Java遍历解析URL类型字符串中参数

    public static void main(String[] args) {
        String str="&emailCheckURL=447&useremail=vip@cxais.com&porm=p";
        String[] splitURL=str.split("&");
        Map<String,Object> mapParam=new HashMap<String,Object>();
        for(String s:splitURL){
            if(s.indexOf("=")>0){
                mapParam.put(s.substring(0, s.indexOf("=")),s.substring(s.indexOf("=")+1, s.length()));
            }
            
        }
        for(Map.Entry<String, Object> entry:mapParam.entrySet()){
            System.out.println(entry.getKey()+"~~~"+entry.getValue());
        }
        
    }
