使用 Java SDK 的 VMware Vsphere 自定义属性

Question

我正在尝试使用 VMware JAVA SDK 向 VM ware vSphere 添加新的自定义属性，但它抛出 "InvalidType" 异常。

代码

ServiceInstance si = null;
    try {
        si = Initialisation(url, user, password);
    } catch (RemoteException e) {

        e.printStackTrace();
    } catch (MalformedURLException e) {

        e.printStackTrace();
    }

    ServerConnection serverConnection = si.getServerConnection();
    ManagedObjectReference  mor = si.getMOR();

    CustomFieldsManager cfm = new CustomFieldsManager(serverConnection, mor);
    try {
        cfm.addCustomFieldDef("type", null, null, null);
    } catch (DuplicateName e) {
        e.printStackTrace();
    } catch (InvalidPrivilege e) {
        e.printStackTrace();
    } catch (RuntimeFault e) {
        e.printStackTrace();
    } catch (RemoteException e) {
        e.printStackTrace();
    }

与 vSphere 的连接工作正常，因为我能够检索或更改现有的自定义属性，但无法创建新属性。

上面的代码有什么问题？或者有没有其他方法可以使用 vmware Java SDK 添加新的自定义属性。

下面是我定义的标签class。自定义属性的键对所有 VMware 资源都是全局的，并且每个资源的值仅发生变化。因此，如果您要向 VM 或主机添加新的自定义属性键，则需要全局添加键，然后为该非常特定的资源更改该键的值。

下面是有效的 java 示例。

public class Tag{
       String key;
       String value;
    }

public void addTags(ServiceInstance serviceInstance, VirtualMachine virtualMachine, List<Tag> tags) throws CloudServiceException, CloudParameterException{
        if(EmptyUtil.isNotEmpty(tags)){
            CustomFieldsManager customFieldsManager = serviceInstance.getCustomFieldsManager();
            CloudValidate.resourceNotNull(customFieldsManager, "Custom Fields cannot be set for VM as CustomFieldsManager instance could not be obtained.");
            CustomFieldDef[] customFieldDefs = customFieldsManager.getField();
            Set<String> existingTags = getExistingTags(customFieldDefs);
            for(Tag tag : tags){
                if(!existingTags.contains(tag.getKey())){
                    updateTagsKey(customFieldsManager, tag.getKey());
                }
                updateTagsValue(virtualMachine, tag);
            }
        }
    }

    private void updateTagsKey(CustomFieldsManager customFieldsManager, String key){
        try {
            customFieldsManager.addCustomFieldDef(key, Constants.VMWARE_CUSTOMATTRIBUTE_TYPE_VM, null, null);
        }catch (DuplicateName dname){
            logger.warn("Custom attribute : {} already exists.", key);
        }catch(Exception exception) {
            logger.warn("Failed to add custom field due to : {}.", exception.getMessage());
        }
    }

    private void updateTagsValue(VirtualMachine virtualMachine, Tag tag){
        try{
            logger.info("Adding {} for Virtua Machine {}", tag.toString(), virtualMachine.getName());
            virtualMachine.setCustomValue(tag.getKey(), tag.getValue());
        }catch(Exception exception) {
            logger.warn("Failed to set custom attribute on VM due to  : {}.", exception.getMessage());
        }
    }

    private Set<String> getExistingTags(CustomFieldDef[] customFieldDefs){
        Set<String> existingTags = new HashSet<>();
        if(EmptyUtil.isNotEmpty(customFieldDefs)){
            for(CustomFieldDef customFieldDef : customFieldDefs){
                existingTags.add(customFieldDef.getName());
            }
            logger.debug("Existing Custom Fields from Custom Fields Manager : {}", Arrays.toString(existingTags.toArray()));
        }
        return existingTags;
    }
