java生成.h文件命令javah使用方式

来源：互联网发布：阿里云蜘蛛池编辑：程序博客网时间：2024/06/06 12:38

javah -classpath . -jni 类路径.JNIClass(提供的接口，编译后)

/***TokenFxxcImpl类中方法声明方式*/public static native Object[] getCreditTokenJni(long meterNo, int sgc, int tariffIndex,            int keyVersion, int keyExpiredTime, long keyNo, int seqNo,            int amount);

示例：F:\android program\Fxxc_T\bin>javah -classpath . -jni com.fxxc.TokenFxxcImpl

F:\android program\Fxxc_T\bin 为编译后的包路径
javah -classpath . -jni 生成.h的java命令
com.fxxc.TokenFxxcImpl 编译后的class带包名的路径
执行完后会在bin目录下生成.h文件com_fxxc_TokenFxxcImpl.h

.h文件内对应方法接口如下

/* DO NOT EDIT THIS FILE - it is machine generated */#include <jni.h>/* Header for class com_fxxc_TokenFxxcImpl */#ifndef _Included_com_fxxc_TokenFxxcImpl#define _Included_com_fxxc_TokenFxxcImpl#ifdef __cplusplusextern "C" {#endif/* * Class:     com_fxxc_TokenFxxcImpl * Method:    getCreditTokenJni * Signature: (JIIIIJII)[Ljava/lang/Object; */JNIEXPORT jobjectArray JNICALL Java_com_fxxc_TokenFxxcImpl_getCreditTokenJni  (JNIEnv *, jclass, jlong, jint, jint, jint, jint, jlong, jint, jint);#ifdef __cplusplus}#endif#endif

最后在C语言中实现H文件中的方法就行
