项目准备工作与环境搭建

一、画用例图usecase图

作用：让开发人员了解有那些角色要使用本系统，系统的用例（功能点），对整个系统的脉络有所了解。功能之间的关系，以及角色能操作哪些用例（功能）

采用Rationnal Rose（安装包大）：画顺序图、泳道图、类图、状态图（复杂业务有状态变迁图）

采用PowerDesigner（安装包小）：可画图，建立模型

二、系统功能结构图

采用visio软件：一般用来画网络结构图、建筑图

三、搭建框架

数据库————>持久层设计———>数据库访问Dao———>业务层Service————>控制层Controller————>视图层jsp

PD建模———PO持久对象，映射—————beans.xml配置文件———————springmvc-servlet.xml———web.xml，pom.xml



四、配置文件

1.sqlmapconfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 可配置mybatis数据库的配置，与Spring整合后可不需要配置，若配置的话此处优先加载 -->

</configuration>

2.mapping.xml（请根据需要重新修改）
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.itcast.jk.mapper.FactoryMapper">
<!-- 用来将pojo类和数据库的表对应，在这里写sql语句 -->
<!-- 数据库表映射 -->
<resultMap id="factoryRM" type="cn.itcast.jk.domain.Factory">
<id property="id" column="FACTORY_ID"/>
<result property="fullName" column="FULL_NAME"/>
<result property="factoryName" column="FACTORY_NAME"/>
<result property="contractor" column="CONTRACTOR"/>
<result property="phone" column="PHONE"/>
<result property="mobile" column="MOBILE"/>
<result property="fax" column="FAX"/>
<result property="cnote" column="CNOTE"/>
<result property="orderNo" column="ORDER_NO"/>
<result property="state" column="STATE"/>
</resultMap>

<!-- 查询所有记录 -->
<select id="find" parameterType="cn.itcast.jk.domain.Factory" resultMap="factoryRM">
select * from factory_c
where 1=1
</select>
</mapper>
