java 获取 jar 包内文件列表

   获取 jar 包内文件列表，使用 JarFile。下面是我的测试类：

package com.zd.test1;

import java.io.File;
import java.io.FileFilter;
import java.io.IOException;
import java.util.Enumeration;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class TestJarFile {

public static void main(String[] args) throws IOException {
File path = new File(System.getProperty("user.dir") + "/" + "zd" + "/");

File[] jarFiles =  path.listFiles(new FileFilter() {

@Override
public boolean accept(File file) {
return file.getName().toUpperCase().endsWith("JAR");
}
});

JarFile jf = null;
for(File fileTemp : jarFiles){
jf = new JarFile(fileTemp);
Enumeration<JarEntry> enume = jf.entries();
while(enume.hasMoreElements()){
JarEntry element = enume.nextElement();
String name = element.getName();
if(name.toUpperCase().endsWith(".CLASS")){
System.out.println(name);
}
}
}
}

}

输出结果如下：
