如何在spring中使用multiactioncontroller代替simpleformcontroller获得表单值

Answer 1

如果扩展MultiActionController，则只需执行request.getParameter（“parametername”）；。要利用setCommand()，请扩展SimpleFormController

更新（有关getParameter（）方法的更多理解）：

假设您有如下表单：

<form action="myController.html" method="post">
    Name : <input type="text" name="username" value="${param.username}" />
    <%--
       That ${param.username} will help pre-populating the value 
       of the text field with `username` parameter
    --%> 
</form>

public ModelAndView myControllerMethod(HttpServletRequest request, HttpServletResponse response) {
    String username = request.getParameter("username");
}
