I have this servlet -
@WebServlet("/CreateNewPersonServlet")
public class CreateNewPersonServlet extends HttpServlet {
private void saveInDB() {
// here use the invoke ...
String methodName = "saveManager";
Method method = CreateNewPersonServlet.class.getMethod(
methodName, new Class[] {});
method.invoke(this);
}
private void saveManager() {
}
}
When the running reach to the line -
Method method = CreateNewPersonServlet.class.getMethod(
methodName, new Class[] {});
it throws the exception -
java.lang.NoSuchMethodException: control.CreateNewPersonServlet.saveManager()
at java.lang.Class.getMethod(Unknown Source)
How I should write the invoke correctly ?
The method is private, you should use .getDeclaredMethod(..)
, and then use setAccessible(true)
.getMethod(..)
returns only public methods. But you may as well make the method public.
