,我开发了我的代码,但是当我执行它,它给了空的结果集.请在这种情况下帮忙.我期望得到两个结果OrderId = 10248和10249,但我是空的.
我开发的代码:
OrderDetails.java
@Document(collection="order-details") public class OrderDetails { @Id private ObjectId id; //@TextIndexed(weight=2) @Field("OrderID") private Integer orderID; @Field("ProductID") private Integer productID; @Field("UnitPrice") private Double unitPrice; @Field("Quantity") private Integer quantity; @Field("Discount") private Integer discount; // setters and getters }
OrderDetailsService.java
public interface OrderDetailsService { List<OrderDetails> findAllBy(Integer searchValue); }
OrderDetailsServiceImpl.java
@Component public class OrderDetailsServiceImpl implements OrderDetailsService{ @Autowired private OrderDetailsRepository odRepository; @Autowired private MongoOperations mongoOperations; public List<OrderDetails> findAllBy(Integer searchValue) { //TextCriteria criteria = TextCriteria.forDefaultLanguage().matchingAny(searchValue); TextCriteria criteria = TextCriteria.forDefaultLanguage().matchingPhrase("OrderID") .matchingPhrase(String.valueOf(searchValue)); Query query = TextQuery.queryText(criteria).sortByScore(); List<OrderDetails> orderDetails =mongoOperations.find(query, OrderDetails.class); return orderDetails; } }
MainController.java
@Controller public class MainController implements CommandLineRunner { private Logger LOGGER = Logger.getLogger(MainController.class); @Autowired private OrderDetailsService odService; @Override public void run(String... args) throws Exception { LOGGER.info("~~ STARTED ~~"); // Find OrderID List<OrderDetails> orderDetails = odService.findAllBy(102); LOGGER.info("Order Details Size :"+orderDetails.size()); } }
MondoDB看起来像?
如果我在模型类中使用下面的代码
@TextIndexed(weight=2) @Field("OrderID") private Integer orderID;
我看到以下错误来了.
