【整理】将javaWeb工程转成Maven工程

之前碰到过很多javaWeb工程，直接使用lib文件夹管理jar包，缺点多多，jar包版本混乱，不堪其扰，故创建pom、整理成maven管理。

而且这种工程打包基本都是使用eclipse等开发工具打包，不方便使用自动构建工具，使用maven管理可以使用它的打包工具。

1. 创建pom文件，将配置信息和依赖jar包信息写入其中
   jar包相关信息可以去该网址去查找。

2. 创建打包文件package.xml，将打包策略写入其中

 <assembly>
    <id>${project.artifactId}-assembly-${project.version}id>
    
    
    
    <includeBaseDirectory>falseincludeBaseDirectory>

    formats>
    <fileSets>

            <directory>${project.build.outputDirectory}directory>
            <outputDirectory>WEB-INF/classesoutputDirectory>
        fileSet>
        
        <fileSet>
            <directory>${project.basedir}/src/main/webappdirectory>
            <outputDirectory>/outputDirectory>
