springMVC 与异步提交错误 请高手来分析分析帮帮我这个菜鸟

[qq_32474817]

页面
alert(rows.uid);
if(r){
$.post("user/deleSystem.do", {
"uid": rows.uid,
method : 'deleSystem'
},function(data){

}, "text");
}
rows.uid 是个数字
服务器端
@ResponseBody
@RequestMapping(value="/studentsAll.do",method=RequestMethod.POST)
public ModelMap StudentsAll(int pageNo,int pageSize,ModelMap map){
Page<Sys_students> pages = servlce.allstudents(pageNo, pageSize, null);
map.addAttribute("rows", pages.getData());
map.addAttribute("total", pages.getTotal());
return map;
}

报错：严重: Servlet.service() for servlet test threw exception
java.lang.IllegalStateException: Ambiguous handler methods mapped for HTTP path '/user/deleSystem.do': {public void com.spring.controller.TextController.deleSystem(int,org.springframework.ui.ModelMap), public void com.spring.controller.TextController.demandmyUserName(java.lang.String,int,org.springframework.ui.ModelMap)}. If you intend to handle the same path in multiple methods, then factor them out into a dedicated handler class with that path mapped at the type level!

value在服务器出现多个了 就报了如上的错误

[街头小贩]

1. 你请求的: /deleSystem.do 而你贴的: /studentsAll.do 2. @ResponseBody还返回一个ModelMap有什么用? 3. StudentsAll(int pageNo,int pageSize,ModelMap map){} 前两个参数怎么来的.好好看看spring的手册，上面写的很全面
