0.1-SNAPSHOT</version>
    		<relativePath>../pom.xml</relativePath>
    	</parent>
    
    	<dependencies>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>dao</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>entity</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    	</dependencies>

八、dao子模块pom.xml （依赖entity子模块）

<modelVersion>4.0.0</modelVersion>
    
    	<groupId>com.example</groupId>
    	<artifactId>dao</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>dao</name>
    	<description>Demo project for Spring Boot</description>
    
    	<parent>
    		<groupId>com.example</groupId>
    		<artifactId>springboot-multi</artifactId>
    		<version>0.0.1-SNAPSHOT</version>
    		<relativePath>../pom.xml</relativePath>
    	</parent>
    
    	<dependencies>
    		<dependency>
    			<groupId>com.example</groupId>
    			<artifactId>entity</artifactId>
    			<version>0.0.1-SNAPSHOT</version>
    		</dependency>
    	</dependencies>

九、entity子模块

<modelVersion>4.0.0</modelVersion>
    
    	<groupId>com.example</groupId>
    	<artifactId>entity</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>entity</name>
    	<description>Demo project for Spring Boot</description>
    
        <parent>
            <groupId>com.example</groupId>
            <artifactId>springboot-multi</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <relativePath>../pom.xml</relativePath>
        </parent>

十、pom.xml文件中需要注意的就是：

*  主项目的modules标签指定的子模块是否正确
 *  子模块之间的依赖
 *  子模块的parent标签

十一、web子模块的Application启动类:

@RestController
    @SpringBootApplication
    public class WebApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(WebApplication.class, args);
    	}
    
    	@RequestMapping(value = "/test",method = RequestMethod.GET)
    	public String test(){
    		return "test success";
    	}
    }

十二、执行main方法启动项目，访问localhost:8080/test，出现如下页面表示项目搭建成功：

![20180301160308434][]

十三、项目打包命令: mvn clean package 或者 使用右边工具栏的图形化界面打包也可以：

![20180301160558554][]

十四、打包成功日志：
