Spring Data Mongo API PropertyReferenceException

问题

我正在使用 spring-boot（2.0.8.RELEASE）并连接到Mongo DB。我试图使用MongoTemplate按名称字段查找雇员文档。

>  - 在查询中：

    Collection<String> names = getNames(); 
    Query query = new Query(Criteria.where("name").in(names )); 
    mongoTemplate.find(query, Employee.class)

我遇到了 **找不到类型为Employee的$in属性！是否是指'_id'？** 异常。

为什么会出现这个问题？但响应没有影响，按预期工作。

**异常**：

I am using spring-boot(2.0.8.RELEASE) and connecting Mongo DB. I am trying to find employee document by name field using MongoTemplate.

> - In Query

Collection<String> names = getNames(); 
Query query = new Query(Criteria.where("name").in(names )); 
mongoTemplate.find(query, Employee.class)

I am facing No property $in found for type Employee! Did you mean '_id'? exception.

Why I am getting this issue ? But no impact in response, working as expected.
