调用invokeMethod时出错

Question

可能是什么问题？

invokeMethod(op,        
  "write",        
  inArgs,         //input argument array -> Passing a string
   null);

这个异常的原因可能是什么？

Answer 1

当你谈论 Java Reflection 时，这是无关紧要的。您无法将 4000 字节的参数传递给方法。您可以传递的最大值为 8 个字节。因为这是 Java 中最大数据类型的大小：long、double。即使数组也是 4 个字节，因为它是一个对象，由内存指针表示。

所以，我认为你必须在其他地方寻找你的问题......
