java.lang.UnsatisfiedLinkError：無法加載庫

Question

DLL INSTANCE = (DLL) Native.loadLibrary(Settings.getSingletonInstance().getProperty("default.ergoPointer.path"), DLL.class);

我將dll路徑存儲在設置文件中。 當我輸出

Settings.getSingletonInstance().getProperty("default.ergoPointer.path"

此處： C:\\Users\\Argenit\\Desktop\\aaa\\dll\\ErgoPointer_64_Bit.dll

錯誤部分：

java.lang.UnsatisfiedLinkError：無法加載庫'C：\\ Users \\ Argenit \\ Desktop \\ aaa \\ dll \\ ErgoPointer_64_Bit.dll'：本機庫（win32-x86-64 / C：\\ Users \\ Argenit \\ Desktop \\ aaa \\ dll \\ ErgoPointer_64_Bit.dll）在資源路徑（[file：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / bin /，file：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / resources /，文件：/ C：/Users/Argenit/Desktop/Pathology_JAVA/Digital_Pathology/lib/fits.jar，文件：/ C：/Users/Argenit/Desktop/Pathology_JAVA/Digital_Pathology/lib/json.jar，文件：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / lib / junit-4.8.2.jar，文件：/ C：/Users/Argenit/Desktop/Pathology_JAVA/Digital_Pathology/lib/kdu_jni.jar，文件：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / lib / log4j-1.2.16.jar，文件：/ C：/Users/Argenit/Desktop/Pathology_JAVA/Digital_Pathology/JNA/jna-4.1.0.jar，文件：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / JNA / jna-platform-4.1.0.jar，文件：/ C：/ Users / Argenit / Desktop / Pathology_J AVA / Digital_Pathology / lib / ini4j-0.5.4.jar，文件：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / JNA /，文件：/ C：/ Users / Argenit / Desktop / Pathology_JAVA / Digital_Pathology / lib /gluegen-rt.jar，文件：/ C：/Users/Argenit/Desktop/Pathology_JAVA/Digital_Pathology/lib/jogl.jar]）

如果我將（dll）添加為項目中的外部類文件夾並編寫： loadLibrary("ErgoPointer_64_Bit") ，則可以在此計算機上運行，​​但是當我使用可運行的jar時，找不到ErgoPointer_64_Bit因此我想給出絕對路徑DLL。 但這對我不起作用。

我也嘗試過：

C：\\用戶\\ Argenit \\桌面\\ AAA \\ DLL \\ ErgoPointer_64_Bit

DLL \\ ErgoPointer_64_Bit

ErgoPointer_64_Bit

DLL \\ ErgoPointer_64_Bit.dll

ErgoPointer_64_Bit.dll

僅使用基本名稱在調用Native.loadLibrary（）之前設置系統屬性java.library.path。

System.setProperty("java.library.path", 
            "C:\\Users\\Argenit\\Desktop\\aaa\\dll;" 
              + System.getProperty("java.library.path"));
DLL INSTANCE = (DLL) Native.loadLibrary("ErgoPointer_64_Bit", DLL.class);

您也可以在命令行上設置java.library.path。 例如。

java "-Djava.library.path=C:\Users\Argenit\Desktop\aaa\dll\" -jar somejar.jar
