{"data": { "bidprice": 26.8, "fundnames": null, "offerprice": 27.4, "fundid": "123456789", "funddescription": "high risk equity fund", "lastupdated": "2015-08-25t15:48:57" }} 

i want remove null objects(fundnames) returned response looks like

 {"data": {   "bidprice": 26.8,   "offerprice": 27.4,    "fundid": "123456789",    "funddescription": "high risk equity fund",    "lastupdated": "2015-08-25t15:48:57"  }} 

my beans.xml

<?xml version="1.0" encoding="utf-8"?> <mvc:annotation-driven/> <context:component-scan base-package="com.blog" />  <bean class="org.springframework.web.servlet.mvc.annotation.defaultannotationhandlermapping" /> <bean class="org.springframework.web.servlet.view.json.mappingjacksonjsonview">     <property name="contenttype" value="application/json"/> </bean>  <bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter">     <property name="messageconverters">          <util:list id="beanlist">             <ref bean="jsonmessageconverter"/>         </util:list>         </property> </bean> <bean id="jsonmessageconverter" class="org.springframework.http.converter.json.mappingjacksonhttpmessageconverter"/>
