火车车次信息管理试题

本试题使用Jsp+Spring+Mybatis+Mysql+Maven等技术实现火车车次信息管理。

题目：火车车次信息管理

语言和环境

A、实现语言
Java
B、环境要求
JDK1.8、Eclipse、Tomcat7、Spring、Mybatis、Mysql、Maven

功能要求

使用JSP+Servlet+Spring+Mybatis实现火车车次信息管理功能，MySql作为后台数据库，功能包括车次信息浏览、火车车次信息详情和车次信息删除两大功能。具体要求如下：
（1）打开火车车次信息管理首页，以列表方式显示所有车次信息，页面列表要求实现隔行变色效果，如下图所示。

在这里插入图片描述
(2)单击“删除”链接可以进行火车车次信息删除，如果没有复选框被选中，当单击“删除”链接时需要提示“请选择车次！”信息，如下图所示。
在这里插入图片描述
（3）如果选中复选框，单击“删除”链接，执行删除车次信息操作，并根据删除结果给出相应的信息提示，如下图所示。在这里插入图片描述
点击确定后，跳转至车次信息列表页面，并显示更新后的车次列表信息，如下图所示。
在这里插入图片描述
（4）单击车次超链接，则跳转至指定车次的火车车次详情页面，如下图所示。
