练习点设计：模糊查询、删除、新增

一、语言和环境

实现语言：JAVA语言。
环境要求：MyEclipse/Eclipse + Tomcat + MySql。
使用技术：Jsp+Servlet+JavaBean或SpringMVC + Spring + Mybatis。

二、实现功能

使用 SSM（Spring+SpringMVC+MyBatis）框架开发物流系统 - 公司信息管理模块，具体实现如下功能：

1，首页显示所有公司信息，如图 1 所示。

2，实现按公司名称模糊查询功能：在输入框中输入要查询的公司名称，点击“查找”按钮，显示相关的公司信息。

3，实现删除功能，删除之前弹出“删除确认”提示，删除成功后显示最新数据。效果图如图3所示。

4，实现增加公司信息的功能：点击首页上的“添加公司信息”，跳转到添加公司信息页面，页面效果如图4所示，完成增加功能，公司编号和公司名称必须输入。

三、数据库设计

1.创建数据库（logisticsDB）。

2.创建公司信息（tb_company）表，结构见表 1。
表1 公司信息表结构

四、推荐实现步骤

建立数据库和数据表，并且添加测试数据（至少添加5条测试数据）。
打开 Eclipse 或 Idea，创建 Web 工程，并创建相应包。
为工程添加 Spring、SpringMVC 和 MyBatis 支持。
在工程中创建实体类和与实体对应的 MyBatis 映射文件，正确配置MySQL 的 SQL 映射文件。
创建 Mapper映射器、业务类。在映射器或映射文件中编写 SQL 语句实现查询和增加操作。
创建 Controller 类，正确配置 SpringMVC 的配置文件。
正确配置 Spring 的配置文件，并有效管理 SQLSessionFactory。

五、实现代码

1.创建数据库（logisticsDB）。

2.创建公司信息（tb_company）表。
