命令行快速找出class文件所在的jar包

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

示例输出：

D:\shared\xsql>for %i in (dir/b/s *.jar) do 7z l %i |findstr XDatabase.classD:\shared\xsql>7z l dir/b/s   | findstr XDatabase.classD:\shared\xsql>7z l db2jcc.jar   | findstr XDatabase.classD:\shared\xsql>7z l db2jcc_license_cu.jar   | findstr XDatabase.classD:\shared\xsql>7z l jconn3.jar   | findstr XDatabase.classD:\shared\xsql>7z l jodbc.jar   | findstr XDatabase.classD:\shared\xsql>7z l jTDS3.jar   | findstr XDatabase.classD:\shared\xsql>7z l mlscript.jar   | findstr XDatabase.classD:\shared\xsql>7z l msbase.jar   | findstr XDatabase.classD:\shared\xsql>7z l mssqlserver.jar   | findstr XDatabase.classD:\shared\xsql>7z l msutil.jar   | findstr XDatabase.classD:\shared\xsql>7z l mysql-connector-java-5.1.6-bin.jar   | findstr XDatabase.classD:\shared\xsql>7z l ojdbc14.jar   | findstr XDatabase.classD:\shared\xsql>7z l postgresql-8.4-701.jdbc4.jar   | findstr XDatabase.classD:\shared\xsql>7z l sqlite.jar   | findstr XDatabase.classD:\shared\xsql>7z l sqlitejdbc-v056-zentus.jar   | findstr XDatabase.classD:\shared\xsql>7z l sqljdbc.jar   | findstr XDatabase.classD:\shared\xsql>7z l ULjDatabaseTransfer.jar   | findstr XDatabase.classD:\shared\xsql>7z l UltraLiteJ.jar   | findstr XDatabase.classD:\shared\xsql>7z l UltraLiteJ12.jar   | findstr XDatabase.class[b]D:\shared\xsql>7z l xsql.jar   | findstr XDatabase.class2010-12-24 21:05:40 .....        30863        14443  [/b]com\sean\db\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 offSETLOCALset WHICH_CLASS=%1echo 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：
echo "Usage: $0 class_name jar_path_1 [jar_path2]...[jar_pathn]"
exit 1
fi
#class to be found
CLASS=$1

shift 1
for JAR in $*
do
if [ -d ${JAR} ]
then
JARS=`find ${JAR} -name "*.jar"`
else
JARS=${JAR}
fi

FOUND=""
for EACHJAR in ${JARS}
do
FOUND=$(jar tf ${EACHJAR}|grep ${CLASS})
if [ "x${FOUND}" != "x" ]
then
echo "-----------------------------------"
echo ${CLASS} was found in ${EACHJAR}
echo ${FOUND}|tr " " "\n"|grep -v .classPK
fi
done
done
exit 0
echo "Usage: $0 class_name jar_path_1 [jar_path2]...[jar_pathn]"
exit 1
fi
#class to be found
CLASS=$1

shift 1
for JAR in $*
do
if [ -d ${JAR} ]
then
JARS=`find ${JAR} -name "*.jar"`
else
JARS=${JAR}
fi

FOUND=""
for EACHJAR in ${JARS}
do
FOUND=$(jar tf ${EACHJAR}|grep ${CLASS})
if [ "x${FOUND}" != "x" ]
then
echo "-----------------------------------"
echo ${CLASS} was found in ${EACHJAR}
echo ${FOUND}|tr " " "\n"|grep -v .classPK
fi
done
done
exit 0

曾经考虑过使用jar命令，无奈运行速度实在太慢了，跟7z没法比。
