IntelliJ IDEA创建Maven聚合工程跟ssm整合详解

2019 年 11 月 14 日
筆記

一、创建一个空的项目作为存放整个项目的路径

1、选择 File——>new——>Project ——>Empty Project

2、WorkspaceforTest为项目存放文件夹。

二、maven继承：创建父-子项目，聚合工程

比如整个项目。以一个项目来演示。

|–e3-parent：父工程，打包方式pom，管理jar包的版本号。项目中所有工程都应该继承父工程。

　　|–e3-common：通用的工具类通用的pojo。打包方式jar

　　|–e3-manager：服务层工程。聚合工程。Pom工程

　　　　|–e3-manager-dao：打包方式jar

　　　　|–e3-manager-pojo：打包方式jar

　　　　|–e3-manager-interface：打包方式jar

　　　　|–e3-manager-service：打包方式：jar

　　　|–e3-manager-web：表现层工程。打包方式war

1、创建maven父工程 e3-parent

File——>New ——>Module.. ——>Maven

2、GroupId一般为公司域名倒过来写。ArtifactId写工程名字。

3、Maven home directory 在这里我选择自己安装的maven，还有User settings file 选择好本地仓库。

4、注意下e3-parent的项目路径，在WorkspaceforTest下面。

5、在e3-parent的pom.xml文件下添加<packaging>pom</packaging>,e3-parent是打成pom文件的。

6、就可以pom文件添加各种依赖了。在这里我的e3-parent的pom.xml文件如下。

e3-parent的pom.xml

1 <?xml version="1.0" encoding="UTF-8"?>    2    3 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    4

7、创建e3-common，e3-common继承父工程parent。而且为了与eclipse下面一样一种好看，common工程的目录也是在WorkspaceforTest目录下，但是是继承了parent工程

File——>New——>module——>Maven

8、common工程也是在WorkspaceforTest目录下的，所以要在Add as module to选项中选择None,如下图所示

9、Parent 中选择继承的父工程e3-parent，如下图所示，再写好ArtifactId.

10、选择maven，如果没有发生改变，就可以直接下一步。

11、注意一下路径，是在WorkspaceforTest下面。

12、再在pom.xml下面添加<packaging>jar</packaging>，如下图所示。

在这个项目的pom文件如下代码所示。

e3-common的 pom.xml

1 <?xml version="1.0" encoding="UTF-8"?>   2   3 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   4          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   5 <parent>   6 <artifactId>e3-parent</artifactId>   7 <groupId>e3.mall</groupId>   8 <version>1.0-SNAPSHOT</version>   9 <relativePath>../e3-parent/pom.xml</relativePath>  10 </parent>  11 <modelVersion>4.0.0</modelVersion>  12  13 <artifactId>e3-common</artifactId>  14 <packaging>jar</packaging>  15  16 <name>e3-common</name>  17 <dependencies>  18 <!-- 时间操作组件 -->  19 <dependency>  20 <groupId>joda-time</groupId>  21 <artifactId>joda-time</artifactId>  22 </dependency>  23 <!-- Apache工具组件 -->  24 <dependency>  25 <groupId>org.apache.commons</groupId>  26 <artifactId>commons-lang3</artifactId>  27 </dependency>  28 <dependency>  29 <groupId>org.apache.commons</groupId>  30 <artifactId>commons-io</artifactId>  31 </dependency>  32 <dependency>  33 <groupId>commons-net</groupId>  34 <artifactId>commons-net</artifactId>  35 </dependency>  36 <!-- Jackson Json处理工具包 -->  37 <dependency>  38 <groupId>com.fasterxml.jackson.core</groupId>  39 <artifactId>jackson-databind</artifactId>  40 </dependency>  41 <!-- httpclient -->  42 <dependency>  43 <groupId>org.apache.httpcomponents</groupId>  44 <artifactId>httpclient</artifactId>  45 </dependency>  46 <!-- quartz任务调度框架 -->  47 <dependency>  48 <groupId>org.quartz-scheduler</groupId>  49 <artifactId>quartz</artifactId>  50 </dependency>  51 <!-- 单元测试 -->  52 <dependency>  53 <groupId>junit</groupId>  54 <artifactId>junit</artifactId>  55 <scope>test</scope>  56 </dependency>  57 <!-- 日志处理 -->  58 <dependency>  59 <groupId>org.slf4j</groupId>  60 <artifactId>slf4j-log4j12</artifactId>  61 </dependency>  62 </dependencies>  63  64 </project>

13、创建manager工程，与common工程的方法一样。

File——>New——>module——>Maven

14、再在pom.xml下面添加<packaging>pom</packaging>，如下图所示。

e3-common的 pom.xml文件

1 <?xml version="1.0" encoding="UTF-8"?>   2 <project xmlns="http://maven.apache.org/POM/4.0.0"   3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   4          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   5 <parent>   6 <artifactId>e3-parent</artifactId>   7 <groupId>e3.mall</groupId>   8 <version>1.0-SNAPSHOT</version>   9 <relativePath>../e3-parent/pom.xml</relativePath>  10 </parent>  11 <modelVersion>4.0.0</modelVersion>  12  13 <artifactId>e3-manager</artifactId>  14 <packaging>pom</packaging>  15 <modules>  16 <module>e3-manager-pojo</module>  17 <module>e3-manager-dao</module>  18 <module>e3-manager-interface</module>  19 <module>e3-manager-service</module>  20 <module>e3-manager-web</module>  21 </modules>  22 <dependencies>  23 <dependency>  24 <artifactId>e3-common</artifactId>  25 <groupId>e3.mall</groupId>  26 <version>1.0-SNAPSHOT</version>  27 </dependency>  28 </dependencies>  29  30 <build>  31 <!-- 配置插件 -->  32 <plugins>  33 <plugin>  34 <groupId>org.apache.tomcat.maven</groupId>  35 <artifactId>tomcat7-maven-plugin</artifactId>  36 <configuration>  37 <port>8080</port>  38 <path>/</path>  39 </configuration>  40 </plugin>  41 </plugins>  42 </build>  43 </project>

15,来开始创建e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程最终都是打成jar包的，创建过程都是一样的，下面就只写出一个工程的创建过程。

以e3-manager-pojo为例。

16、选中e3-manager——>右击鼠标——>New——Module，因为e3-manager-pojo是e3-manager的子工程。

17、再在pom.xml下面添加<packaging>pom</packaging>，如下图所示。

18、e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程都是这样创建。

19、e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程的pom.xml文件

20、最后创建e3-manager-web工程，创建过程都与上面的四个过程一样。只是有一个地方需要注意，下面的截图会提示。

选中e3-manager——>右击鼠标——>New——Module，因为e3-manager-web是e3-manager的子工程。

只是下面需要注意一下。

21、再在pom.xml下面添加<packaging>war</packaging>，如下图所示。

22、e3-manager-web的pom.xml文件

 1 <?xml version="1.0" encoding="UTF-8"?>   2 <project xmlns="http://maven.apache.org/POM/4.0.0"   3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   4          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   5 <parent>   6 <artifactId>e3-parent</artifactId>   7 <groupId>e3.mall</groupId>   8 <version>1.0-SNAPSHOT</version>   9 <relativePath>../e3-parent/pom.xml</relativePath>  10 </parent>  11 <modelVersion>4.0.0</modelVersion>  12  13 <artifactId>e3-manager</artifactId>  14 <packaging>pom</packaging>  15 <modules>  16 <module>e3-manager-pojo</module>  17 <module>e3-manager-dao</module>  18 <module>e3-manager-interface</module>  19 <module>e3-manager-service</module>  20 <module>e3-manager-web</module>  21 </modules>  22 <dependencies>  23 <dependency>  24 <artifactId>e3-common</artifactId>  25 <groupId>e3.mall</groupId>  26 <version>1.0-SNAPSHOT</version>  27 </dependency>  28 </dependencies>  29  30 <build>  31 <!-- 配置插件 -->  32 <plugins>  33 <plugin>  34 <groupId>org.apache.tomcat.maven</groupId>  35 <artifactId>tomcat7-maven-plugin</artifactId>  36 <configuration>  37 <port>8080</port>  38 <path>/</path>  39 </configuration>  40 </plugin>  41 </plugins>  42 </build>  43 </project>

23、好了。到此maven聚合工程创建完成。

三、maven工程下创建resources文件夹

步骤：File——>Project Struture——>Modules——>maven工程，如果没有maven工程就点+号来添加

选择到创建resources文件夹的路径，比如图上的选择到main，右击鼠标，选择New Folder新建文件夹resources

再选择resources，右击鼠标选择Resources，可以看到resources文件夹的图标和之前不一样了，就是这样创建一个resources文件夹。再点Ok保存退出。

很明图标都不一样了。

四、整合ssm框架

直接看项目路径，直接上代码，不懂ssm框架整合的可以百度学习下。

SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>  <!DOCTYPE configuration          PUBLIC "-//mybatis.org//DTD Config 3.0//EN"          "http://mybatis.org/dtd/mybatis-3-config.dtd">  <configuration>    </configuration>

db.properties

jdbc.driver=com.mysql.jdbc.Driver  jdbc.url=jdbc:mysql://localhost:3306/e3mall?charactherEncoding=utf-8  jdbc.username=root  jdbc.password=*****

五、intellij maven工程运行

运行项目后，在控制台可以看到如下图所示。

去浏览器输入地址后可以看到项目运行成功。
