mysql 取出的日期数据缺少时分秒

项目使用的数据库是mysql  持久层框架是hibernate  利用SQLQuery 获取日期的时候缺少时分秒   将 .addScalar("dealTS",StandardBasicTypes.DATE)

改成  .addScalar("dealTS",StandardBasicTypes.TIMESTAMP)，还有在模型的日期属性get  set方法 上加上注解@JsonSerialize(using = CustomJsonDateSerializer.class)

@JsonDeserialize(using = CustomJsonDateDeserializer.class)

CustomJsonDateSerializer   和 CustomJsonDateDeserializer  是自己写的继承JsonSerializer

public class CustomJsonDateSerializer extends JsonSerializer<Date> {
    @Override
    public void serialize(Date aDate, JsonGenerator aJsonGenerator, SerializerProvider aSerializerProvider)
            throws IOException, JsonProcessingException {

SimpleDateFormat dateFormat = new SimpleDateFormat(Constants.ISO8601_FORMAT);//"yyyy-MM-dd'T'HH:mm:ss"
        String dateString = dateFormat.format(aDate);
        aJsonGenerator.writeString(dateString);
    }
}

public class CustomJsonDateDeserializer extends JsonDeserializer<Date> {
    @Override
    public Date deserialize(JsonParser jsonparser,
            DeserializationContext deserializationcontext) throws IOException, JsonProcessingException {

SimpleDateFormat format = new SimpleDateFormat(Constants.ISO8601_FORMAT);//"yyyy-MM-dd'T'HH:mm:ss"
        String date = jsonparser.getText();
        try {
            return format.parse(date);
        } catch (ParseException e) {
            throw new RuntimeException(e);
        }

}
}
