struts2表单重复提交

一、在页面的form表单中添加令牌属性

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>


    


<s:form action="/form/form.action">
  <s:textfield name="name">s:textfield>
  <s:token>s:token>
  <s:submit>s:submit>
s:form>

二、配置token拦截器

name="form" extends="struts-default" namespace="/form">
    
    name="form" class="form.Form" method="form">
        
        name="token">
        name="defaultStack">
        /index.jsp
        name="invalid.token">/form.jsp
