Jvm JNA调用适用于32位JRE，但不适用于64位JRE

我试图从我创建的JNA接口调用system32的CreateProcessW。问题是，当我从32位JRE运行软件时，它工作正常，但当我转到64位JRE时，它会使JVM崩溃

Kernel32 kernel = (Kernel32) Native.loadLibrary("kernel32",
        Kernel32.class, new HashMap<String, Object>() {
            private static final long serialVersionUID = 1L;

            {
                put(Library.OPTION_FUNCTION_MAPPER,
                        W32APIFunctionMapper.UNICODE);
                put(Library.OPTION_TYPE_MAPPER,
                        W32APITypeMapper.UNICODE);
            }
        });

ProcessInformation processInformation = new ProcessInformation();
byte[] startupInfo = new byte[67];

int num2 = BitConverter.toInt32(bytes, 60);
int num = BitConverter.toInt16(bytes, num2 + 6);
IntByReference ptr4 = new IntByReference(BitConverter.toInt32(bytes, num2 + 0x54));
kernel.CreateProcessW(surrogateProcess, null, 0, 0, false, 4, 0,
            null, startupInfo, processInformation);

My ProcessInformation JNA结构：

public final class ProcessInformation extends Structure implements ByReference {

    public IntByReference hProcess;
    public IntByReference hThread;
    public int dwProcessId;
    public int dwThreadId;

    @Override
    protected List<String> getFieldOrder() {
        return Arrays
                .asList("hProcess", "hThread", "dwProcessId", "dwThreadId");
    }

}

你的地图是假的。您是从哪里想到可以使用Java

int

来表示指针值的？哦，没关系，win32 API一定教会了你这一点

您必须使用

指针

或

指针类型

或等效物来表示指针，或者如果您确实坚持使用整数值，至少在64位平台上使用

long

（64位）

顺便说一句，JNA包括一个

platform.jar

，其中包括内核32映射，包括

CreateProcess

public final class ProcessInformation extends Structure implements ByReference {

    public IntByReference hProcess;
    public IntByReference hThread;
    public int dwProcessId;
    public int dwThreadId;

    @Override
    protected List<String> getFieldOrder() {
        return Arrays
                .asList("hProcess", "hThread", "dwProcessId", "dwThreadId");
    }

}
