java系统库不加载opencv库

标签: java maven opencv dll

我在java项目中使用opencv库。我有一个简单的java项目,编译为' jar',并手动添加opencv库,然后,我知道我必须把这个代码放在什么之后:

  

的System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

这很好用,但是现在,我需要在服务器上运行相同的应用程序,所以我制作了一个简单的maven项目,可以在一场“战争”中编译。并在依赖项中添加了opencv,但是在上面的行中我得到了这个错误。

Caused by: java.lang.UnsatisfiedLinkError: no opencv_java249 in java.library.path

我想这是真的,因为是一个maven依赖。 我怎么解决这个问题?

这是我的pom.xml

更新

我手动添加了库,并且是相同的,war正在编译OK,但是当我执行它时,该行失败并且我得到了相同的错误。

我读到我必须将opencv添加到我的系统变量中,但那不起作用

答案 0 :(得分:3)

您可以解决此问题,添加文件&#34; opencv_java249.dll&#34;到文件夹java / bin /(你已经安装了java)

(是的,这是对我的回答,因为我想帮助那些在同一件事上遇到麻烦的人)
