- @RequestMapping(value="/pay",method = RequestMethod.POST)
- public String buildRequest(HttpServletRequest request){
- Map<String,String> parmMap=new HashMap<String,String>();
- //方式一：getParameterMap()，获得请求参数map
- Map<String,String[]> map= request.getParameterMap();
- //参数名称
- Set<String> key=map.keySet();
- //参数迭代器
- Iterator<String> iterator = key.iterator();
- while(iterator.hasNext()){
- String k=iterator.next();
- parmMap.put(k, map.get(k)[0]);
- }
- System.out.println("parmMap====="+parmMap.toString());
- //方式二：getParameterNames()：获取所有参数名称
- Enumeration<String> a = request.getParameterNames();
- String parm=null;
- String val="";
- while(a.hasMoreElements()){
- //参数名
- parm=a.nextElement();
- //值
- val=request.getParameter(parm);
- parmMap.put(parm, val);
- }
- System.out.println("parmMap=========="+parmMap);
- return "";
- }
