在MongoDb中使用正則表達式的Java Spring Boot Json查詢

[英]Java Spring Boot Json Query With Regular Expression In MongoDb

 原文  2017-04-28 10:35:47  3   1    java/ spring-boot/ mongodb-query

問題描述

我需要在春季啟動時執行以下查詢： MongoDb選擇查詢問題Whit正則表達式（Starts Whit和Ends Whit）

我將解釋我的意圖：我想在DDBB中搜索正則表達式（結束並開始搜索）字段Valores和Flag

這是我的存儲庫方法的代碼： 

@Query("{'Valores': { $regex: ?0$, $regex: ^?1} ,'Flag': { $regex: ^?2, $regex: ?3$}}")
List<Curvas> encontrarCurvasPorPattern(String valorInicio,String valorFinal,String flagInicio,String flagFinal);

我嘗試許多這樣的查詢： 

@Query("{'Valores': {$regex: ^[0](;[01])*$} ,'Flag': { $regex: ^[0](;[01])*$}}")

但這不起作用

這里是例外： 

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mongoDbMascotaApplication': Unsatisfied dependency expressed through field 'repository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'curvasRepository': Invocation of init method failed; nested exception is com.mongodb.util.JSONParseException:

此外，我將Java類用於映射： 

@Document(collection = "CollectionName")
public class Curvas {

    @Id
    private String id;
    @Field("Id Curva")
    private int idCurva;
    @Field("Cups")
    private String cups;
    @Field("Magnitud")
    private int magnitud;
    @Field("Fecha")
    private String fecha;
    @Field("Valores")
    private String valores;
    @Field("Flag")
    private String flag;

    public Curvas() {

    }
    // omited getters setters and toString() To abreviate
}

我正在觀看此文檔： http : //docs.spring.io/spring-data/data-document/docs/current/reference/html/#d0e3309

解決了正確的查詢是： 

@Query("{'Valores': { $regex: '?0$', $regex: '^?1'} ,'Flag': { $regex: '^?2', $regex: '?3$'}}")

提前致謝

實際上，您還可以為正則表達式提供選項，如下所示： 

@Query(value = "{'title': {$regex : ?0, $options: 'i'}}")
Foo findByTitleRegex(String regexString);

i選項使查詢不區分大小寫。
