介绍一个好用的工具类库commons-beanutils
转自：http://www.blogjava.net/rongxh7/archive/2009/06/22/283566.html
<div class="post" style="background-color: white; color: #4b4b4b; font-size: 13px; padding: 20px; border: 1px dotted #8b8d72;">commons-beanutils.jar可以到Apache官网的commons子项目下找到它，或者，在Struts2,Spring的下载包中也能看到它的影子。单独使用时，要多引进一个commons-logging.jar，这个包也是非常见的，可在有commons-beanutils.jar的地方找到它。
好，我们来测试一下，怎么使用这个类库中的两个常用类及它的常用方法。首先，写一个POJO类，代码如下：
<div style="padding-bottom: 4px; background-color: #eeeeee; padding-left: 4px; width: 1006px; padding-right: 5px; font-size: 13px; padding-top: 4px; border: 1px solid #cccccc;">http://www.blogjava.net/Images/OutliningIndicators/None.gifpackage rong.propertyUtils;
