SPRINGMVC Unified settings return to the front-end JSON time format

When we use the @ResponseBody annotations in SPRINGMVC to return JSON data to the front end, we find that time is always a bunch of numbers, and here are two ways to solve time-format problems.

1. Use annotations on the Get method of the Time field

@JsonFormat (pattern = "Yyyy-mm-dd HH:mm:ss", timezone = "gmt+8")

The time that the frontend gets is the time format you set. But this method is a physical activity, you need to add this annotation to each time Type field.

2 to set the time format by configuring the JSON converter in the spring XML configuration file

 @Component ("jacksonobjectmapper " ) The ref-pointing name in the configuration file corresponds to  public  class  Customobjectmapper extends   Objectmapper { private  static  final  long  serialversionuid = 1l; @PostConstruct  public  void  afterpropertiesset () throws   Exception {simpledateformat sdf  = new  SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss"  

XML file configuration for spring

<Mvc:annotation-driven>        <mvc:message-converters>                 <Beans:beanclass= "Org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">                <Beans:propertyname= "Objectmapper"ref= "jacksonobjectmapper"/>                < Propertyname= "Supportedmediatypes">                    <List>                        <value>Application/json;charset=utf-8</value>                    </List>                </ Property>            </Beans:bean>                 </mvc:message-converters>    </Mvc:annotation-driven>
