建立maven java後臺聚合工具類工程：jt-manage，工程packaging型別為jar。

繼承父工程jt-parent。

com.jt.manage.pojo

com.jt.manage.mapper

com.jt.manage.service

com.jt.manage.web

pom.xml配置檔案：

<?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.jt.manage</groupId>
  <artifactId>jt-manage</artifactId>
  <packaging>pom</packaging>

  <name>jt-manage</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <parent>
  	<groupId>com.jt.parent</groupId>
  	<artifactId>jt-parent</artifactId>
  	<version>0.0.1-SNAPSHOT</version>
  </parent>
  <modules>
  	<module>jt-manage-pojo</module>
  	<module>jt-manage-mapper</module>
    <module>jt-manage-service</module>
    <module>jt-manage-web</module>
  </modules>
</project>
 

聚合工程

jt-manage-pojo

Maven水平切分管理。

pom.xml配置檔案：

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.jt.manage</groupId>
    <artifactId>jt-manage</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.jt.manage</groupId>
  <artifactId>jt-manage-pojo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>jt-manage-pojo</name>
  <url>http://maven.apache.org</url>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
  	<dependency>
  		<groupId>com.jt.common</groupId>
  		<artifactId>jt-common</artifactId>
  		<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  </dependencies>
</project>
 

jt-manage-mapper（同樣操作，建立maven工程）

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.jt.manage</groupId>
    <artifactId>jt-manage</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.jt.manage</groupId>
  <artifactId>jt-manage-mapper</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>jt-manage-mapper</name>
  <url>http://maven.apache.org</url>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
  	<dependency>
  		<groupId>com.jt.manage</groupId>
  		<artifactId>jt-manage-pojo</artifactId>
  		<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  </dependencies>
</project>
 

jt-manage-service（同樣操作，建立maven工程）

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.jt.manage</groupId>
    <artifactId>jt-manage</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <groupId>com.jt.manage</groupId>
  <artifactId>jt-manage-service</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>jt-manage-service</name>
  <url>http://maven.apache.org</url>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 </properties>
  <dependencies>
  	<dependency>
  		<groupId>com.jt.manage</groupId>
  		<artifactId>jt-manage-mapper</artifactId>
  		<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  </dependencies>
</project>

jt-manage-web（同樣操作，不同的是建立的是web-maven工程）

1）和上面工程不同的是，選擇web工程。

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.jt.manage</groupId>
    <artifactId>jt-manage</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</parent>
  <groupId>com.jt.manage</groupId>
  <artifactId>jt-manage-web</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>
  <name>jt-manage-web Maven Webapp</name>
  <url>http://maven.apache.org</url>


  <dependencies>
  	<dependency>
  		<groupId>com.jt.manage</groupId>
  		<artifactId>jt-manage-service</artifactId>
  		<version>0.0.1-SNAPSHOT</version>
  	</dependency>
  </dependencies>
  
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<version>2.2</version>
				<configuration>
					<port>8081</port>
					<path>/</path>
				</configuration>
			</plugin>
		</plugins>
	</build>  
</project>

最終父工程jt-manage中的modules增加了

<modules>
	<module>jt-manage-pojo</module>
    <module>jt-manage-mapper</module>
    <module>jt-manage-service</module>
    <module>jt-manage-web</module>
  </modules>

子工程的依賴關係

pojo依賴common：

<dependency>
  	<groupId>com.jt.common</groupId>
  	<artifactId>jt-common</artifactId>
  	<version>0.0.1-SNAPSHOT</version>
</dependency>

mapper依賴pojo：

<dependency>
	<groupId>com.jt.manage</groupId>
	<artifactId>jt-manage-pojo</artifactId>
	<version>1.0.0-SNAPSHOT</version>
</dependency>

serivce依賴mapper：

<dependency>
	<groupId>com.jt.manage</groupId>
	<artifactId>jt-manage-mapper</artifactId>
	<version>1.0.0-SNAPSHOT</version>
</dependency>

web依賴service：

<dependency>
	 <groupId>com.jt.manage</groupId>
	 <artifactId>jt-manage-service</artifactId>
	 <version>1.0.0-SNAPSHOT</version>
</dependency>

注意，每個工程都需要釋出到Maven本地倉庫中，否則依賴將出錯，安裝如下圖：

必須按照順序依次進行此操作。
