ajax动态查询数据库数据并显示在前台的方法（ajax实现查询）没想到

@RequestMapping(value=”/findTotalUsers.do”,method=RequestMethod.GET)
public @ResponseBody Long findTotalUsers(){
ModelAndView modelAndView=new ModelAndView();
Long sum=personService.findTotalUsers();
System.out.println(sum+”………………………………”);
modelAndView.addObject(“sum”,sum);
return sum;
}

public Long findTotalUsers() {
return personDao.findTotalUsers();
}

public Long findTotalUsers() {
String hql=”select count(*) from Person”;
return (Long) this.getSessionFactory().getCurrentSession().createQuery(hql).uniqueResult();
}

<script src=”https://www.jb51.net/js/jquery-1.8.3.min.js” type=”text/javascript”></script>
<script type=”text/javascript”>
$(document).ready(
function ajaxRePost(url,params){
var message=””;
var options={
type:”GET”,
url:”${pageContext.request.contextPath}/person/findTotalUsers.do”,
data:{},
async:false,
success:function (msg) {
message=msg;
}
};
$.ajax(options);
alert(message);
// debugger;
$(“#count”).text(message);
return message;
}
)

</script>
