Jad调用参数如下：
Usage: jad [option(s)] <filename(s)>
Options: -a - generate JVM instructions as comments (annotate)
-af - output fully qualified names when annotating
-b - generate redundant braces (braces)
-clear - clear all prefixes, including the default ones
-d <dir> - directory for output files
-dead - try to decompile dead parts of code (if there are any)
-dis - disassembler only (disassembler)
-f - generate fully qualified names (fullnames)
-ff - output fields before methods (fieldsfirst)
-i - print default initializers for fields (definits)
-l<num> - split strings into pieces of max <num> chars (splitstr)
-lnc - output original line numbers as comments (lnc)
-lradix<num>- display long integers using the specified radix
-nl - split strings on newline characters (splitstr)
-noconv - don't convert Java identifiers into valid ones (noconv)
-nocast - don't generate auxiliary casts
-noclass - don't convert .class operators
-nocode - don't generate the source code for methods
-noctor - suppress the empty constructors
-nodos - turn off check for class files written in DOS mode
-nofd - don't disambiguate fields with the same names (nofldis)
-noinner - turn off the support of inner classes
-nolvt - ignore Local Variable Table entries (nolvt)
-nonlb - don't insert a newline before opening brace (nonlb)
-o - overwrite output files without confirmation
-p - send all output to STDOUT (for piping)
-pa <pfx>- prefix for all packages in generated source files
-pc <pfx>- prefix for classes with numerical names (default: _cls)
-pe <pfx>- prefix for unused exception names (default: _ex)
-pf <pfx>- prefix for fields with numerical names (default: _fld)
-pi<num> - pack imports into one line using .* (packimports)
-pl <pfx>- prefix for locals with numerical names (default: _lcl)
-pm <pfx>- prefix for methods with numerical names (default: _mth)
-pp <pfx>- prefix for method parms with numerical names (default:_prm)
-pv<num> - pack fields with the same types into one line (packfields)
-r - restore package directory structure
-radix<num>- display integers using the specified radix (8, 10, or 16)
-s <ext> - output file extension (default: .jad)
-safe - generate additional casts to disambiguate methods/fields
-space - output space between keyword (if, while, etc) and expression
-stat - show the total number of processed classes/methods/fields
-t<num> - use <num> spaces for indentation (default: 4)
-t - use tabs instead of spaces for indentation
-v - show method names while decompiling
-8 - convert Unicode strings into ANSI strings (ansi)
-& - redirect STDERR to STDOUT部分参数解释如下：
-8: 把Unicode编码的字符转换成ASCII输出，这样程序中的中文就会原样输出，而不是令人费解的uxxxx这种形式
-nl: 把字符串按照
切分输出，这样很长的字符串也不至于都放在一行，增强了可读性。

-ff: 把数据成员放在方法之前，这样就符合大家写程序的习惯了
-space: 在if, while等关键字和表达式之间加入空格，这是java的良好编程风格
-nonlb: 不在开大括号（也就是左大括号）前加回车，这是大部分java程序员的习惯风格，大家可以根据自己的习惯选用
经过这样的配置，jad输出的java代码几乎跟手写的没有什么两样
具体我的示例如下：
在DOS下进入jad目录后，敲入：
D:\My Document\download\jad>jad -d D:\java -ff -nl -space -8 -nonlb -r -s java E:\vbao\WEB-INF\classes\com\sztelecom\vbao\**\*.class
