jad简单用法 最后有简单的例子加注释

 

jad 1.5.8反编译工具使用说明 java反编译工具jad 1.5.8g，可以反编译jdk 1.5，jdk 1.6 反编译工具jad简单用法 以下假设jad.exe在c:\java目录下

 一、基本用法 Usage: jad [option(s)] <filename(s)> 直接输入类文件名，且支持通配符，

如下所示。 C:\java>jad Test.class 或者c:\java\>jad *.class 结果是将Test.class反编译为Test.jad。将Test.jad改为Test.java即得源文件。

二、Option -o 不提示，覆盖源文件(就是第二次反编译时不提示直接覆盖)

三、Option -s c:\java\>jad -sjava Test.class 反编译结果以.java为扩展名。 (注意命令：-sjava)

四、Option -p 将反编译结果输出到屏幕 c:\java\>jad -p Test.class   将反编译结果重定向到文件 c:\java\>jad -p Test.class>Test.java (反编译后直接到Test.java的目录下)

五、Option -d 指定反编译的输出文件目录

六、Option -r  - restore package directory structure

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

 

C:\java>jad -sjava -r  D:/aa/fect/web-inf/classes/com/**/*.class

解释：jad在Ｃ盘java目录下，然后在D:/aa/fect/web-inf/classes/com文件下面有好几层文件，里面存在很多*.class文件

-sjava是把文件反编译后修改后缀名为java，-r重新构造原文件的文件结构。　/**/*.class是在com文件下的所有子文件里的class文件。
