基于SVN提交历史筛选作者并修改文件内容

笔者最近开发的项目中，是通过SVN做为版本管理工具的，因为需要创建的文件太多，所以有许多文件是在原有文件基础上拷贝过来修改的，这里就涉及到一个问题，原有文件中注释里填的JAVA类名、作者工号、创建时间等，都是需要修改成我自己的，因为文件太多，一个个修改起来太麻烦，所以我写了一个程序来自动扫描这些文件并替换文件中指定注释。

1.需要从项目中筛选出我创建的文件：
这个就通过SVN提交日志来筛选吧，因为SVN提交历史中有提交人的工号，我通过筛选自己的工号就可以查出哪些文件是我的（当然需要注意的一点就是如果你改了别人的文件并提交，也会被筛选出，所以你可以对筛选出的文件做进一步的筛选，我这里就通过类名命名规则又筛了一次）。
查询SVN提交历史需要使用svnkit包，svnkit下载路径：svnkit
这部分的实现类在后面提到的CheckSVNComment类中。
２.替换文件中信息
文件筛选出来后，就需要检查该文件中注释信息是否正确，如果不正确的话，就需要替换成指定信息，我这里对注释中的文件名，作者，创建时间进行了检查（创建时间必须是有作者不正确的前提下才会检查）。
这部分的实现类在后面提到的ModifyFileContent类中。
