1.建立Project

1）File->New Projecthtml

2)选中Maven,点击Nextjava

3）输入GroupId,ArtifactId,Versionmysql

4）设置工程名，位置等，点Finish。web

5）工程主界面spring

6）删除src文件夹和demo.iml,修改pom文件。sql

pom.xml内容以下数据库

<?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.company</groupId>
    <artifactId>demo</artifactId>
    <packaging>pom</packaging>
    <version>1.0.0</version>
    
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <url>http://localhost:8181/repository/maven-releases/</url>
        </repository>

        <snapshotRepository>
            <id>nexus-snapshot</id>
            <url>http://localhost:8181/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>
</project>

注意事项：nexus-releases、nexus-snapshot对应着maven的settings.xml中server,若没有配置则将distributionManagement标签删除apache

7）IDEA中maven配置（-Dmaven.multiModuleProjectDirectory=$M2_HOME）json

2.建立module

1)选中demo工程，右键New,选中Moduleapi

2)选中maven,点Next

3)填写ArtifactId,点击Next

4)填写Module name,点击Finish。

5)重复步骤1-4，建立demo-data,demo-service,demo-web三个module，建立完成后如图。

6)修改pom.xml

demo-base中pom.xml

demo-data中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>demo</artifactId>
        <groupId>com.company</groupId>
        <version>1.0.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

</project>

demo-service中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">

        </dependency>
    </dependencies>
</project>

demo-web中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"

            <version>1.0.0</version>
        </dependency>
    </dependencies>
</project>

3.将demo-web改Web工程

在demo-web->src->main,右键new->Diretory

2)输入webapp,点ok

3)在webapp继续建立WEB-INF文件夹以及index.html,而后在WEB-INF下建立web.xml

结构图以下

index.html

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
</head>
<body>
    Hello,World!
</body>
</html>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

</web-app>

4.将web项目部署到tomcat并运行

1）点击工程右上角

2）点"+"->tomcat Server->Local

3）配置tomcat

4)运行

运行结果：

5.补充-工程说明

1）各module说明

demo-base:真个demo的基础依赖包，也能够公用。
demo-data:数据层（即DAO），配置对应数据库。
demo-service:服务层，事务配置。
demo-web:web层（即controller）。

项目依赖：demo-web=>demo-service=>demo-service=>demo-data=>demo-base

2）单一module工程结构说明

File=>Project Structure

main/java：源码目录
main/resources：资源文件目录，能够放对应配置，编译时到classpath
test/java：测试类目录
