在 MongoDb 中使用正则表达式进行 Java Spring Boot Json 查询答案

【问题标题】：Java Spring Boot Json Query With Regular Expression In MongoDb在 MongoDb 中使用正则表达式进行 Java Spring Boot Json 查询
【发布时间】：2017-09-26 10:49:28
【问题描述】：

我需要在 spring boot 中做这个查询：MongoDb Select Query Issue Whit Regular Expression (Starts whit and Ends Whit)

我将解释我的意图：我想在 DDBB 中搜索一个正则表达式（以正则表达式结束并开始）字段 Valores 和 Flag

这是我的仓库方法的代码：

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

我尝试了很多这样的查询：

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

但它不起作用

这里是例外：

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，我将我的 java 类用于映射：

@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
}

我在看这个文档：http://docs.spring.io/spring-data/data-document/docs/current/reference/html/#d0e3309

解决了正确的查询是：

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

提前致谢

【问题讨论】：

尝试转义“$”...可能是\$ 或\\$
对不起，它不起作用
JSON 查询格式不正确。我们可以看到根本原因JSONParseException。是否可以将 $ 与参数一起包含在内，以便最终的 json 类似于 { 'Valores': { $regex: "_param_0$", $regex: "^_param_1" }, 'Flag': { $regex: "^_param_2", $regex: "_param_3$" } }
非常感谢！！！它有效，我只需要将您的代码的“更改为”，它在我的问题中有效，我将编辑问题，正确的查询将您的评论作为关闭此问题的答案，再次感谢！

【解决方案1】：

您实际上还可以为您的正则表达式提供选项，如下所示：

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

i 选项使查询不区分大小写。
