Java mongo操作spring mongo批量操作执行异常（codeConfigurationException:Can'；找不到类的编解码器）

我试图使用SpringMongo操作类在mongodb中执行批量操作

以下是我的POJO课程：

@Document(collection = "location_settings_mst")
public class LocationSettingsEntity {
    @Id
    private String id;
    @Field("userId")
    private String userId;
    @Field("location")
    private List<LocationSettingEntity> locationSettings = new LinkedList<>();
    // Getters and Setters
}

public class LocationSettingEntity {
    @Field("name")
    private String name;
    @Field("latitude")
    private double lat;
    @Field("longitude")
    private double lon;
    @Field("geoPoint")
    private String geoPoint;
    // Getters and Setters
}

我试着调试，发现com.mongodb库检查数据类型的编解码器，如果找不到，就会抛出错误。据我所知，spring mongo操作能够处理POJO

我不明白我错过了什么。请帮忙

从技术上讲，您可以编写自定义编解码器。 我这样做了，但它没有工作，然后我跳入Mongo驱动程序代码，似乎有一个错误

看来他们犯了个错误- com.mongodb.DBCollection#DBCollection（java.lang.String、com.mongodb.DB、com.mongodb.operation.OperationExecutor）

在这里，他们从默认的静态编解码器注册表中设置集合编解码器，因此该注册表将永远无法获取人们编写的自定义编解码器。互联网上有很多ppl都被这个问题困扰着

但是，可以通过将更新负载转换为DBObject来解决这个问题，DBObject可以使用com.mongodb.basicdbobobjectbuilder类来完成，而且非常简单。不确定性能是否会像编解码器一样好。我正在考虑编写自己的dbobjectbuilder，它将为我提供性能。因为我认为最基本的是使用json

Update update = new Update();
update.pushAll("location", list.stream().map(BasicDBObjectBuilder.start().add(//key,value pairs).get()).collect(Collectors.toList()).toArray());
bulkOps = bulkOps.updateOne(query, update);
bulkOps.execute();
