给我一个maven结构的war包，反编译成项目并成功运行起来

开发工具eclipse，idea，反编译工具jq-gui

1.用eclipse创建一个maven结构的web项目

将第一项勾选，跳过选择maven结构类型，下一步的jar包类型一定要选择war包类型，其他自定义，

标准的maven结构，webapp里面的文件可以自己建。

pom文件以下配置注意两点，maven依赖包如果是私有包必须通过maven打包命令打进本地仓库再引用。打本地仓命令：mvn install:install-file -Dfile=E:\内网通文件\杜青\WEB-INF\lib\proxool-cglib.jar -DgroupId=proxool -DartifactId=proxool-cglib -Dversion=0.9.1 -Dpackaging=jar

解决Cannot change version of project facet Dynamic web module to 2.5
这里写链接内容

最近做的一个项目中运用到了连接池技术，可能我们大家比较熟悉的开源连接池有dbcp,c3p0,proxool。对这三种连接池来说，从性能和出错率来说，proxool稍微比前两种好些。今天我主要简单的讲述一下proxool，我在项目中成功的配置和源码。

    第一步：首先去http://proxool.sourceforge.net/下载一个proxool.jar文件了，我用的是proxool-0.9.0RC3.jar,现在最新版本是proxool-0.9.1.jar,我在用这个JAR包时,老是报如下错误: 

严重: Servlet.service() for servlet action threw exception
java.lang.NoClassDefFoundError: org/logicalcobwebs/cglib/proxy/Callback
at org.logicalcobwebs.proxool.ConnectionPool.getConnection(ConnectionPool.java:261)
at org.logicalcobwebs.proxool.ProxoolDriver.connect(ProxoolDriver.java:89)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)

最后换用proxool-0.9.0RC3.jar无此问题,哪们知道解决办法的话,请留言.
.除了他们的查看监控台的页面有变化，其他的变化不是太大。

换了jar包之后，CallBack类就可以找到了。以上就是在整个过程中遇到的比较难的问题，备忘下。
