使用javah可以自动从java文件生成jni头文件,

  用法:javah [选项] <类>

  其中 [选项] 包括:

          -help                 输出此帮助消息并退出

          -classpath <路径>     用于装入类的路径

          -bootclasspath <路径> 用于装入引导类的路径

          -d <目录>             输出目录

          -o <文件>             输出文件(只能使用 -d 或 -o 中的一个)

          -jni                  生成 JNI样式的头文件(默认)

          -version              输出版本信息

          -verbose              启用详细输出

          -force                始终写入输出文件

Example:

  工程结构如下:

  

  执行:

    javah -d lib -classpath out/production/VideoSvr -jni cwh.NVR.NVRNative

  关键在于找到正确的classpath,注意-jni 类名要放在最后面写,否则会把-jni后面的东西都当做类名解析的。
