JNI_CreateJavaVM退出代码-1？

我在JNI_CreateJavaVM方法创建JVM时遇到问题，应用程序只是“程序”[4616] VnptTokenCplusplus.exe：Native已退出代码1（0x1）。“，有人能为我解释一下吗？

#include  #pragma comment(lib,"jvm"); JNIEnv* Vnpt_JavaCreateVM(); void Vnpt_JavaInvokeClass(JNIEnv* env); int main(){ JNIEnv* env = 0; env = Vnpt_JavaCreateVM(); Vnpt_JavaInvokeClass(env); getchar(); } JNIEnv* Vnpt_JavaCreateVM() { jint res; JavaVM* jvm; JNIEnv* env; JavaVMInitArgs args; JavaVMOption options[1]; args.version = JNI_VERSION_1_2; // JNI_VERSION_1_2 is interchangeable for this example args.nOptions = 1; options[0].optionString = "-Djava.class.path=."; args.options = options; args.ignoreUnrecognized = JNI_FALSE; res = JNI_CreateJavaVM(&jvm, (void **)&env, &args); if(res FindClass( "com/vnpt/TestJDialog"); mainMethod = env->GetMethodID(mainClass, "tokenNotify", "()V"); env->CallVoidMethod(mainClass, mainMethod); } 

并输出：

Answer 1

我遇到了同样的问题并做了两件事来解决它：

1-将jvm.dll所在的位置（应位于程序文件\ java \ jsdk_ * \ bin \ server中）添加到Windows机器上的PATH环境变量中

2-尝试更改“-Djava.class.path =”。 指向实际目录或.jar文件（为我工作）
