SpringMVC 控制器默认支持GET和POST两种方式


1 @RequestMapping("savedata")
2     public @ResponseBody void savedata(HttpServletRequest req, HttpServletResponse resp) throws Exception {
4         String taskClass = req.getParameter("taskclass");


    * Returns the value of a request parameter as a <code>String</code>,
    * or <code>null</code> if the parameter does not exist. Request parameters
    * are extra information sent with the request.  For HTTP servlets,
    * parameters are contained in the query string or posted form data.
    * <p>You should only use this method when you are sure the
    * parameter has only one value. If the parameter might have
    * more than one value, use {@link #getParameterValues}.
    * <p>If you use this method with a multivalued
    * parameter, the value returned is equal to the first value
    * in the array returned by <code>getParameterValues</code>.
    * <p>If the parameter data was sent in the request body, such as occurs
    * with an HTTP POST request, then reading the body directly via {@link
    * #getInputStream} or {@link #getReader} can interfere
    * with the execution of this method.
    * @param name a <code>String</code> specifying the name of the parameter
    * @return a <code>String</code> representing the single value of
    * the parameter
    * @see #getParameterValues
    public String getParameter(String name);
