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!
