SpringMVC 控制器默认支持GET和POST两种方式
在SpringMVC的controller中，@RequestMapping只写路径，不包含RequetMethod.GET和RequetMethod.POST，HttpServletRequest的getParameter(“*”)方法同时支持这两种方式。
1 @RequestMapping("savedata")
2 public @ResponseBody void savedata(HttpServletRequest req, HttpServletResponse resp) throws Exception {
3
4 String taskClass = req.getParameter("taskclass");
ServletRequest接口中对该方法的说明如下，可以从请求字符串（URL）和POST实体（通过getInputStream和getReader方法）中读取参数：
/**
* 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);
