我想在Windows中編寫事件,並且我的應用程序僅支持groovy。Groovy腳本無法找到JNA類
我寫的短代碼來測試,但我得到了以下異常總是:
Java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.platform.win32.Advapi32
at ProcessStateHandler.registerEventSource(test.groovy:32)
at ProcessStateHandler.main(test.groovy:23)
測試代碼是這樣的:
import com.sun.jna.platform.win32.Advapi32
import com.sun.jna.platform.win32.Advapi32Util
import com.sun.jna.platform.win32.Kernel32
import com.sun.jna.platform.win32.Win32Exception
import com.sun.jna.platform.win32.WinNT
import com.sun.jna.platform.win32.WinNT.HANDLE
import com.sun.jna.platform.win32.WinReg
import com.sun.jna.Native
import com.sun.jna.Library
import com.sun.jna.Platform
import com.sun.jna.Pointer
public class ProcessStateHandler {
def APPLICATION_EVENT_LOG_REGISTRY = "SYSTEM\\CurrentControlSet\\Services\\EventLog\\Application"
public static void main(String[] args) {
println "First groovy test"
CLibrary.INSTANCE.printf("Hello, World\n")
ProcessStateHandler processStateHandler = new ProcessStateHandler()
processStateHandler.registerEventSource("", "SourceForTest")
}
private void registerEventSource(String server, String source) {
source = source.trim()
assert Advapi32
// assert Advapi32.INSTANCE
HANDLE eventHandle = Advapi32.INSTANCE.RegisterEventSource(server, source)
}
}
public interface CLibrary extends Library {
CLibrary INSTANCE = (CLibrary) Native.loadLibrary((Platform.isWindows() ? 'msvcrt' : 'c'), CLibrary.class)
void printf(String format, Object... args)
}
在我的猜測,常規不支持變量接口。 Advapi32接口是這樣聲明的。
public interface Advapi32 extends StdCallLibrary {
Advapi32 INSTANCE = (Advapi32) Native.loadLibrary("Advapi32",
Advapi32.class, W32APIOptions.UNICODE_OPTIONS);
/* blah
blah
blah */
}
如何在Advapi32接口中訪問INSTANCE或調用方法?
