创建一个包含 TextCriteria 和另一个字段的存储库查询

Question

我的数据库文档如下所示

@Document(collection = "campaign")
class Campaign {

    @Id
    var id: String? = null
    @Indexed
    @TextIndexed(weight = 1f)
    var name: String? = null
    var mediaLink: String? = null
    var imageLink: String? = null
    @TextIndexed(weight = 2f)
    var text: String? = null
    @TextIndexed(weight = 2f)
    var target: String? = null
    var ownerId: String? = null     // Who can modify this except "MANAGER"
    var useScope: String? = null    // Who can Use this Campaign [me, dl, all] i.e. Visibility
    @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
    var startOn: Date? = null       // @ this date the campaign becomes available and usable
    @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
    var expireOn: Date? = null      // @ this date the campaign becomes expired and not usable
    var timestamp: Date? = null
    ....

存储库

@Repository
interface CampaignRepository : MongoRepository<Campaign, String> {

    // page through results for full text query
    fun findAllBy(textCriteria: TextCriteria?, pageable: Pageable): Page<Campaign?>?

这实际上对用 @TextIndexed 注释的字段进行了很好的完整搜索问题是当我添加另一个过滤字段时，就像我想过滤 ownerId 整个查询要么不编译，要么在存储库函数中将 TextCriteria 更改为 String。业务逻辑要求我只显示所有者的数据

我试过了

// Expected parameter types: String , String not String, TextCriteria
fun findAllByOwnerId(ownerId: String?, textCriteria: TextCriteria?, pageable: Pageable): Page<Campaign?>?
// Property name must not be null or empty: 'findAllBy<EMPTY_PROPERTY>AndOwnerId'
un findAllByAndOwnerId(ownerId: String, textCriteria: TextCriteria?, pageable: Pageable): Page<Campaign?>?
// No property findAllOwnerId found for type Campaign! during Compiletime
fun findAllOwnerId(ownerId: String, textCriteria: TextCriteria?, pageable: Pageable): Page<Campaign?>?

我放弃！请协助

在Java的情况下，可以在仓库中使用@Query注解，在where子句中传递需要的字段，如spring-data的官方文档-mongodb

6.3.2。 MongoJSON基于查询方式和字段限制：https://docs.spring.io/spring-data/data-document/docs/current/reference/html/

By adding the annotation org.springframework.data.mongodb.repository.Query repository finder methods you can specify a Mongo JSON query string to use instead of having the query derived from the method name.

对于 and 子句中带有额外参数和参数的文本搜索，包括可分页参数

@Query("{$and:[ {'ownerId': ?0} , {'$text' : { '$search' : ?1}} ]}")
Page<Campaign> searchByByOwnerIdAndText(String ownerId, String keywords,
Pageable page);

上述查询的调试日志为：

2019-12-29 14:03:42.053 DEBUG 10998 --- [           main] o.s.d.m.r.query.StringBasedMongoQuery    : Created query Document{{$and=[Document{{ownerId=12}}, Document{{$text=Document{{$search=Krishna}}}}]}} for Document{{}} fields.

以上代码的详细内容，您可以访问Github页面：https://github.com/krishnaiitd/learningJava/blob/master/spring-boot-sample-data-mongodb/src/main/java/sample/data/mongo/repository/CampaignRepository.java#L11

希望这对您的 Kotlin 代码也有帮助。
