no jniopencv_core in java.library.path与no opencv_core245 in java.library.path

eclipse上报这个错，百度了很久，尝试过很多方法，终于解决

1. 配置OpenCV要放在c盘根目录处（不然配置Javacv时会失效）
2. eclipse要配置环境变量到path中 C:\opencv\build\java\x64
3. vs要配置环境变量到path中 C:\opencv\build\x64\vc11\bin

到此还是没能解决报错

1. 导包，不能只导Javacv.jar和javacpp.jar。JavaCV0.6中bin下的包都要导进来，如下图所示。
   

还是错，终于得用杀手锏了（这是我最不愿意尝试的）

1. OpenCV与Javacv版本不匹配的问题
2. 换成OpenCV2.4.6与Javacv0.6版本
3. 完美 解决

我在网上找了许久，官网已经找不到这些老版本的下载了，后来去的CSDN下载的

至于为什么要用这么老的版本，也是有原因的，我在网上看的别人代码学习，其中要用到一些包，比如import static com.googlecode.javacv.cpp.opencv_core.*，这些居然用JavaCV1.2和JavaCV1.5都没有用，换了很多版本，实在没办法，直接按照网上说的，换到JavaCV0.6
