本文介绍了Java运行时环境-.EXCEPTION_ACCESS_VIOLATION检测到致命错误的处理方法，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
当我尝试加载JNI C / C ++ dll库时，出现此错误，并且我注意到它说崩溃发生在Java虚拟机外部，以本机代码显示。不确定那是什么意思？
Java源代码如下：
软件包demojni;
公共类Main {
静态{
System.load（ C：\\Users\\Nicholas1\\Documents\\NetBeansProjects\\DemoJNI_Lib \\dist\\DemoJNI_Lib.dll）; //在运行时加载本机库
// hello.dll（Windows）或libhello.so（Unixes）
}
//声明一个接收本机方法sayHello（）什么也不会返回void
//测试驱动程序
public static void main（String [] args）{
new Main（）。sayHelloWorld（）; //调用本地方法
}
private native void sayHelloWorld（）;
}
C源代码如下：
#include DemoJNI_Lib.h
#include< stdio.h>
JNIEXPORT void JNICALL Java_demojni_Main_sayHelloWorld
（JNIEnv * env，jobject obj）{
printf（ Hello World \n）;
}
JNI C-header-源代码如下：
/ *不要编辑此文件-它是机器生成的* /
#include< jni.h>
/ *类标题demojni_Main * /
#ifndef _Included_demojni_Main
#define _Included_demojni_Main
#ifdef __cplusplus
extern C {
#endif
/ *
*类：demojni_Main
*方法：sayHelloWorld
*签名：（）V
* /
JNIEXPORT void JNICALL Java_demojni_Main_sayHelloWorld
（JNIEnv *，jobject）;
#ifdef __cplusplus
}
#endif
#endif
运行Main.java文件时出错：

经过的时间：27秒（0d 0h 0m 27s）
以下是我进行编译，链接和运行的步骤：
创建/编译头文件：
1。在 C：\Users\Nicholas1\Documents\NetBeansProjects中打开cmd提示符。
2.运行 javah –o DemoJNI_Lib / DemoJNI_Lib.h –classpath DemoJNI / src demojni.Main，其中；
- DemoJNI_Lib是您的C ++动态库项目。
-C类文件的Java / C标头中的DemoJNI_Lib.h声明。
-DemoJNI是带有src文件夹的Java项目的名称。
-demojni是您的Java项目包名称
-Main是您的主要Java文件。
C / C ++项目的构建/链接器选项：
1。右键单击DemoJNI_Lib项目，然后选择属性。转到Build / C编译器，然后在常规/包含目录下查看并单击目录按钮（…），然后选择添加按钮。现在，从 C：\Program Files\Java\jdk1.8.0_111\include中选择include文件夹，然后选择添加按钮，并从 C：\Program Files\Java\jdk1中选择win32文件夹。 .8.0_111\include / win32，最后选择确定按钮。
2.右键单击DemoJNI_Lib项目，然后选择属性。转到Build / C-Compiler，找到命令行 /其他选项，然后键入 -shared –m32
3.右键单击DemoJNI_Lib项目，然后选择属性 Build / Linker，找到常规 /输出，然后键入dist / DemoJNI_Lib.dll
4.可选：添加typedef long long __int64;或#define __int64 long到DemoJNI_Lib.h文件的顶部。应该高于#include< jni.h>。
5.生成.dll库文件：在Netbeans中找到带有c文件和头文件的C / C ++项目，然后找到Project->（右键单击）-> Clean and Build。
正在运行的Java文件：
1。在Netbeans Select DemoJNI Java项目中，Main.java->（右键单击）->运行
解决方案
尚未找到Cygwin C / C ++编译器对崩溃错误的确切解决方案，但是该错误的替代解决方案是使用Microsoft Visual Studios C / C ++编译器。 / p>
以下是使用Microsoft Visual Studios C / C ++编译器的JNI解决方案的链接： https://www.youtube.com/watch?v=tDhOPYi-rYE&spfreload=1
注意：如果使用Microsoft Visual Studio C / C ++编译器进行JNI开发，则
-
对于32位dll使用 vsvars32.bat，位于 C：\程序文件（x86）\ Microsoft Visual Studio 14.0\Common7\Tools。
-
对于我的安装程序，我需要一个64位dll文件，因此我使用在 C：\Program Files（x86）\Microsoft Visual Studio 14.0\VC\bin\am中找到的 vcvars64.bat d64
This error appears when I try to load a JNI C/C++ dll library, and I noticed it says "The crash happened outside the Java Virtual Machine in native code." Not sure what that means? Any help will be greatly appreciated!
Java-Source code follows:
package demojni;
public class Main {
static {
System.load("C:\\Users\\Nicholas1\\Documents\\NetBeansProjects\\DemoJNI_Lib\\dist\\DemoJNI_Lib.dll"); // Load native library at runtime
// hello.dll (Windows) or libhello.so (Unixes)
}
// Declare a native method sayHello() that receives nothing and returns void
// Test Driver
public static void main(String[] args) {
new Main().sayHelloWorld(); // invoke the native method
}
private native void sayHelloWorld();
}
C-Source code follows:
#include "DemoJNI_Lib.h"
#include <stdio.h>
JNIEXPORT void JNICALL Java_demojni_Main_sayHelloWorld
(JNIEnv * env, jobject obj){
printf("Hello World \n");
}
JNI C-header-Source code follows:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class demojni_Main */
#ifndef _Included_demojni_Main
#define _Included_demojni_Main
#ifdef __cplusplus
extern "C" {
#endif
/*

*/
JNIEXPORT void JNICALL Java_demojni_Main_sayHelloWorld

The Following are my Steps I followed for Compilation, Linking and Running:
Creating/Compilation Header file:
1. Open cmd prompt in "C:\Users\Nicholas1\Documents\NetBeansProjects"
2. Run "javah –o DemoJNI_Lib/DemoJNI_Lib.h –classpath DemoJNI/src demojni.Main", where;
- "DemoJNI_Lib" is your C++ dynamic library project.
- DemoJNI_Lib.h declaration for your Java/C header for the C-class file.
- DemoJNI is the name of your java project with src folder.
- demojni is your java project package name
- Main is your main java file.
Build/Linker options for C/C++ Project:
1. Right-click on DemoJNI_Lib project and select properties. Go to Build/C Compiler then look under General/Include Directories and click on directories button(…), then select Add button. Now select the include folder from "C:\Program Files\Java\jdk1.8.0_111\include", then select Add button and select the win32 folder from "C:\Program Files\Java\jdk1.8.0_111\include/win32", finally choose OK-button.
2. Right-click on DemoJNI_Lib project and select properties. Go to Build/C-Compiler find "Command Line"/"Additional Options", then type "-shared –m32"
3. Right-click on DemoJNI_Lib project and select properties "Build"/"Linker", find "General"/"Output", then type dist/DemoJNI_Lib.dll
4. Optional:Add typedef long long __int64; or #define __int64 long long to top of DemoJNI_Lib.h file. Should be above #include <jni.h>.
5. Build .dll library file: in Netbeans find C/C++ project with c-file and header-file, then Project->(right click)->Clean and Build.
Running Java file:
1. In Netbeans Select DemoJNI java project, Main.java->(Right-click)->Run
解决方案
Have not figured out the exact solution to the crash error with the Cygwin C/C++ Compiler, But the alternative solution to this error is to use the Microsoft Visual Studios C/C++ Compiler.
Here's a link to a JNI solution that uses the Microsoft Visual Studios C/C++ Compiler: https://www.youtube.com/watch?v=tDhOPYi-rYE&spfreload=1
Note: If you use Microsoft Visual Studios C/C++ Compiler for JNI development,
For a 32-bit dll use "vsvars32.bat" found at "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools".
For my setup I needed a 64-bit dll file so I used "vcvars64.bat" found at "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64"
