当我尝试加载JNI C / C ++ dll库时出现此错误，我注意到它说“崩溃发生在本机代码中的Java虚拟机之外”。不确定那是什么意思？任何帮助将不胜感激！
Java源代码如下：
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：
/* 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
/*
* Class: demojni_Main
* Method: sayHelloWorld
* Signature: ()V
*/
JNIEXPORT void JNICALL Java_demojni_Main_sayHelloWorld
(JNIEnv *, jobject);
#ifdef __cplusplus
}
#endif
#endif
运行Main.java文件时出错：

以下是我在编译，链接和运行时遵循的步骤：
创建/编译头文件：
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.
C / C ++项目的构建/链接器选项：
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.
运行Java文件：
1. In Netbeans Select DemoJNI java project, Main.java->(Right-click)->Run
没有找到使用Cygwin C / C ++编译器的崩溃错误的确切解决方案，但此错误的替代解决方案是使用Microsoft Visual Studios C / C ++编译器。
这是使用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：如果您使用Microsoft Visual Studios C / C ++编译器进行JNI开发，
在win64系统上更新java 8之后，我也反驳了这个问题。如果我们看到日志你会发现“windows-amd64”，我不知道为什么？我按照以下步骤来解决这个问题。
1.从添加 - 删除程序中删除JAVA 8更新
2.删除包含临时目录
3.重新启动PC。
4.立即更新java 8。
5.检查路径C:\Program Files\Java\jdk1.8.0_152\lib它不应该显示文件夹“windows-amd64”。
6.立即检查服务器。
希望这可以帮助。
