部署到测试环境时候，总是调用不到，然后输出java地址才发现，如下

/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

前的位置(即你的java jdk的bin目录下，注意有可能在linux上面放那边根本没有生效，所以提前打印查看java.library.path路径查找)。

先输出这个路径，打印的地址，然后把相应的动态库放置其中

String path=System.getProperty("java.library.path");

 

具体的动态库，在Windows下是这三个：

sigar-amd64-winnt.dll
sigar-x86-winnt.dll
sigar-x86-winnt.lib
好了，到此为止，问题解决。

其他系统需要另行选择，库的列表如下：

lib/libsigar-amd64-freebsd-6.so
lib/libsigar-amd64-linux.so
lib/libsigar-amd64-solaris.so
lib/libsigar-ia64-hpux-11.sl
lib/libsigar-ia64-linux.so
lib/libsigar-pa-hpux-11.sl
lib/libsigar-ppc64-aix-5.so
lib/libsigar-ppc64-linux.so
lib/libsigar-ppc-aix-5.so
lib/libsigar-ppc-linux.so
lib/libsigar-s390x-linux.so
lib/libsigar-sparc64-solaris.so
lib/libsigar-sparc-solaris.so
lib/libsigar-universal64-macosx.dylib
lib/libsigar-universal-macosx.dylib
lib/libsigar-x86-freebsd-5.so
lib/libsigar-x86-freebsd-6.so
lib/libsigar-x86-linux.so

lib/libsigar-x86-solaris.so
