本文介绍了0xC0000005:访问冲突读取位置0x0000000000000000的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用JNI在c ++程序中使用jar文件.

I'm trying to use a jar file in c++ program using JNI.

我这样做了:

// TestJavaToCpp.cpp : Defines the entry point for the console application.
//

#include <jni.h>
#include "stdafx.h"
#include <windows.h>
#include <stdio.h>
#include <iostream>

using namespace std;


int main()
{
    JavaVM *jvm;
    JNIEnv *env;
    JavaVMInitArgs vm_args;
    JavaVMOption options;
    options.optionString = "-Djava.class.path=HelloWorld.jar";
    vm_args.version = JNI_VERSION_1_6;
    vm_args.nOptions = 1;
    vm_args.options = &options;
    vm_args.ignoreUnrecognized = 0;
    int ret = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
    if (ret == 0) {
        jclass cls = env->FindClass("HelloWorld");
        if (cls != 0) {
            jmethodID meth = env->GetStaticMethodID(cls, "Hello", "([Ljava/lang/String;)V");
            jarray args = env->NewObjectArray(0, env->FindClass("java/lang/String"), 0);
            env->CallStaticVoidMethod(cls, meth, args);
        }
    }
    return ret;
}

当HelloWorld.jar与exe文件位于同一文件夹中时.但是，我不断收到错误消息

When HelloWorld.jar is in the same folder with the exe file.However, i keep getting the error

尝试创建JVM时.

现在代码看起来像这样:

EDIT 1:Now code looks like this:

// TestJava.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <jni.h>
#include <Windows.h>
#include <stdio.h>
#include <iostream>

using namespace std;

#define CLEAR(x) memset(&x, 0, sizeof(x))

int main()
{
    JavaVM *jvm(0);
    JNIEnv *env(0);
    JavaVMInitArgs vm_args;
    CLEAR(vm_args);
    JavaVMOption options;
    CLEAR(options);

    options.optionString = "-Djava.class.path=HelloWorld.jar";
    options.extraInfo = 0;
    vm_args.version = JNI_VERSION_1_8;
    vm_args.nOptions = 1;
    vm_args.options = &options;
    vm_args.ignoreUnrecognized = 0;
    int ret = JNI_CreateJavaVM(&jvm, (void **)&env, &vm_args);

    return 0;
}

我只留下了实际创建虚拟机的代码.当它起作用时，我继续，

I left only the code that actually creates the vm. When it'll work, I'll go on,

现在我已经注意到以前出现的错误，但是我没有注意它们:

And now I have noticed to error that showed up before but i didn't pay attention to them:

看大胆的句子.这是引发异常的地方...

Look on the bold sentence. This is where the exception is being thrown...

推荐答案

您需要设置options.extraInfo = 0;

我会尽一切努力做到这一点.防御性编程要求将所有内容初始化.

I would do all of this for good measure. Defensive programming demands that everything is initialized.

#define CLEAR(x) memset(&x, 0, sizeof(x))
JavaVM *jvm(0);
JNIEnv *env(0);
JavaVMInitArgs vm_args;
CLEAR(vm_args);
JavaVMOption options;
CLEAR(options);

注意:

typedef struct JavaVMOption {
    char *optionString;
    void *extraInfo;
} JavaVMOption;

所有这些都不是问题所在.解决方案在注释中-JVM抛出访问冲突异常.它们已被捕获并处理，但是在Visual Studio导致您相信存在问题之前就没有.

None of this turned out to be the problem. The solution is in the comments -- the JVM is throwing access violation exceptions. They are caught and handled, but not before Visual Studio leads you to believe there is a problem.
