Javah生成JNI头文件方法

（1）javac编译技巧 自动生成包目录

javac -d . *.java

自然生成带包的文件了

（2）javah使用生成c头文件

java

public class HelloJNI {
	public  native void hello(int i ); 
}

命令中执行　

-bash-4.1# pwd
/home/jni
-bash-4.1# ls
HelloJNI.java
-bash-4.1# more HelloJNI.java
package com.venustech.jni;

public class HelloJNI {
public native void hello(int i );
}
-bash-4.1# javac -d . HelloJNI.java
-bash-4.1# ls
com HelloJNI.java
-bash-4.1# javah -classpath . com.venustech.jni.HelloJNI
-bash-4.1# ls
com com_venustech_jni_HelloJNI.h HelloJNI.java
