spring mvc 返回的json去掉null

在springmvc.xml中添加如下：

           
               
                   
                       NON_NULL
                   
               
           
        

但是有个问题就是以json作为参数的接口，bean必须和json对应好，否则会报

CompetitionRoadUser["IDNumber"]);

 nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "IDNumber" (class com.neusoft.geexek.web.

com.neusoft.geexek.web.enroll.bean.CompetitionRoadUser["IDNumber"])

我传递的json格式的参数数：

{"remark":"[]","userName":"123123123","callPhone":"123123123123","typeOfID":"身份证","IDNumber":"123123123123123","gender":0,"roadId":8553,"userPayRelations":[],"idNumber":"123123123123","isIns":2}

去除这种错误的办法：在bean上添加

@JsonIgnoreProperties(ignoreUnknown = true)
