jquery向后台取值的有关问题

jquery向后台取值的问题
我用的是spring   mvc     我后台编码是
@Controller
public   class   BasysController   {
@Autowired
private   UserssDAO   userDAO;
@RequestMapping( "/basy/getJson ")
public   ModelAndView   getJson(HttpServletResponse   response,HttpServletRequest   request)   throws   IOException{  
request.setCharacterEncoding( "UTF-8 ");
response.setCharacterEncoding( "UTF-8 ");
response.setContentType( "application/json ");
                //提取数据
ReadFrData   rfd   =   new   ReadFrData();
List <String>   l   =   rfd.getDataFromMysql();
//把集合转化为JSON格式的数组
String   data   =   JsonUtil.listToJson(l);
System.out.println(data);

PrintWriter   out   =   response.getWriter();
out.print(data);
return   new   ModelAndView( "manager/Autocomplete ");
}
}
请问下前台页面用JQUERY   怎么提取data   的值...  

------解决方案--------------------------------------------------------
java的我就不清楚了，mvc应该有重写后这个方法的url地址什么的吧。。可以通过浏览器直接访问的
------解决方案--------------------------------------------------------
url 你这样写“../manager/Autocomplete.jsp”
