1.下载反编译工具jad（下面提供下载）
将下载下来的jadstar158.zip解压缩，将jad.exe文件放入jdk安装目录下
如：D:\Program Files\Java\jdk1.6.0_20\bin?
?
2.下载eclipse反编译插件net.sf.jadclipse_3.3.0.jar（下面提供下载）
?
3.将net.sf.jadclipse_3.3.0.jar?放入MyEclipse安装目录下，
?如?：安装目录\Genuitec\dropins下?没有dropins，新建之，然后在dropins中新建features文件夹和plugins文件夹，将net.sf.jadclipse_3.3.0.jar拷贝到plugins中，然后新建java工程，运行以下代码（替换其中最后的代码，你电脑反编译插件所在的实际位置）：
? ?import java.io.File; import java.util.ArrayList; import java.util.List; /** * MyEclipse9 插件配置代码生成器 * * */ public class CreatePluginsConfig { public CreatePluginsConfig() { } public void print(String path) { List<String> list = getFileList(path); if (list == null) { return; } int length = list.size(); for (int i = 0; i < length; i++) { String result = ""; String thePath = getFormatPath(getString(list.get(i))); File file = new File(thePath); if (file.isDirectory()) { String fileName = file.getName(); if (fileName.indexOf("_") < 0) { print(thePath); continue; } String[] filenames = fileName.split("_"); String filename1 = filenames[0]; String filename2 = filenames[1]; result = filename1 + "," + filename2 + ",file:/" + path + "\\" + fileName + "\\,4,false"; System.out.println(result); } else if (file.isFile()) { String fileName = file.getName(); if (fileName.indexOf("_") < 0) { continue; } int last = fileName.lastIndexOf("_");// 最后一个下划线的位置 String filename1 = fileName.substring(0, last); String filename2 = fileName.substring(last + 1, fileName .length() - 4); result = filename1 + "," + filename2 + ",file:/" + path + "\\" + fileName + ",4,false"; System.out.println(result); } } } public List<String> getFileList(String path) { path = getFormatPath(path); path = path + "/"; File filePath = new File(path); if (!filePath.isDirectory()) { return null; } String[] filelist = filePath.list(); List<String> filelistFilter = new ArrayList<String>(); for (int i = 0; i < filelist.length; i++) { String tempfilename = getFormatPath(path + filelist[i]); filelistFilter.add(tempfilename); } return filelistFilter; } public String getString(Object object) { if (object == null) { return ""; } return String.valueOf(object); } public String getFormatPath(String path) { path = path.replaceAll("\\\\", "/"); path = path.replaceAll("//", "/"); return path; } public static void main(String[] args) { /*替换成你的插件的安装目录*/ String plugin = "C:\\Users\\Administrator\\AppData\\Local\\Genuitec\\dropins"; new CreatePluginsConfig().print(plugin); } }
?
4.重启MyEclipse,配置 jadclipse ?
?
在Eclipse?的Windows—>?Perferences—>General->Editors->File?Associations?中修改“*.class”默认关联的编辑器为“JadClipse?Class?File?Viewer”。如果没有*.class，则点击“add"增加一个。
?
安装设置完毕，可以双击class文件。
