myeclipse反编译插件安装和JAVA反编译工具
很多情况下我们想知道源码，但是又木有源码的情况下怎么办呢？不急，这里提供一个很好的工具，和myeclipse的反编译JAVA插件的安装。安装过程如下：
- 安装插件第一步，不说了
jad -o -dtest -sjava *.class //这个可以编译test目录下所有的class文件
也可以写成这样jad -o -d test -s java *.class
上面只能反编译test目录下的class文件，不能反编译test目录下所有的子目录的class文件。要这种效果，可以使用下面命令
jad -o -r -sjava -dsrc 'tree/**/*.class'
这样就可以反编译tree目录下所有的class文件了。得到的结果放到src目录下。
jad还有下面这些可以用的变量:
-a - annotate the output with JVM bytecodes (default: off)
-af - same as -a, but output fully qualified names when annotating
-clear - clear all prefixes, including the default ones (can be abbreviated as -cl)
-b - output redundant braces (e.g., if(a) { b(); }, default: off)
-d <dir> - directory for output files (will be created when necessary)
-dead - try to decompile dead parts of code (if any) (default: off)
-disass - disassemble method bytecodes (no JAVA source generated)
-f - output fully qualified names for classes/fields/methods (default: off)
-ff - output class fields before methods (default: after methods)
-i - output default initializers for all non-final fields
-l<num> - split strings into pieces of maximum <num> chars (default: off)
-lnc - annotate the output with line numbers (default: off)
-lradix<num> - display long integers using the specified radix (8, 10 or 16)
-nl - split strings on newline character (default: off)
-nocast - don't generate auxiliary casts
-nocode - don't generate the source code for methods
-noconv - don't convert Java identifiers (default: convert)
-noctor - suppress the empty constructors
-nodos - do not check for class files written in DOS mode (CR before NL, default: check)
-nofd - don't disambiguate fields with the same names by adding signatures to their names (default: do)
-noinner - turn off the support of inner classes (default: on)
-nolvt - ignore Local Variable Table information
-nonlb - don't output a newline before opening brace (default: do)
-o - overwrite output files without confirmation (default: off)
-p - send decompiled code to STDOUT (e.g., for piping)
-pi<num> - pack imports into one line after <num> imports (default: 3)
-pv<num> - pack fields with identical types into one line (default: off)
-pa <pfx>- prefix for all packages in generated source files
-pc <pfx>- prefix for classes with numerical names (default: _cls)
-pf <pfx>- prefix for fields with numerical names (default: _fld)
-pe <pfx>- prefix for unused exception names (default: _ex)
-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)
-r - restore package directory structrure
-radix<num> - display integers using the specified radix (8, 10 or 16)
-s <ext> - output file extension (by default '.jad')
-safe - generate additional casts to disambiguate methods/fields (default: off)
-space - output space between keyword (if/for/while/etc) and expression (default: off)
-stat - display the total number of processed classes/methods/fields
-t - use tabs instead of spaces for indentation
-t<num> - use <num> spaces for indentation (default: 4)
-v - display method names being decompiled
-8 - convert UNICODE strings into 8-bit strings
using the current ANSI code page (Win32 only)
-& - redirect STDERR to STDOUT (Win32 only)
