我遇到了与这个问题类似的问题：

在 Mac OS X 上使用 sqlite4java Jar 的 UnsatisfiedLinkError

但是，我在 Mac 上运行，并且我的 lib 文件夹中有相关的库。但是，如果我按原样运行它，我会得到 UnsatisfiedLinkError。如果我运行“java -jar sqlite4java.jar -d”，我会得到以下输出：

sqlite4java 282

我可以看到它正在寻找 sqlite4java-osx-x86_64 库，所以我同时运行了“ln -s libsqlite4java-osx.jnilib libsqlite4java-osx-x86_64.jnilib”和“ln -s libsqlite4java-osx-10.4.jnilib” libsqlite4java-osx-x86_64.jnilib”，这似乎有帮助：

看起来不错，对吧？不。当我尝试运行我的 java 代码时，尝试打开带有 UnsatisfiedLinkError 的数据库时再次失败。

我有什么明显的遗漏吗？这是我的 lib 目录的相关部分的 ls ，作为健全性检查：

这是解决方案：

Exception in thread "main" com.almworks.sqlite4java.SQLiteException:
[-91]cannot load library: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-x86_64
in java.library.path

请尝试运行：

 java -jar sqlite4java.jar -d

使其尝试加载二进制文件的所有变体并验证结果。

结果必须是这样的：

java -jar sqlite4java.jar -d

这些文件按从更具体到不太具体的顺序进行尝试。所以顺序是正确的。

问题是没有更具体的二进制文件 - 所以我们可能需要将libsqlite4java-osx.jnilib重命名为libsqlite4java-osx-amd64.dylib。

升级到 Mountain Lion 后，我的程序出现了同样的错误。当我将库添加到 /Libraries/Java/Extensions 时，他的程序运行良好。我不知道这是否是最好的解决方案，但它确实有效。

不确定到底是什么问题，但您可以尝试在程序中运行 sqlite4java 的诊断代码，看看它是否显示相同的加载顺序：

public Database() {
    com.almworks.sqlite4java.SQLite.main(new String[] {"-d"});
    db = new SQLiteConnection(new File("./test.db"));
    ...

我遇到了同样的问题，但设法通过从 IDE 创建 libs 文件夹然后将 jar 复制到新的 libs 文件夹中来加载 sqlite。然后我从构建路径中删除了旧版本的 jar 并添加到新版本中。希望这可以帮助！
