SPRINGMVC setting global datetime JSON return format

For a partially returned datetime item, simply add @jsonserialize on the specified property to customize the return datetime format using a custom JSON conversion format

However, the above method is obviously not applicable for multiple DateTime fields returned in the project, and you need to customize the global datetime converter:

1. Configuration file:

<!--uses SPRINGMVC's own JSON conversion tool to support @responsebody annotation--><beanclass= " Org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter "><property name=" Messageconverters "><list><ref bean=" Mappingjacksonhttpmessageconverter "/></list></ Property></bean>   <!--avoid IE when performing Ajax, return json appears download file--><bean id= " Mappingjacksonhttpmessageconverter "Class=" Org.springframework.http.converter.json.MappingJackson2HttpMessageConverter "><property name=" Supportedmediatypes "><list><value>application/json;charset=utf-8</value><value>text /html;charset=utf-8</value></list></property><property name= "ObjectMapper" ><bean class= "Com.cml.mvc.framework.converter.DateTimeConverter" ></bean></property></bean>

Mostly custom Objectmapper in Mappingjacksonhttpmessageconverter

2. Download the required jar

               <dependency><groupId>com.fasterxml.jackson.datatype</groupId><artifactId> Jackson-datatype-joda</artifactid><version>${jackson.mapper}</version></dependency>

3, the realization of their own objectmapper

public class Datetimeconverter extends Objectmapper {private static final long Serialversionuid = 1l;public Datetimeconver ter () {This.registermodule (New Basejodamodule ()); This.configure (Serializationfeature.write_dates_as_timestamps, false);}}

Basejodamodule mainly modifies the Com.fasterxml.jackson.datatype.joda.JodaModule code by passing in the custom date format on the datetime registration converter.

Custom global datetime JSON format OK, but personally feel too complex, set a date format, to configure, to implement so many steps!looking for a simpler global configuration ...
