Record.kt

package com.t1.mmkqe.entity
import org.springframework.data.annotation.Id
import org.springframework.data.mongodb.core.mapping.Document

@Document(collection = "Record")
data class Record(
        @Id val name: String = ""
)

它不会生成Q类。但是，如果使用JPA @Entity批注，则可以。我尝试了许多带有pom / gradle的变体，不同的版本，并尝试了许多来自Internet的示例，但没有成功。

也许不可能。
