Java中的JNI映射结构 [英] JNI mapping structure in java

问题描述

我有一个dll，其中包含例如void abc(meth* myMeth)的方法和结构

I have a dll which has a method for e.g void abc(meth* myMeth) and a structure

struct meth
{
  int a;
  char b[255]; 
} 

上面的代码是用c编写的.我需要通过JNI将此映射到Java，但我遇到了麻烦.如何将对方法abc的引用作为指针从Java方法传递给我，如何设置a和b的值，然后再次传递回Java? 需要紧急帮助....谢谢

The above code code is written in c. I need to map this to Java through JNI, and I am stuck. How can I pass a reference to the method abc as a pointer from a Java method, and how can I set the values of a and b and then pass back to Java again? Need An Urgent Help....Thanks

推荐答案

我不知道这是否适合您，但是请考虑使用一些更高级别的框架来管理低级别的详细信息JNI为您服务.两种选择:

I do not know if this is an option for you, but consider using some higher level framework for managing the low-level details of JNI for you. Two options:

• JNAerator ，另请参见"
• SWIG ，另请参见"

• JNAerator, see also "Structs" chapter in reference documentation.
• SWIG, see also "Structures and unions" chapter in reference documentation.

我个人使用过JNAerator并发现它真的很有帮助.

Personally I have used JNAerator and found it really helpful.
