Struts2 ext 登陆验证
文章分类:Web前端 主要功能：使用ext form提交表单
?????????????? 由struts2 action处理逻辑，并返回json数据
?????????????? ext接收返回的json数据给出提示
?????????????? 使用spring管理bean
??????????????
主要配置： 引入struts的json插件jar包，在struts的配置文件中配置为extends="json-default"。
???????????????????????? action需返回如"{success:true,msg:'返回信息'}"的JSON字符
1?? 表单所在jsp(user_regist.jsp)
