我正在开发Spring Boot + MongoDB + spring data mongo + Text search
示例。通过从链接:https://spring.io/blog/2014/07/17/text-search-your-documents-with-spring-data-mongodb获取引用,我开发了我的代码,但是当我执行它时,它给出了空结果集。请帮助这个场景。我期待得到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<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());
}
}
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。
请参阅其他编辑:
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
}
}
答案 0 :(得分:4)
首先删除索引命令行db.order-details.dropIndex()
并在运行应用程序
后重构此行TextCriteria criteria = TextCriteria.forDefaultLanguage().matchingPhrase("OrderID").matchingPhrase(String.valueOf(orderId));
