我正在开发Spring Boot MongoDB弹簧数据mongo文本搜索示例.通过参考链接： https://spring.io/blog/2014/07/17/text-search-your-documents-with-spring-data-mongodb

,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
}

OrderDetailsS​​ervice.java

public interface OrderDetailsService {
    List<OrderDetails> findAllBy(Integer searchValue);
}

OrderDetailsS​​erviceImpl.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？

java – 文本搜索不能与Spring Boot MongoDB一起使用

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.

注意：启动是我的 mongodb 名称.

请参阅另一编辑：

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
    }
}
