shell脚本：根据java类名称定位jar包

脚本名称：whichJar.sh

脚本用法：sh whichJar.sh jar目录 java类名,可带包名 [jar包名称]

脚本内容：（如下）

dir=$1
class=$2
name=$3

if [ "$class" = "" -o "$dir" = "" ];then
        echo param error.
        exit -1;
fi

if [ ! -d $dir ];then
        echo directory:$dir, not exists!
        exit -1;
fi

if [ "$name" = "" ];then
        name="jar";
fi

find $dir -name "*${name}*" > tmpjars.txt

while read line
do
        finded=`jar -tvf $line|awk '{gsub("/",".");print $0}'|grep $class`;
        if [ "$finded" != "" ];then
                echo [$line] found [$class]
        fi
done < tmpjars.txt

rm tmpjars.txt

脚本示例：（lib目录下有很多jar包，从中寻找含有StringUtil的jar包）

sh whichJar.sh ./lib/ StringUtil *.jar
[./lib/mysql-connector-java-5.1.22-bin.jar] found [StringUtil]
[./lib/org.springframework.core-3.0.5.RELEASE.jar] found [StringUtil]
[./lib/commons-lang-2.4.jar] found [StringUtil]
