Answer 1

var requestdata= {
        pagenum:pageNum,
        pagesize:row
    };
$.ajax( {        
    url : '${ctx}/rest/my/userinfolist.json',
    contentType : 'application/json; charset=UTF-8',
    async : false,
    data :JSON.stringify(requestdata),
    type : 'post',
    success : function(data) {
         var mymsg=data.info;
                    }

public @ResponseBody Map purse_lock(@RequestBody MyPurse mypurse) {

String xxx=mypurse.getXX();
}
MyPurse  你要传的值的实体，实现get和set方法
