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。
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、mysql代码
1.创建数据库（logisticsDB）。
2.创建公司信息（tb_company）表。
