java - Spring Data Mongo API PropertyReferenceException

Question

我正在使用 spring-boot(2.0.8.RELEASE) 并连接 Mongo DB。我正在尝试使用 MongoTemplate 按名称字段查找员工文档。

• 查询中

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

我面临找不到类型 Employee 的属性 $in！您指的是“_id”吗？例外。

为什么我会遇到这个问题？但响应没有影响，按预期工作。

例外
