页面1：表单的action=login?method=login
页面2：表单的action=login?method=insert .....
然后通过method的值采用不同方法进行处理。
如下
public void doPost(HttpServletRequest request, HttpServletResponse response) {
String method = request.getParameter("method");
if ("login".equals(method)) doLogin(request,response);
else if("select".equals(method)) doSelect(request,response);
else if("insert".equals(method)) doInsert(request,response);
else if("delete".equals(method)) doDelete(request,response);
else if("update".equals(method)) doUpdate(request,response); }
public void doLogin(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
}
