@H_404_1@使用Spring Boot 1.4.4.RELEASE,将RequestBody保存到MongoDB,如下所示：
@H_404_1@
{
"startTime" : NumberLong("1483542955570"),"startDate" : ISODate("2017-01-04T15:15:55.570Z"),"endTime" : NumberLong("1483542955570"),"endDate" : ISODate("2017-01-04T15:15:55.570Z")
}
public "startDate" : { "$date" : "2017-01-04T15:15:55.570Z"}
java.lang.RuntimeException: Error parsing mongoDoc to Pojo : errorMessage : {Can not deserialize instance of java.util.Date out of START_OBJECT token at [Source: {

},"endTime": 1483542955570,"endDate": {

}}; line: 1,column: 381] (through reference chain: com.gofynd.engine.mongo.models.RuleWithDataVO["validity"]->com.gofynd.engine.mongo.models.ValidityVO["startDate"])}
最佳答案
反序列化到Date Jackson期望字符串如“2017-01-04T15：15：55.570Z”.相反,它会看到另一个对象的开始(JSON中的{char)因此异常.
@H_404_1@考虑指定您的Pojo类和另一个类似于此的MongoDate类：
@H_404_1@
class MongoDate {
@JsonProperty("$date")
Date date;
}
class Pojo {
long startTime;
long endTime;
MongoDate startDate;
MongoDate endDate;
}
class Pojo {
long startTime;
long endTime;
@JsonDeserialize(using = MongoDateConverter.class)
Date startDate;
@JsonDeserialize(using = MongoDateConverter.class)
Date endDate;
}
class MongoDateConverter extends JsonDeserializer
