for %i in (dir/b/s *.jar) do 7z l %i | findstr XDatabase.class

上述命令弄得还是比较粗糙，干脆写一个批处理findclass.bat
内容如下：

@echo off
SETLOCAL

set WHICH_CLASS=%1
echo WHICH_CLASS=%WHICH_CLASS%

for /F %%i in ('dir /A:-D /S /B *.jar') do 7z l %%i | findstr %WHICH_CLASS% && echo %WHICH_CLASS% found in: "%%i"
echo "Finished class finding..."
echo "======================================"
ENDLOCAL

这样想查找一个class就很容易了：

引用

findclass com\\sybase\\afx\\util\\StringUtil.class
WHICH_CLASS=com\\sybase\\afx\\util\\StringUtil.class
2012-02-27 13:14:36 .....        15230         5915  com\sybase\afx\util\StringUtil.class
com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-client.jar"
2012-02-27 13:14:36 .....        15230         5915  com\sybase\afx\util\StringUtil.class
com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-server-rt.jar"
"Finished class finding..."
"======================================"

其实，最想弄的，是把7z的源码稍作修改，直接让7z l <文件> | findstr 直接同时输出文件名，那是最好的办法。
