一个weblogic自动打补丁自动卸载冲突补丁的脚本，拖拖踏踏写了100多行，总算是勉强可以用了，对于删除多级冲突（不知道weblogic是不是有这种多级依赖，目前遇到的是一级冲突，冲突两个旧补丁）没有真实测试环境，写的时候是考虑的，不过又是冲突列表又要按顺序删除，写的自己都不太确定了，加上没多级冲突的测试环境，所以遇上复杂的情况不保证可以完成操作，不过应付一下简单的还是够了
脚本运行环境linux + python2（windows的里面有些路径要修改/ 为\，应该也是可以的），程序中写死了补丁的压缩文件名和新补丁的ID，修改为参数提供会适用性更强，但是本次只针对这个补丁，所以暂时不修改这些
脚本运行需提供两个参数：MW_HOME 和 WL_HOME
例如：

python dufg.py /servyouapp/bea/ /servyouapp/bea/wlserver_10.3/

脚本代码如下:

脚本的健壮性比较差，很多异常处理没有做，只是勉强可以用而已，记录，有需求再改进
