java 通过request.getParameterMap()获取前台传入参数

public Map<String, Object> getData(HttpServletRequest request) throws Exception{
    Map<String,Object> map = new HashMap<String, Object>();
    Map<String, String[]> mapData = request.getParameterMap();
    Iterator it = mapData.keySet().iterator();
    while (it.hasNext()){
        Map.Entry<String, String[]> entry = (Map.Entry<String, String[]>) it.next();
        for (String v: entry.getValue())
        map.put(entry.getKey(), ToolUtil.isEmpty(v)?null:v);
    }
    return map;
}
