Scheme

1. Customizing a Jackson JSON conversion class

 Public classLongtostringadapterextendsObjectmapper {Private Static Final LongSerialversionuid = 4402127997078513582L;  PublicLongtostringadapter () {Super(); Simplemodule Simplemodule=NewSimplemodule (); Simplemodule.addserializer (Long.class, tostringserializer.instance);        Simplemodule.addserializer (Long.type, tostringserializer.instance);  This. Registermodule (Simplemodule); }}

2, configure to the Springmvc file can be

  <Mvc:annotation-drivenConversion-service= "Conversionservice">        <mvc:message-converters>             <Beanclass= "Org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">                 < Propertyname= "Objectmapper">                      <!--<bean class= "Com.fasterxml.jackson.databind.ObjectMapper" > -                    <Beanclass= "MyPackage." Longtostringadapter ">                        < Propertyname= "DateFormat">                              <Beanclass= "Java.text.SimpleDateFormat">                                  <Constructor-argtype= "Java.lang.String"value= "Yyyy-mm-dd HH:mm:ss" />                              </Bean>                          </ Property>                      </Bean>                  </ Property>           </Bean>        </mvc:message-converters>      </Mvc:annotation-driven>
