Hibernate搜索6使用多个关键字搜索多个字段

Question

我想搜索这两个不同的变量：

@Enumerated(EnumType.STRING)
@Column(length = 20)
@Convert(converter = WorksEnumConverter.class)
@GenericField(valueBridge = @ValueBridgeRef(type = WorksValueBridge.class))
private WorksEnum works;

@Convert(converter = AcquisitionTypeConverter.class)
@Enumerated(EnumType.STRING)
@Column(length = 10)
@GenericField(valueBridge = @ValueBridgeRef(type = AcquisitionTypeBridge.class))
private AcquisitionTypeEnum acquisitionType;

如您所见，有两种类型的Enum，我想使用hibernate搜索通过多个关键字进行搜索，我使用了桥接器和转换器，并且我总是得到不能将字符串转换为枚举的错误--这是hibernate搜索实现的代码：

  if (requestSearchCustomer.getKeyword() != null) {
            final String[] keywords = requestSearchCustomer.getKeyword().split(",");
            final SearchPredicate keywordPredicate = getSearchScope().predicate().terms()
                    .fields(RequestDB_.WORKS, RequestDB_.ACQUISITION_TYPE)
                    .matchingAny(keywords).toPredicate();
            predicate.must(keywordPredicate);
        }

如果您想传递字符串，而不是Hibernate搜索所期望的枚举类型，则需要禁用Hibernate搜索的自动转换：

  if (requestSearchCustomer.getKeyword() != null) {
            final String[] keywords = requestSearchCustomer.getKeyword().split(",");
            final SearchPredicate keywordPredicate = getSearchScope().predicate().terms()
                    .fields(RequestDB_.WORKS, RequestDB_.ACQUISITION_TYPE)
                    .matchingAny(Arrays.asList(keywords), ValueConvert.NO).toPredicate();
            predicate.must(keywordPredicate);
        }
