Я использую myBatis, и мне нужно вызвать сгенерированный andFieldEqualTo метод с использованием Java Reflection.
Class<?> cls = Class.forName("com.example.model.MyBatisExample");
Object obj = cls.newInstance();
Method method = cls.getDeclaredMethod("createCriteria");
Method method2 = method.invoke(obj).getClass().getDeclaredMethod("andFieldEqualTo", String.class);
Когда я запускаю приведенный выше код, я получаю эту ошибку:
java.lang.NoSuchMethodException: com.oneconnectft.sg.smartdocu.model.UserGroupExample $ Criteria.andFieldEqualTo (java.lang.String)
Для справки это класс MyBatisExample
package com.example.model;
import java.util.ArrayList;
import java.util.List;
public class MyBatisExample {
