只需使用FindClassInJars util，这是一个简单的swing程序，但很有用。您可以在http://code.google.com/p/find-class-in-jars/上查看源代码或下载jar文件

当我遇到这个问题时，我不知道有什么实用程序可以做到这一点，所以我写了下面的代码:

public class Main {

    /**
     * 
     */
    private static String CLASS_FILE_TO_FIND =
            "class.to.find.Here";
    private static List<String> foundIn = new LinkedList<String>();

    /**
     * @param args the first argument is the path of the file to search in. The second may be the
     *        class file to find.
     */
    public static void main(String[] args) {
        if (!CLASS_FILE_TO_FIND.endsWith(".class")) {
            CLASS_FILE_TO_FIND = CLASS_FILE_TO_FIND.replace('.', '/') + ".class";
        }
        File start = new File(args[0]);
        if (args.length > 1) {
            CLASS_FILE_TO_FIND = args[1];
        }
        search(start);
        System.out.println("------RESULTS------");
        for (String s : foundIn) {
            System.out.println(s);
        }
    }

    private static void search(File start) {
        try {
            final FileFilter filter = new FileFilter() {

                public boolean accept(File pathname) {
                    return pathname.getName().endsWith(".jar") || pathname.isDirectory();
                }
            };
            for (File f : start.listFiles(filter)) {
                if (f.isDirectory()) {
                    search(f);
                } else {
                    searchJar(f);
                }
            }
        } catch (Exception e) {
            System.err.println("Error at: " + start.getPath() + " " + e.getMessage());
        }
    }

    private static void searchJar(File f) {
        try {
            System.out.println("Searching: " + f.getPath());
            JarFile jar = new JarFile(f);
            ZipEntry e = jar.getEntry(CLASS_FILE_TO_FIND);
            if (e == null) {
                e = jar.getJarEntry(CLASS_FILE_TO_FIND);
                if (e != null) {
                    foundIn.add(f.getPath());
                }
            } else {
                foundIn.add(f.getPath());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

查看JBoss Tattletale;虽然我个人从未使用过，但这似乎是你需要的工具。

User1207523的脚本对我来说很好。这里有一个变体，使用find隐式搜索jar文件，而不是简单的展开;

#!/bin/bash
for i in `find . -name '*.jar'`; do jar -tf "$i" | grep $1 | xargs -I{} echo -e "$i : {}" ; done

使用unzip (zipinfo)的bash脚本解决方案。在Ubuntu 12上测试。

#!/bin/bash

# ./jarwalker.sh "/a/Starting/Path" "aClassName"

IFS=$'\n'
jars=( $( find -P "$1" -type f -name "*.jar" ) )

for jar in ${jars[*]}
    do
        classes=( $( zipinfo -1 ${jar} | awk -F '/' '{print $NF}' | grep .class | awk -F '.' '{print $1}' ) )
        if [ ${#classes[*]} -ge 0 ]; then
            for class in ${classes[*]}
                do
                    if [ ${class} == "$2" ]; then
                        echo "Found in ${jar}"
                    fi
                done
        fi
    done

使用这个. .你可以在类路径..中找到任何文件。保证. .

import java.net.URL;
import java.net.URLClassLoader;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class FileFinder {

    public static void main(String[] args) throws Exception {

        String file = <your file name>;

        ClassLoader cl = ClassLoader.getSystemClassLoader();

        URL[] urls = ((URLClassLoader)cl).getURLs();

        for(URL url: urls){
            listFiles(file, url);
        }
    }

    private static void listFiles(String file, URL url) throws Exception{
        ZipInputStream zip = new ZipInputStream(url.openStream());
          while(true) {
            ZipEntry e = zip.getNextEntry();
            if (e == null)
              break;
            String name = e.getName();
            if (name.endsWith(file)) {
                System.out.println(url.toString() + " -> " + name);
            }
          }
    }

}
