struts2总是返回input
最近做一个项目 注册的时候，点提交后返回的总是struts2配置文件中input的result页面。代码如下

如果没有进入相应方法，你就要考虑在拦截器设置断点了，
目测应该是mysql.insertMess方法失败了，你可以单步跟踪进入这个方法， --------------------编程问答-------------------- 必须错，String sql="insert into user"+"(userName,password,name,sex,birth,nation,edu,work,phone,place,email)"+"values("+"'"+userName+"'"+","+"'"+password+"'"+","+"'"+name+"'"+","+"'"+sex+"'"+","+"'"+birth+"'"+","+"'"+nation+"'"+","+"'"+edu+"'"+","+"'"+work+"'"+","+"'"+phone+"'"+","+"'"+place+"'"+","+"'"+email+"'"+")";
这句sql语句肯定有问题。看了下，每个参数都多一对单引号。 --------------------编程问答-------------------- 写sql语句要这么写吗，出个错，位置都找不到 --------------------编程问答-------------------- 自己单步调试一下吧，看看代码是如何运行的？ --------------------编程问答-------------------- 你的request用对了吗 --------------------编程问答-------------------- 如果你没定义input 却爆了带input的异常
可能是表单验证的问题 你注解掉action的方法 不进行表单验证就行 --------------------编程问答--------------------
把单引号删了 但还是那个问题 返回的依然是input。 我是新手 多谢帮助。 --------------------编程问答-------------------- 看了头晕 总结：稀烂 --------------------编程问答-------------------- 回复于： 2013-05-22 11:01:43
如果你没定义input 却爆了带input的异常
可能是表单验证的问题 你注解掉action的方法 不进行表单验证就行 --------------------编程问答-------------------- 你可以通过输出语句去查看下，执行到哪里给返回了。或者用debug，打上单点去进行调试。最好还是用debug去调试下吧！看看是那块的问题。 --------------------编程问答-------------------- 这是你Action中的方法中的问题。 --------------------编程问答-------------------- 做个注册 登录 有那么困难啊？好好学习ssh吧 --------------------编程问答-------------------- 哎哟。。你第二次注册的时候查询肯定有了。。当然返回input页面。
//判断是否用户名已存在，如果存在返回one
if(rs.next()){
sure="one";
} --------------------编程问答--------------------
你注册页面 登录名 name=“loginname” 数据处理页面又定义userName 明显不匹配 把register.jsp登录名 name="userName" 就ok了
补充：Java , Web 开发
