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。
