終于有時間搞java了，今天使用IDEA基于maven搭建了多模塊聚合工程，經過了多番嘗試，終于成功啦！

注意：這里是在原作者的基礎上改進的版本，原作者的版本的pom依賴存在問題，所以，這里的依賴全部是我自己的依賴，圖片按照這個來完全沒有問題！

一.工程目錄

下面是搭建之后的目錄

這里寫圖片描述

先看一下目錄關系

taotao-parent（父工程管理jar包的版本）

|--taotao-common（把通用的工具類打包）

|--taotao-manager（繼承父工程）

??|-taotao-manager-pojo|-taotao-manager-dao|-taotao-manager-service|-taotao-manager-web（war包）

taotao-parent 為項目的父工程，用來管理jar包及版本

taotao-common為通用工程，繼承父工程，就是把通用的工具類打包

taotao-manager為開發工程，同樣繼承父工程

其中，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service和taotao-manager-web均為開發工程的一個子模塊，依賴于開發工程taotao-manager

前3個子模塊打成jar包，taotao-manager-web打成war包

二.創建工程

1.先創建一個空工程，步驟如下：
File——>new——>project

這里寫圖片描述

選擇Empty——>next

這里寫圖片描述

填寫工程名稱和位置，點擊finnish，完成了空工程的創建

這里寫圖片描述

2.創建父工程 taotao-parent，步驟如下：

File——>New——>Module

這里寫圖片描述

點maven，勾選archetype，選quickstart這項，然后Next下一步

這里寫圖片描述

填寫GroupId，一般為組織名稱；填寫ArtifactId，為項目名稱

這里寫圖片描述

選擇本地maven目錄及maven配置文件

這里寫圖片描述

填寫項目名稱及位置，點Finish，父工程創建完成

這里寫圖片描述

等待生成pom文件，修改打包方式為pom，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"><modelVersion>4.0.0</modelVersion><groupId>com.chinapost</groupId><artifactId>post-parent</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><!--?集中定義依賴版本號?--><properties><junit.version>4.10</junit.version><spring.version>4.1.3.RELEASE</spring.version><mybatis.version>3.2.8</mybatis.version><mybatis.spring.version>1.2.2</mybatis.spring.version><mybatis.paginator.version>1.2.15</mybatis.paginator.version><mysql.version>5.1.32</mysql.version><slf4j.version>1.6.4</slf4j.version><jackson.version>2.4.2</jackson.version><druid.version>1.0.9</druid.version><httpclient.version>4.3.5</httpclient.version><jstl.version>1.2</jstl.version><servlet-api.version>2.5</servlet-api.version><jsp-api.version>2.0</jsp-api.version><joda-time.version>2.5</joda-time.version><commons-lang3.version>3.3.2</commons-lang3.version><commons-io.version>1.3.2</commons-io.version></properties><dependencyManagement><dependencies><!--?單元測試?--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><!--?Spring?--><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><!--?Mybatis?--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis.spring.version}</version></dependency><!--?分頁助手?--><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId><version>3.7.5</version></dependency><dependency><groupId>com.github.jsqlparser</groupId><artifactId>jsqlparser</artifactId><version>0.9.1</version></dependency><!--?通用Mapper?--><dependency><groupId>com.github.abel533</groupId><artifactId>mapper</artifactId><version>2.3.4</version></dependency><!--?MySql?--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!--?Jackson?Json處理工具包?--><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>${jackson.version}</version></dependency><!--?連接池?--><dependency><groupId>com.jolbox</groupId><artifactId>bonecp-spring</artifactId><version>0.8.0.RELEASE</version></dependency><!--?httpclient?--><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>${httpclient.version}</version></dependency><!--?JSP相關?--><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>${jstl.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>${servlet-api.version}</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><version>${jsp-api.version}</version><scope>provided</scope></dependency><!--?時間操作組件?--><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId><version>${joda-time.version}</version></dependency><!--?Apache工具組件?--><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>${commons-lang3.version}</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-io</artifactId><version>${commons-io.version}</version></dependency></dependencies></dependencyManagement><build><finalName>${project.artifactId}</finalName><plugins><!--?資源文件拷貝插件?--><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-resources-plugin</artifactId><version>2.7</version><configuration><encoding>UTF-8</encoding></configuration></plugin><!--?java編譯插件?--><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.2</version><configuration><source>1.7</source><target>1.7</target><encoding>UTF-8</encoding></configuration></plugin></plugins><pluginManagement><plugins><!--?配置Tomcat插件?--><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version></plugin></plugins></plug

</project>

3.創建通用工程taotao-common

File——>New——>Module

這里寫圖片描述

點maven后直接next下一步

這里寫圖片描述

繼承taotao-parent,填寫ArtifactId,然后next下一步

這里寫圖片描述

填寫通用模塊名稱，點finish，通用模塊創建完成

這里寫圖片描述

開發模塊taotao-manager與通用模塊創建方式一致

taotao-common的pom.xml

<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.chinapost</groupId><artifactId>post-parent</artifactId><version>1.0-SNAPSHOT</version></parent><groupId>com.chinapost</groupId><artifactId>post-common</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><dependencies><!--?Jackson?Json處理工具包?--><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>${jackson.version}</version></dependency><!--?時間操作組件?--><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId><version>${joda-time.version}</version></dependency><!--?Apache工具組件?--><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>${commons-lang3.version}</version></dependency></dependencies> </project>

taotao-manager的pom.xml

<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.chinapost</groupId><artifactId>post-parent</artifactId><version>1.0-SNAPSHOT</version></parent><groupId>com.chinapost</groupId><artifactId>post-manager</artifactId><version>1.0-SNAPSHOT</version><packaging>pom</packaging><dependencies><dependency><groupId>com.chinapost</groupId><artifactId>post-common</artifactId><version>1.0-SNAPSHOT</version></dependency><!--?單元測試?--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></dependency><!--?Apache工具組件?--><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>${commons-lang3.version}</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-io</artifactId><version>${commons-io.version}</version></dependency></dependencies><build><plugins><!--?配置Tomcat插件?--><plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><configuration><port>8999</port><path>/</path></configuration></plugin></plugins></build><modules><module>post-manager-pojo</module><module>post-manager-dao</module><module>post-manager-service</module><module>post-manager-web</module></modules> </project>

4.創建開發模塊下的子模塊，分兩類介紹，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service創建方式一樣，taotao-manager-web的創建有點差別

1）以taotao-manager-pojo為例

File——>new——>module

這里寫圖片描述

選maven——>勾選archetype——>選quickstart這項——>點next

這里寫圖片描述

繼承taotao-manager，填寫ArtifactId

這里寫圖片描述

這里注意改寫路徑，點finish，一個子模塊創建完成

這里寫圖片描述

taotao-manager-pojo的pom.xml

<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.chinapost</groupId><artifactId>post-manager</artifactId><version>1.0-SNAPSHOT</version></parent><groupId>com.chinapost</groupId><artifactId>post-manager-pojo</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><dependencies><dependency><groupId>com.chinapost</groupId><artifactId>post-common</artifactId><version>1.0-SNAPSHOT</version></dependency><dependency><groupId>javax.persistence</groupId><artifactId>persistence-api</artifactId><version>1.0</version></dependency></dependencies> </project>

taotao-manager-dao的pom.xml

<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>post-manager</artifactId><groupId>com.chinapost</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>post-manager-dao</artifactId><packaging>jar</packaging><name>post-manager-dao</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>com.chinapost</groupId><artifactId>post-manager-pojo</artifactId><version>1.0-SNAPSHOT</version></dependency><!--?Mybatis?--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId></dependency><!--?通用Mapper?--><dependency><groupId>com.github.abel533</groupId><artifactId>mapper</artifactId></dependency></dependencies> </project>??

taotao-manager-service的pom.xml

<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>post-manager</artifactId><groupId>com.chinapost</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>post-manager-service</artifactId><packaging>jar</packaging><name>post-manager-service</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>com.chinapost</groupId><artifactId>post-manager-dao</artifactId><version>1.0-SNAPSHOT</version></dependency><!--?Spring?--><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId></dependency><!--?分頁助手?--><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId></dependency><dependency><groupId>com.github.jsqlparser</groupId><artifactId>jsqlparser</artifactId></dependency></dependencies> </project>??

2）taotao-manager-web創建

同樣File——>New——>Module

只不過這里選擇webapp這項（唯一不同的地方，其他地方類似），點next下一步

這里寫圖片描述

同樣繼承taotao-manager

這里寫圖片描述

同樣需要改寫路徑，點擊finish，taotao-manager-web子模塊創建完成

這里寫圖片描述
taotao-manager-web的pom.xml

<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/maven-v4_0_0.xsd"><parent><artifactId>post-manager</artifactId><groupId>com.chinapost</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>post-manager-web</artifactId><packaging>war</packaging><name>post-manager-web</name><url>http://maven.apache.org</url><!--?添加依賴?--><dependencies><dependency><groupId>com.chinapost</groupId><artifactId>post-manager-service</artifactId><version>1.0-SNAPSHOT</version></dependency><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.1</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId></dependency><!--?MySql?--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><!--?Jackson?Json處理工具包?--><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency><!--?連接池?--><dependency><groupId>com.jolbox</groupId><artifactId>bonecp-spring</artifactId></dependency><!--?JSP相關?--><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><scope>provided</scope></dependency><!--?時間操作組件?--><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId></dependency></dependencies><build><finalName>post-manger-web</finalName></build> </project>

5.接下來運行工程使用：tomcat7:run

右上角Edit Configurations

這里寫圖片描述
選maven
這里寫圖片描述 這里寫圖片描述
需要把taotao-parent等需要安裝的都安裝到本地倉庫。
這里寫圖片描述

最后運行，如下圖所示，就說明跑通了！

這里寫圖片描述

總結：

之前看別人的博客，有選擇portlet項，自己弄死活跑不通。

taotao-parent,taotao-manager-pojo,taotao-manager-dao,taotao-manager-service選擇quickstart那項；

taotao-common，taotao-manager啥都不選；

taotao-manager-web選擇webapp那項。

還要注意打包方式，jar，pom，war
