获取类运行是的结构

Class<?> aClass = Class.forName("com.atguigu.mybatis.bean");

        //获取本类及其父类的public方法
        Method[] methods = aClass.getMethods();
        for (Method method : methods) {
            System.out.println(method);
        }

 Class<?> aClass = Class.forName("com.atguigu.mybatis.bean");

//获取本类的全部方法
 Field[] declaredFields = aClass.getDeclaredFields();
        for (Field declaredField : declaredFields) {
            System.out.println(declaredField);
        }
