本文介绍了一个基于Spring MVC框架实现的用户管理系统，该系统包括用户登录验证、获取用户列表、删除用户及添加用户等功能。通过使用MyBatis进行数据持久化操作，并实现了文件上传功能。

            user.setTx(txName);

Give me your best shot. I’m not gonna give up, I will never give in.
你最好给我狠狠的一击，但是我绝不会因此放弃，也绝不可能屈服。
投稿人的话：这是来自“keep it coming”歌里的歌词，看到这句话时，总能让丧气的我瞬间充满斗志，脑子里想着白天遇到的糟心事，心里说“来啊你们，还能把我咋滴了！”其实歌词后面还有一句我也很喜欢：Take every lemon life hands out, and make some lemonade. 我一直相信生活会因为我们变好一点就会对我们更好。
