Java getMethod抛出方法未找到异常？

Question

I am using the getMethod(String name) function to load a method but it always throws MethodNotFoundException . If I run class.getMethods() the method I am looking for is in that result with the exact name I am using to pass to getMethod() . The method I am trying to load is a static method so I don't know if getMethod() will not work for static methods. Any help?

Answer 1

If the method you're looking for takes any arguments, you need to pass their types to getMethod() as well. A Java method's signature (the thing that uniquely defines and identifies a method) is comprised of the method name and its parameter types.

Answer 2

The name isn't enough. You have to specify exactly which argument types you think the method takes, otherwise the query might be ambiguous (because Java supports overloading).
