回調文件系統和“ java.library.path中沒有jnicbfs”錯誤

Question

enter code here我使用standart安裝包中的示例創建了一個簡單的代碼，用於將虛擬磁盤安裝到系統中。 Java示例。 因此，在我創建了一些單元測試之后，第一個是將磁盤安裝到系統中並檢查是否已安裝了磁盤，第二個試圖安裝磁盤並嘗試創建簡單文件來檢查創建/打開等事件。文件，因此，如果我僅使用一個測試，則一切工作正常，如果兩個都收到錯誤no jnicbfs in java.library.path可以有人幫助我解決此問題嗎？ PS-許可證正在試用-下面的簡單代碼

  @Override
    public boolean createVirtualDisk(String diskLetter) {

        CallbackFileSystem callbackFileSystem;
        boolean isCreated = true;

        try {

            // create CbFS instance
            callbackFileSystem = new CallbackFileSystem(new CloudFileSystemEventHandler());

            //initialize system properties
            initCallBackFileSystemProperties(diskLetter, callbackFileSystem);

            // mount point
            callbackFileSystem.mountMedia(0);

        } catch (ECBFSError e) {
            LOGGER.error(e.getMessage(), e);
            isCreated = false;
        }

        return isCreated;
    }

    private void initCallBackFileSystemProperties(String volumeKey, CallbackFileSystem callbackFileSystem) throws ECBFSError {
        callbackFileSystem.setRegistrationKey(cloudFileSystemProperties.getLicenseKey());
        callbackFileSystem.setSerializeCallbacks(cloudFileSystemProperties.isSerializeCallbacks());
        callbackFileSystem.setThreadPoolSize(cloudFileSystemProperties.getThreadPoolSize());
        callbackFileSystem.setProcessRestrictionsEnabled(cloudFileSystemProperties.isProcessRestrictionsEnabled());
        callbackFileSystem.createStorage();
        callbackFileSystem.disableMetaDataCache(cloudFileSystemProperties.isMetaDataCacheDisable());
        callbackFileSystem.addMountingPoint(volumeKey);
    }

測試1：

        CbFSProperties cbFSProperties = createCloudFileSystemProperties();
        // create CloudFileSystemImpl context
        CloudFileSystemContext cloudFileSystemContext = new CloudFileSystemContext(cbFSProperties);


        // create volume
        CloudFileSystem cloudFileSystem = new CloudFileSystemImpl(cloudFileSystemContext);
//
        boolean isCreated = cloudFileSystem.createVirtualDisk("R:");

        // check if volume was created correctly
        CallbackFileSystem callbackFileSystem = new CallbackFileSystem();
        callbackFileSystem.setRegistrationKey(cbFSProperties.getLicenseKey());

        // check created or not
        Assert.assertEquals(true, isCreated);

        // the same assertion
        Assert.assertEquals("R", callbackFileSystem.getMountingPoint(0));

2：

 CbFSProperties cbFSProperties = createCloudFileSystemProperties();
// create CloudFileSystemImpl context
CloudFileSystemContext cloudFileSystemContext = new CloudFileSystemContext(cbFSProperties);

// create volume
CloudFileSystem cloudFileSystem = new CloudFileSystemImpl(cloudFileSystemContext);

boolean isCreated = cloudFileSystem.createVirtualDisk("S:");

if (isCreated)
    createFileOnDisk("S:\\test.txt");
else
    Assert.assertTrue("The disk was not created.", false);

具有java.library.path的Maven文件

Answer 1

我使用了系統屬性，但是未設置java.library.path ，在此之后，我嘗試使用特殊屬性，並且所有屬性都可以正常工作，如博客所述

工作的Maven插件是

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
         <forkMode>once</forkMode>
         <workingDirectory>target</workingDirectory>
        <argLine>-Djava.library.path=${basedir}/lib</argLine>
    </configuration>
</plugin>
