java 反编译 行号对齐 decompiler如何去掉行号

有没有感觉你用java反编译工具jd-gui.exe后，得到源码是行号对不上的，如下面，这样的源码在debug起来很不方便，根本对不上，没有调试的价值

/*     */ import org.dom4j.io.SAXReader;/*     */ /*     */ public class ForHttpXMLAction extends HostAccessAction/*     */ {/*  75 */   private String sendHeadFormatName = null;/*     */ /*  80 */   private String sendFormatName = "httpSendFormat";/*     */ /*  85 */   private String receiveFormatName = "httpReceiveFormat";/*     */ /*  90 */   private String receiveHeadFormatName = null;/*     */ /*  95 */   private int timeOut = 0;/*     */ /* 100 */   private String serviceName = null;/*     */ /* 105 */   private String urlEncoding = "ISO8859-1";/*     */ /* 110 */   private String encoding = "GBK";/*     */ /* 115 */   private String inputFeild = null;/*     */ /* 120 */   private String outputFeild = null;/*     */ /* 125 */   private String chanlTradNo = null;/*     */ 

但是幸好的是，上面的行号的注释，比如这样“/* 115* /”

为了方便用eclipse的调试debug,我写了一个程序，来格式式行号，使上面的行号按照注释的对齐，这样调试起来特别方便

你只需要把jd-gui.exe反编译生成的源码目录传到main方法即可，下面代码就会生成一个与源代码平级同名+bak的文件，话不多说，直接看代码
