use Javassist to add some code statically at the beginning of a method right after the class is compiled. For example,
public String getFoo() {
// add some code here
return "foo";
}
From Eclipse debug, I can not see the added code. Is there a way for Eclipse to show de-compiled code instead of original source?
How to debug it?
Once you've created the CtClass, you can call CtClass.writeFile to save the bytecode of the resulting java class. Then you can use a java decompiler to view the source. The generated source is not perfect ( it would probably not compile ) but it gives you a good idea of what's going on. I use the decompiler built into IntelliJ ( community edition ) but some googling will find you a few other options.
