Java 如何从JUnit内部使用伏地魔服务器？

我试图在Maven项目中从JUnit内部使用伏地魔。编译以下代码时，无法成功执行：

@Before
public void setUp() throws Exception
{
    // Start Voldemort
    VoldemortConfig config = VoldemortConfig.loadFromEnvironmentVariable();
    VoldemortServer server = new VoldemortServer(config);
    server.start();
}

而是引发此异常：

知道如何解决这个问题吗？

在stacktrace中记下这一行

在voldemort.utils.JNAUtils.mlockall（本机方法）

这表明无论调用什么代码，都会通过

JNI

使用一些本机库<当JVM在加载请求加载本机库的类时无法加载本机库时，会遇到code>unsatifiedlinkederror

要确保代码可以加载ddl/so文件，请使用以下java系统属性：

-Djava.library.path=/path/to/directory/containing/native/libraries

或者，您可以将相同的目录添加到windows上的

PATH

环境变量，或Linux上的

LD\u LIBRARY\u PATH

变量

查看此页面，了解如何将系统属性传递给负责在maven中运行测试的

maven surefire plugin

。

请不要使用该名称--称之为“你知道谁”
