弹簧数据的MongoDB bulkOps不能没有序列化枚举

-1

我在我的模型枚举场，当我使用find方法来查询与此字段作为条件的一些数据，它的回报通缉。但是，当我使用bulkOps和EXCUTE的更新插入操作，它告诉我：
不能序列类com.timanetworks.tpc.vehicle.alarm.domain.enums.FaultType
弹簧数据的MongoDB bulkOps不能没有序列化枚举

我尝试添加enum的name（）方法来解决这个问题，并且它是成功的！但我仍然不明白为什么？有人知道吗？

我的模式是这样的：

@Document(collection = "FaultSnapshot") 
@TypeAlias("faultSnapshot") 
public class FaultSnapshot extends BaseDocument { 
    private FaultType type; 
    private String vin; 
    private Integer faultLevel; 
    private Boolean isFault; 
    private Date time; 
    ...setters and getters...

和FaultType是一个枚举：

public enum FaultType { 
    FAULT_EMS,  
    .... 
}

，这是找到代码：

Query query = new Query(); 
    if (type != null) { 
     query.addCriteria(where("type").is(type)); 
    } 

    Pageable pageable = new PageRequest(pageIndex - 1, pageSize); 
    Sort sort = new Sort(Sort.Direction.DESC, "time"); 
    List<FaultHistory> histories = template.find(query.with(pageable).with(sort), 
      FaultHistory.class); 
    return new Page<>(count, histories);

这是bulkOps代码：

public void upsertSnapshot(Collection<FaultSnapshot> snapshots) { 
    BulkOperations bulk = template.bulkOps(BulkOperations.BulkMode.UNORDERED, FaultSnapshot.class); 
    for (FaultSnapshot snapshot : snapshots) { 
     Query query = new Query(); 
     query.addCriteria(where("vin").is(snapshot.getVin())); 
     query.addCriteria(where("type").is(snapshot.getType().name())); 

     Update update = new Update() 
       .set("isFault", snapshot.getFault()) 
       .set("faultLevel", snapshot.getFaultLevel()) 
       .set("time", snapshot.getTime()) 
       .set("vin", snapshot.getVin()) 
       .set("type", snapshot.getType().name()); 

     bulk.upsert(query, update); 
    } 

    bulk.execute(); 
}

最后，这是错误堆栈：

这其实是一个错误（DATAMONGO-1678）在Spring数据MongoDB中。它已被固定为1.9.12,1.10.5和2.0.0.RC1。

在编写没有提到版本的时间已被释放。

呜了，谢谢。我觉得西港岛线使用枚举的名称方法的littile时间。 –
