加载jar文件输出class和method

package file

import java.util.jar.JarEntry
import java.util.jar.JarFile

import org.junit.Test;

class ReadJarFileTest01 {

	@Test
	void test001(){
		String default_path = "D:/tools/struts-2.3.16/lib/commons-lang-2.4.jar";
		
		URL[] urls = new URL[1]
		urls[0] = new URL("file:" + default_path)
		ClassLoader parentclassloader = Thread.currentThread().getContextClassLoader()
		//URLClassLoader classLoader = new URLClassLoader(urls, parentclassloader)
		URLClassLoader classLoader = new URLClassLoader(urls)
		Map<String,List<String>> classMethodMap = new LinkedHashMap<String,List<String>>()
		JarFile jarfile = new JarFile(default_path)
		for(JarEntry entry : jarfile.entries()){
			def ename = entry.getName()
			if( ename.contains(".class") ){
				List<String> methods = new ArrayList<String>()
				classMethodMap.put(ename.substring(ename.lastIndexOf("/"), ename.lastIndexOf(".")), methods)
				
				def wholeClassName = ename.replaceAll("/", ".")
				wholeClassName = wholeClassName.substring(0, wholeClassName.lastIndexOf("."))
				//println wholeClassName

					println "================="
					for( p in methodArr ){
						println p
					}
				}
