Text Search无法使用Spring Boot MongoDB
我正在开发Spring Boot + MongoDB + spring data mongo + Text search示例。 通过链接的参考： https ： //spring.io/blog/2014/07/17/text-search-your-documents-with-spring-data-mongodb ，我开发了我的代码，但当我执行时，它给出了空结果集。 请帮助这个场景。 我期待得到两个results OrderId = 10248 and 10249 ，但我得空了。
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 findAllBy(Integer searchValue); }
OrderDetailsServiceImpl.java
@Component public class OrderDetailsServiceImpl implements OrderDetailsService{ @Autowired private OrderDetailsRepository odRepository; @Autowired private MongoOperations mongoOperations; public List 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 =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 = 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以下
@TextIndexed(weight=2) @Field("OrderID") private Integer orderID;
我看到以下错误来了。

注意：boot是我的mongodb名称。
请看另一个编辑：
db['order-details'].getIndexes() /* 0 */ { "0" : { "v" : 1, "key" : { "_id" : 1 }, "name" : "_id_", "ns" : "boot.order-details" } } db['order-details'].createIndex({"OrderID" : "text"}) db['order-details'].getIndexes() { "0" : { "v" : 1, "key" : { "_id" : 1 }, "name" : "_id_", "ns" : "boot.order-details" }, "1" : { "v" : 1, "key" : { "_fts" : "text", "_ftsx" : 1 }, "name" : "OrderID_text", "ns" : "boot.order-details", "weights" : { "OrderID" : 1 }, "default_language" : "english", "language_override" : "language", "textIndexVersion" : 2 } }
first drop db.order-details.dropIndex()命令行db.order-details.dropIndex()
并重构此行TextCriteria criteria = TextCriteria.forDefaultLanguage().matchingPhrase("OrderID").matchingPhrase(String.valueOf(orderId)); 运行申请后
