史上最全的maven的pom.xml文件详解：

下面的节点有不理解是啥意思的可以到上面链接的文章里搜索对照
打开父项目的pom.xml
整个pom文件太大，我们一点一点添吧，不然很乱，很难讲清楚。
1、初始状态
<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>tsglxt</groupId>
<artifactId>tsglxt</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- 打包方式 -->
<packaging>pom</packaging> <!-- 引入的模块 -->
<modules>
<module>tsglxt-common</module>
<module>tsglxt-dao</module>
<module>tsglxt-service</module>
<module>tsglxt-web</module>
</modules>
</project>
2、添加节点
<?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>tsglxt</groupId>
<artifactId>tsglxt</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging> <!-- 以值替代名称，Properties可以在整个POM中使用，也可以作为触发条件。格式是<name>value</name>。 -->
<properties> </properties> <!-- 构建项目需要的信息 -->
<build> </build> <!-- 继承自该项目的所有子项目的默认依赖信息。这部分的依赖信息不会被立即解析,而是当子项目声明一个依赖（必须描述group ID和artifact ID信息），如果group ID和artifact ID以外的一些信息没有描述，则通过group ID和artifact ID匹配到这里的依赖，并使用这里的依赖信息。 -->
<dependencyManagement>
<!-- 项目引入插件所需要的额外依赖 -->
<dependencies> </dependencies>
</dependencyManagement> <!-- 项目引入插件所需要的额外依赖 -->
<dependencies> </dependencies> <!-- 项目分发信息，在执行mvn deploy后表示要发布的位置。有了这些信息就可以把网站部署到远程服务器或者把构件部署到远程仓库。 -->
<distributionManagement> </distributionManagement> <modules>
<module>tsglxt-common</module>
<module>tsglxt-dao</module>
<module>tsglxt-service</module>
<module>tsglxt-web</module>
</modules>
</project>

3、添加Maven plugin （看准第一个节点，然后在2中找到对应的节点，把里边的内容复制过去。后面的步骤也是这样）
<properties>
<!-- Maven plugin -->
<maven-source-plugin.version>2.0.3</maven-source-plugin.version>

<maven-version-plugin.version>2.1</maven-version-plugin.version>
<maven-jar-plugin.version>2.3.2</maven-jar-plugin.version>
<maven-archetype-plugin.version>2.2</maven-archetype-plugin.version> </properties> <build>
<pluginManagement>

7、根据各自项目需要，自行添加别的maven配置信息
打开dao层的pom.xml
dao层需要引用common层的po、vo等实体
<dependencies>
<dependency>
<groupId>tsglxt</groupId>
<artifactId>tsglxt-common</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
打开service层的pom.xml
service层需要引用dao层和common层，因为dao层引入过common层的xml，引入dao层后common层也自动引入了
<dependencies>
<dependency>
<groupId>tsglxt</groupId>
<artifactId>tsglxt-dao</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
打开web层的pom.xml
web层（action层）需要引用service层，同上同理
web层还需要引入jstl等jar包……
需要添加一个build节点，描述项目相关的所有资源路径列表。
<dependencies>
<dependency>
<groupId>tsglxt</groupId>
<artifactId>tsglxt-service</artifactId>
<version>${project.version}</version>
</dependency> <dependency>
<groupId>nl.captcha</groupId>
<artifactId>simplecaptcha</artifactId>
<version>1.2.1</version>
</dependency> <dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>taglibs</groupId>
<artifactId>standard</artifactId>
<version>1.1.2</version>
</dependency>
<dependency>
<groupId>org.tuckey</groupId>
<artifactId>urlrewritefilter</artifactId>
<version>4.0.3</version>
</dependency>
</dependencies> <build>
<!-- 产生的构件的文件名，默认值是${artifactId}-${version} -->
<finalName>tsglxt-web</finalName>
<!-- 这个元素描述了项目相关的所有资源路径列表，例如和项目相关的属性文件，这些资源被包含在最终的打包文件里 -->
<resources>
<!-- 这个元素描述了项目相关或测试相关的所有资源路径 -->
<resource>
<!-- 描述存放资源的目录，该路径相对POM路径 -->
<directory>src/main/resources</directory>
<!-- 是否使用参数值代替参数名。参数值取自properties元素或者文件里配置的属性，文件在filters元素里列出 -->
<filtering>true</filtering>
</resource>
</resources>
</build>
到这里pom.xml就配完了，但是你会发现web层的pom.xml有一个报错：
web.xml is missing and <failOnMissingWebXml> is set to true
意思很显然，没有找到web.xml嘛。我们搭建的项目里并没有自动生成这个文件。别慌，后面的章节有讲到这个。
还有一点，通过maven搭建项目，就不需要自己去官网下载jar包了，前面第一章就没啥用了，第二章的jar包不再是手动添加到项目里，而是通过pom.xml的配置直接引用maven仓库里的jar包。
