MyEclipse XX安装jad反编译插件

1.下载反编译工具jad，下载地址：http://varaneckas.com/jad/

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：C:\Program Files\Java\jdk1.6.0_20\bin

2.下载eclipse反编译插件net.sf.jadclipse_3.3.0.jar，下载地址：http://prdownloads.sourceforge.net/jadclipse/net.sf.jadclipse_3.3.0.jar?download

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）：

package com.deng;
import java.io.File;
import java.util.ArrayList;
import java.util.List;

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);

                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 = "E:\\Program files\\myeclipse\\eclipse\\plugins";
        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。到这里就可以打开.class文件了。
