需要幫助獲得librxtxSerial.jnilib進入可運行jar文件

Question

public static void main(String[] args) { 

portList = CommPortIdentifier.getPortIdentifiers(); 

    while (portList.hasMoreElements()) { 
     portId = (CommPortIdentifier) portList.nextElement(); 
     if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {

我需要創建我的項目的可運行jar文件，其中包括3類，外部RXTX庫和librxtxSerial.jnilib在project.But創建可運行jar文件時，該librxtxSerial未包含在jar文件中的.jnilib文件。我認爲這是運行jar文件時沒有得到輸出的原因。

Answer 1

JNI庫由操作系統加載。因此，它們不能直接從jar文件加載。它們從文件系統加載（有關詳細信息，請參見java.load.path）。

您可以嘗試將安裝程序集成到您的java代碼中，該代碼會在加載本機代碼之前將lib文件中的lib複製到文件系統中。
