Question

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

我将dll路径存储在设置文件中。当我拿出

的输出

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

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

错误部分：

java.lang.UnsatisfiedLinkError：无法加载库＆＃39; C：\ Users \ Argenit \ Desktop \ aaa \ dll \ ErgoPointer_64_Bit.dll＆＃39;：Native 图书馆（Win 32的x86-64的/ C：\用户\ Argenit \桌面\ AAA \ DLL \ ErgoPointer_64_Bit.dll）在资源路径中找不到（[文件：/ C：/用户/ Argenit /桌面/ Pathology_JAVA / Digital_Pathology / bin中/，文件：/ C：/用户/ Argenit /桌面/ Pathology_JAVA / Digital_Pathology /资源/，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_JAVA/Digital_Pathology/lib/ini4j-0.5.4.jar，文件：/ C：/用户/ Argenit /桌面/ 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]）

如果我在项目中添加（dll）作为外部类文件夹并写入：loadLibrary("ErgoPointer_64_Bit")，它可以在这台机器上工作，但是当我拿到可运行的jar时，它就无法运行。找到ErgoPointer_64_Bit所以我想给出dll的绝对路径。但它没有＆＃39;为我工作。

我也尝试过：

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

DLL \ ErgoPointer_64_Bit

ErgoPointer_64_Bit

DLL \ ErgoPointer_64_Bit.dll

ErgoPointer_64_Bit.dll

在使用基本名称调用Native.loadLibrary（）之前设置系统属性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);

您还可以在命令行上设置java.library.path。例如

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

java.lang.UnsatisfiedLinkError：无法加载库
