JNA遇到的坑

记录一下，那些年我们踩过的坑

CLibrary Instance = (CLibrary)Native.loadLibrary("NLPIR",CLibrary.class);

 

有时候打包放在jar的平级目录能读到，其实jna是去这里找的：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'nlpirService' defined in class path resource [nlpir-rmi-server.xml]: Instantiation of bean failed; nested exception is java.lang.UnsatisfiedLinkError: Unable to load library 'NLPIR': Can't obtain InputStream for linux-x86-64/libNLPIR.so

 

用绝对路径：F:\\Desktop\\ICTCLAS2014\\lib\\win32\\NLPIR.dll 

 

乍看比较无厘头，来的目录，而且是相对路径，我们看看jna.jar就明白了

将NLPIR.so扔进去，程序可以跑了。。。

你好，我把so文件放进linux-x86-64下面，报错了
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'jnidispatch': Native library (linux-x86-64/libjnidispatch.so) not found in resource path ([file:/newcapec/jnaTest.jar])
        at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:271)
        at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:398)

能不能帮忙看下
