[jboss-user] [Javassist Users] - Javassist can't seem to instrument static method
I stumbled upon a Javassist problem, when it fails to add code with insertBefore().
If someone can help, I would really appreciate this.
| package test;
| public class TheAddress extends TheModel {
| static{
| foo("The address!!!");
| }
| }
|
| package test;
| public class TheModel {
| public static void foo(String param){
| System.out.println("Inside foo, param: " + param);
| }
| }
| package test;
| import javassist.*;
| public class JavassistTest {
|
| public static void main(String[] args) throws Exception {
|
| ClassPool pool = ClassPool.getDefault();
| CtClass clazz = pool.get("test.TheAddress");
| CtMethod foo = getMethod("foo", clazz);
|
| foo.insertBefore("{ System.out.println(\"inserted before
foo!\");}");
|
| clazz.writeFile();
| clazz.toClass().newInstance();
| }
|
| static CtMethod getMethod(String name, CtClass target){
| for (CtMethod method : target.getMethods()) {
| if (name.equals(method.getName())) return method;
| }
| return null;
| }
| }
cheers!
