spring数据mongodb jpa find by id with composite id

我将mongodb与springboot结合使用,并且我有一个带有自定义 _id ,如是(在Java中):

@Document(collection="myEntity")
public class MyEntity {
    @Id
    private MyId id;
    private String field1;
    // getters, setters
    public static class MyId {
        private long field1;
        private String field2;
        private String field3;
        // getters, setters
    }

}

在mongo存储库中,我有一个 findById(MyId) save(MyEntity) MyId#id 字段被包装在 NumberLong .

db.myEntity.find()

将返回一个实体列表,如

{
  "_id": {
    "field1": NumberLong("1"),
    "field2": "a",
    "field3": "b"
  },
  "field1": "aa"
}

另一方面,在启用mongodb查询的调试日志记录后 findById 方法显示

使用查询完成 { "_id": { "field1": "$numberLong": "1", "field2": "a", "field3": "b" }, "field1": "aa" }

在mongo shell中:

db.myEntity.find({ "_id": { "field1": { "$numberLong": "1" }, "field2": "a", "field3": "b" }, "field1": "aa" }) 没有结果。

跑步 db.myEntity.find({ "_id": { "field1": new NumberLong("1"), "field2": "a", "field3": "b" }, "field1": "aa" }) 返回结果。

我怎样才能解决这个问题 query方法有效(返回给定id的预期结果)?
