当前的JNA版本在构建时被写入到名为Version的接口中的常量VERSION中。该接口是包私有的，但由Native类实现，因此可以从Native中公开访问该常量。（代码检查工具可能会提出警告。）所以你可以简单地这样做：
import com.sun.jna.Native;
public class Test {
public static void main(String[] args) {
System.out.println("JNA版本：" + Native.VERSION);
}
}
输出：
JNA版本：5.6.0
你还可以获取本机部分的版本，本机部分的版本遵循与整个项目版本不同的编号方案（对于不更改已编译的本机部分的新映射进行递增），但在某些情况下可能相关：
System.out.println("JNA本机版本：" + Native.VERSION_NATIVE);
Native类还公开了一个boolean类型的isCompatibleVersion()方法，你可以使用它来检查JNA是否至少是指定版本或更高版本。
英文:
The current JNA version is written at build time to a constant VERSION in the appropriately-named Version interface. That interface is package private, but is implemented by the Native class, making the constant publicly available from Native. (Linters may complain.) So you can simply do:
import com.sun.jna.Native;
public class Test {
public static void main(String[] args) {
System.out.println("JNA Version: " + Native.VERSION);
}
}
Output:
JNA Version: 5.6.0
You can also get the version of the native bits, which follow a different numbering scheme than the overall project version (which is incremented with new mappings that don't change the compiled native portions), but may be relevant in some contexts:
System.out.println("JNA Native Version: " + Native.VERSION_NATIVE);
The Native class also exposes a boolean isCompatibleVersion() method which you can use to check whether JNA is at least the specified version or higher.
