1.项目结构

2.项目依赖关系

multi-module ：外层项目

model：实体类

persistence：持久化对象

web：控制层对象

web->persistence->model

3.pom文件

3.1model

    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>model</artifactId>

        <version>0.0.1-SNAPSHOT</version>
    </parent>

3.2persistence

<?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>

    <artifactId>persistence</artifactId>

    <dependencies>
        <dependency>
            <artifactId>model</artifactId>

            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

主要注意

    <dependencies>
        <dependency>
            <artifactId>model</artifactId>
            <groupId>com.dencycheng</groupId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

因为这里要使用model里面的对象，所以把它当作依赖引入过来

3.3web

<?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>multi-module</artifactId>
        <groupId>com.dencycheng</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>web</artifactId>

    <dependencies>
        <dependency>
            <artifactId>persistence</artifactId>
            <groupId>com.dencycheng</groupId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

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

</project>

主要注意

    <dependencies>
        <dependency>
            <artifactId>persistence</artifactId>
            <groupId>com.dencycheng</groupId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

原理跟persistence类似，这里就不说明了。还有我们看见了build标签，这里先不做解释，这个是打包用的

4.打jar包

刚才上文提到的

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

为什么出现在web的pom文件中，因为启动类在web里面，所以把build标签以及里面内容放进了web的pom文件中

下面看一下web的目录结构
