springboot2.1.4整合和配置（一）—— 使用idea搭建boot maven聚合项目

1.创建一个boot项目，file —> new project —>Maven —> next，起好名字，进去pom里！这是我的pom，可以直接复制使用！注意名字！！！再删除无关文件（具体看结构图）。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

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>2.1.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->

<groupId>com.example</groupId>
<artifactId>boot-jh-demo</artifactId>

<version>1.0-SNAPSHOT</version>
<modules>
<module>boot-web</module>

<scope>test</scope>
</dependency>

<!-- spring-boot的web启动的jar包 -->

</dependencies>

<properties>
<!--<thymeleaf.version>3.0.9.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.2.2</thymeleaf-layout-dialect.version>-->
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<!-- 使用maven打包 -->
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
</project>

2.创建demo项目的子模块，在项目上右键单击选择：new ->Module ->Spring  Initializr,先创建名为 boot-web的boot子项目，再选择：new -> Module ->Maven 创建分别为boot-service,boot-dao,boot-model ，boot-util 4个子项目   创建完成后目录如下：项目结构图。

3.更改父工程的pom.xml   文件为如下 添加<modules>标签是否指定了子模块

<modules>
<module>boot-web</module>
<module>boot-service</module>
<module>boot-dao</module>
<module>boot-model</module>
<module>boot-util</module>
</modules>

3.在web的pom.xml中引入service，service引入dao，到引入model，model引入util，并把parent指向父项目。

3.1   web的pom.xml

<?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>

<parent>
<artifactId>boot-jh-demo</artifactId>
<groupId>com.example</groupId>
<version>1.0-SNAPSHOT</version>
</parent>

<artifactId>boot-web</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>boot-web</name>
<description>Demo project for Spring Boot</description>

<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>boot-service</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>

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

</project>

3.2 service的pom.xml

<?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">
<parent>
<artifactId>boot-jh-demo</artifactId>
<groupId>com.example</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>boot-service</artifactId>

<dependencies>

<!-- 添加对上层的依赖 -->
<dependency>
<groupId>com.example</groupId>
<artifactId>boot-dao</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>

3.3dao的pom.xml

<?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">
<parent>
<artifactId>boot-jh-demo</artifactId>
<groupId>com.example</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>boot-dao</artifactId>
<dependencies>
<!-- 添加对上层的依赖 -->
<dependency>
<groupId>com.example</groupId>
<artifactId>boot-model</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>

3.3model和service，dao一样，此处略过！

4.测试，在web的pom中引入boot常用的jar包，web中创建controller文件夹下再创建TestController

@Controller
public class TestController {

@RequestMapping(value = "/hello",method = RequestMethod.GET)
public String test(){
return "hello";
}
}

5.启动web下的启动类.

6.如需要源码，留言！
