HttpServletRequest获取请求参数

通过HttpServletRequest接收请求来的参数，

get请求

public class controller1 {
 ???@RequestMapping(value = "/", method = {RequestMethod.POST})
 ???public String con001(HttpServletRequest request) throws IOException {
 ???????Map<String, String> param = getAllRequestParam(request);
 ???????String queryString = request.getQueryString();
 ???????String user = request.getParameter("user");
 ???????String pass = request.getParameter("pass");
 ???????System.out.println(user);
 ???????System.out.println(param);
 ???????return "hello";
 ???}

post请求

先获取到参数名的集合，在组装到Map里

private Map<String, String> getAllRequestParam(final HttpServletRequest request) {
 ???Map<String, String> res = new HashMap<String, String>();
 ???Enumeration<?> temp = request.getParameterNames();
 ???if (null != temp) {
 ???????while (temp.hasMoreElements()) {
 ???????????String en = (String) temp.nextElement();
 ???????????String value = request.getParameter(en);
 ???????????res.put(en, value);
 ???????}
 ???}
 ???return res;
}
