在Mac OS X NetBeans上使用sqlite4java Jar的UnsatisfiedLinkError
我遇到了与此问题类似的问题：
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，我会收到UnsatisfiedLinkError。 如果我运行“java -jar sqlite4java.jar -d”，我会得到以下输出：

看起来很好，对吗？ 当我尝试运行我的java代码时，尝试使用UnsatisfiedLinkError打开数据库时，它再次失败。
有什么明显的东西我不见了吗？ 这是我的lib目录中相关部分的ls，只是作为一个完整性检查：

以及我的数据库连接代码的副本：

感谢你能解决我的问题……

为了回应@sereda，这里是输出“com.almworks.sqlite4java.SQLite.main（new String [] {” – d“}）;” 进入数据库连接代码：

这是以下解决方案：
Exception in thread "main" com.almworks.sqlite4java.SQLiteException: [-91]cannot load library: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-x86_64 in java.library.path
请尝试运行此：
java -jar sqlite4java.jar -d
使其尝试加载二进制文件的所有变体并validation结果。
结果必须是这样的：
java -jar sqlite4java.jar -d sqlite4java 282 121212:134119.239 FINE [sqlite] Internal: loading library 121212:134119.239 FINE [sqlite] Internal:java.library.path=/Users/XXXXX/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:. 121212:134119.240 FINE [sqlite] Internal: sqlite4java.library.path=null 121212:134119.240 FINE [sqlite] Internal: cwd=XXXXX 121212:134119.240 FINE [sqlite] Internal: default path=XXXXX 121212:134119.240 FINE [sqlite] Internal: forced path=null 121212:134119.240 FINE [sqlite] Internal: os.name=mac os x; os=osx 121212:134119.240 FINE [sqlite] Internal: os.arch=x86_64 121212:134119.240 FINE [sqlite] Internal: trying to load sqlite4java-osx-x86_64 121212:134119.243 FINE [sqlite] Internal: cannot load sqlite4java-osx-x86_64: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-x86_64 in java.library.path 121212:134119.243 FINE [sqlite] Internal: trying to load sqlite4java-osx-amd64 121212:134119.244 FINE [sqlite] Internal: cannot load sqlite4java-osx-amd64: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-amd64 in java.library.path 121212:134119.244 FINE [sqlite] Internal: trying to load sqlite4java-osx-10.4 121212:134119.249 INFO [sqlite] Internal: loaded sqlite4java-osx-10.4 from system path 121212:134119.252 INFO [sqlite] Internal: loaded sqlite 3.7.10, wrapper 0.2 SQLite 3.7.10 Compile-time options: ENABLE_COLUMN_METADATA ENABLE_FTS3 ENABLE_FTS3_PARENTHESIS ENABLE_LOCKING_STYLE=0 ENABLE_MEMORY_MANAGEMENT ENABLE_RTREE OMIT_DEPRECATED TEMP_STORE=1 THREADSAFE=1
这些文件按照更具体的特定顺序进行尝试。 所以订单是正确的。
问题是没有更具体的二进制文件 – 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，程序运行正常。 我不知道这是否是最好的解决方案，但它确实有效。
不确定究竟是什么问题，但您可以尝试从程序中运行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")); ...
我有同样的问题，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！
