类名称：Method
方法名：getGenericParameterTypes

Method.getGenericParameterTypes介绍

[英]Returns an array of Type objects that represent the formal parameter types, in declaration order, of the method represented by this Method object. Returns an array of length 0 if the underlying method takes no parameters.

If a formal parameter type is a parameterized type, the Type object returned for it must accurately reflect the actual type parameters used in the source code.

If a formal parameter type is a type variable or a parameterized type, it is created. Otherwise, it is resolved.
[中]返回类型对象数组，这些对象按声明顺序表示此方法对象表示的方法的形式参数类型。如果基础方法不接受任何参数，则返回长度为0的数组。
如果形式参数类型是参数化类型，则为其返回的类型对象必须准确反映源代码中使用的实际类型参数。
如果形式参数类型是类型变量或参数化类型，则会创建它。否则，问题就解决了。
