java - JNI_CreateJavaVM 退出代码 -1？

Question

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，代码为 1 (0x1)。”有人能为我解释一下吗？

#include <jni.h>
#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 < 0)
    {
    }
    return env;
}
void Vnpt_JavaInvokeClass(JNIEnv* env) {
    jclass mainClass;
    jmethodID mainMethod;

    mainClass = env->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(应该在program files\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(对我有用)
