System.loadLibrary() 从静态块返回异常

本文介绍了System.loadLibrary() 从静态块返回异常的处理方法，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

我创建了一个 Java 应用程序，它从静态初始化块加载一个 Windows DLL.代码片段如下:

I have created a Java app which loads one Windows DLL from the static initialization block. The code snippet is given below:

// MyTestJava class starts
class MyTestJava
{

static
    {
        System.loadLibrary("MyLib");
    }
} // MyTestJava class def ends here

我听说对于从静态块执行的各种库初始化，JVM 应该在 java.library.path 中搜索.所以我为JVM设置库路径如下，并将MyLib.dll放在c:\Libs文件夹下.

I heard that for kinds of library initializations performed from static block, JVM should search in java.library.path. So I set library path for JVM as follows and put MyLib.dll under c:\Libs folder.

options[1].optionString = "-Djava.library.path=C:\\Libs";

不幸的是，我在我的 Java 应用程序中遇到了令人讨厌的 Unsatisfied Link 错误.

Unfortunately I'm getting a pesky Unsatisfied Link Error in my Java app.

推荐答案

不清楚 options[1].optionString = "-Djava.library.path=C:\\Libs"; 是什么意思.您应该将 java.library.path 作为 java arg 传递

Not clear what options[1].optionString = "-Djava.library.path=C:\\Libs"; means. You should pass java.library.path as a java arg

java -Djava.library.path=C:\Libs MainClass
