Question

我有一个动态的枚举ManufacturerName，我必须添加一个新值（一个新的制造商）。我试过了，但是抛出错误。

 public void createNewManufacturerEnum(final String code, final String name)
{
    try
    {
        final HybrisEnumValue manufacturer =ManufacturerName.valueOf(code);     
        enumerationService.setEnumerationName(manufacturer, name, Locale.GERMAN);
        enumerationService.setEnumerationName(manufacturer, name, Locale.ENGLISH);
...

错误是：

我做错了什么？谢谢！

Answer 1

我尝试了这个，看来它可行。

try
    {
        final HybrisEnumValue manufacturer = ManufacturerName.valueOf(code);
        modelService.save(manufacturer);
        enumerationService.setEnumerationName(manufacturer, name, Locale.GERMAN);
        enumerationService.setEnumerationName(manufacturer, name, Locale.ENGLISH);
    }

Answer 2

为OOTB动态枚举de.hybris.platform.basecommerce.enums.StockLevelStatus提供的示例。

final EnumerationValueModel newStockLevelStatus = modelService.create(StockLevelStatus._TYPECODE);
newStockLevelStatus.setCode("OVERRUN");
newStockLevelStatus.setName("Overrun");
modelService.save(newStockLevelStatus);

Answer 3

您找到了解决方案。这是杂种的例子。请注意，调用setEnumerationName后无需保存。它已经包含对modelService.save的调用。

这是来自EnumerationServiceDemoTest中的SAP hybris的测试中的复制/粘贴

private EnumerationValueModel testEVModel;
//Create the new enum value
testEVModel = modelService.create(OrderStatus.CREATED.getType());
modelService.save(testEVModel);

//find the enumeration for given type and code
final HybrisEnumValue matchingEnumeration = enumerationService.getEnumerationValue([your enumerationCode],
            [your valueCode]);

//setEnumerationName for the given Enum
enumerationService.setEnumerationName(matchingEnumeration, "testName");

//get the name and check if correct
String enumName = enumerationService.getEnumerationName(matchingEnumeration);
assertEquals("testName", enumName);

//setEnumerationName for the given Enum again with german language and check it
enumerationService.setEnumerationName(matchingEnumeration, "neuer_name", Locale.GERMAN);

enumName = enumerationService.getEnumerationName(matchingEnumeration, Locale.GERMAN);
assertEquals("neuer_name", enumName);

Answer 4

尝试在激活“更新正在运行的系统”选项的情况下运行更新。

通过代码在我的动态枚举中添加新值会出错，
