創建maven聚合工程

整體架構圖

taotao-parent :父工程，打包方式pom,管理jar包的版本號。

　　|　　　　　　項目中所有工程都應該繼承父工程。

　　|--taotao-common : 通用的工具類，打包方式 jar

　　|--taotao-manager : 服務層工程。聚合工程。打包方式 pom

　　　　|--taotao-pojo : 打包方式 jar

　　　　|--taotao-dao :  打包方式 jar

　　　　|--taotao-interface :  打包方式 jar

　　　　|--taotao-service :  打包方式 jar

　　　　|--taotao-web :  打包方式 war

 

1.新建父工程

新建maven父項目(用來管理jar包版本)，使子系統使用同一個版本的jar包。

File-》New-》Other-》Maven Project，打包方式選pom

 

<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">

<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>taotao-common</module>
<module>taotao-manager</module>
</modules>

<!-- 集中定義依賴版本號 -->

<mybatis-paginator.version>1.2.17</mybatis-paginator.version>
<pagehelper.version>5.1.8</pagehelper.version>
<mysql-connector-java.version>8.0.14</mysql-connector-java.version>

</properties>

<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>
</plugins>
</pluginManagement>
</build>
</project>

2.新建子工具工程

創建common通用工具類項目，父類為剛才創建的項目，打包方式為jar

<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>
<groupId>com.taotao</groupId>
<artifactId>taotao-parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>taotao-common</artifactId>

<!-- 依賴的jar包 -->
<dependencies>
<!-- Jackson Json處理工具包 -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson-databind.version}</version>
</dependency>
<!-- httpclient -->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>${httpclient.version}</version>
</dependency>
<!-- 單元測試 -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>
<!-- 日志處理 -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>${slf4j-log4j12.version}</version>
</dependency>
</dependencies>
</project>

3.新建服務工程（POM）

創建聚合項目，聚合pojo、dao、interface、service等子項目。打包方式為pom，父項目為剛才創建的jar包版本管理項目。

<?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>
<groupId>com.taotao</groupId>
<artifactId>taotao-parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>taotao-manager</artifactId>
<packaging>pom</packaging>
<modules>
<module>taotao-pojo</module>
<module>taotao-dao</module>
<module>taotao-interface</module>
<module>taotao-service</module>
<module>taotao-web</module>
</modules>
<dependencies>
<!--依賴taotao-common通用工具類工程 -->
<dependency>
<groupId>com.taotao</groupId>
<artifactId>taotao-common</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
<!-- 配置tomcat插件 -->
<build>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path> <!-- tomcat項目路徑 -->
<port>8080</port> <!-- tomcat端口 -->
</configuration>
</plugin>
</plugins>
</build>
</project>

 

4.創建服務層的子項目

右擊步驟3創建的聚合項目，選擇Maven Module，輸入Module項目創建子項目，next選擇jar打包方式，用相同的方法創建pojo、dao、interface、service、web（這個打包方式選擇war）子項目。

5.子項目依賴關系

 dao和interface依賴pojo，service依賴dao和interface，web依賴service。

 其中taotao-dao的pom文件為

<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">

6.右擊manager聚合項目Run as-》Maven build-》clean tomcat7:run

7.如果發現執行失敗，且maven倉庫中找不到父項目和common項目，此時需要右擊這兩個項目Run as-》Maven Install即可加載到本地倉庫中。

8.執行成功，瀏覽器輸入地址即可查看
