无法通过Camel将日期字段保存为mongo db中的ISO日期？

时间：2017-11-08 07:04:40

标签： java mongodb date apache-camel spring-camel

我喜欢这样：

@Document(collection = "data")
public class DataPoint {
    @Id
    private String id;
    private LocalDateTime createdDate;
    ....
}

在某些代码库中我有以下代码：

@Autowired
private ProducerTemplate producerTemplate;

...

final List<DataPoint> dataPoints =....
producerTemplate.sendBody("mongodb:mongoBean?database=" + mongoDataConfiguration.getDatabase()
                                    + "&createCollection=true&operation=insert&collection=" + mongoDataConfiguration.getDataPointCollection(), 
        dataPoints);

但是当我在数据库中打开集合时，我会看到这样的日期字段：

"createdDate" : {
                "month" : "NOVEMBER",
                "year" : 2017,
                "dayOfMonth" : 7,
                "dayOfWeek" : "TUESDAY",
                "dayOfYear" : 311,
                "monthValue" : 11,
                "hour" : 17,
                "minute" : 55,
                "nano" : 259000000,
                "second" : 21,
                "chronology" : {
                        "id" : "ISO",
                        "calendarType" : "iso8601"
                }

但我想存储mongoDB可识别的通常ISO日期。它应该是这样的：

ISODate("2017-11-06T12:47:51.720")

我是如何尝试解决此问题的？

我看了this topic：

因此我创建了一个自定义序列化器：

public class IsoDateSerializer extends JsonSerializer<DateTime> {
    @Override
    public void serialize(DateTime value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
           jgen.writeStartObject();
        serializeContents(value.toDate(), jgen, provider);
        jgen.writeEndObject();
    }
    private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        jgen.writeFieldName("$date");
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
        String formattedDate = formatter.format(value);
        jgen.writeString(formattedDate);
    }
}

并正确注册：

@JsonSerialize(using = IsoDateSerializer.class)
public DateTime getCreatedDate() {
    return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC)));
}

但它抛出异常：

然后我需要写：

 .marshal(jackson) 
        .convertBodyTo(String.class)

但看起来producerTemplate没有合适的API。

好的，我理解异常的原因。 @ Neil Lunn说这是因为名字以$开头 - 保留。

我创建了一个主题Could not save date field as ISO date in mongo db via Camel (Caused by: java.lang.IllegalArgumentException: Invalid BSON field name $date)

根据我试图做的@ Neil Lunn建议

a）在模型中返回日期：

public DateTime getCreatedDate() {
        return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC))).toDate();        
    }

导致将日期保存为NumberLong

b）尝试在序列化程序中使用$date更改myDate，但这会导致像往常一样保存日期

с）

此外，我尝试在前一个问题中根据@ Neil Lunn建议更改序列化程序中的日期格式：

private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
    jgen.writeFieldName("mydate");
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
    String formattedDate = formatter.format(value);
    jgen.writeString("ISODate("  +formattedDate + ")");
}

但它仍然不起作用，我看到了：

"createdDate" : {
                "mydate" : "ISODate(2017-11-08T13:15:06)"
        },

在mongo-shell中

请帮忙解决这个问题？

P.S。

当我现在使用spring-data-date存储而没有额外的动作时
