1.创建数据库
2.创建spring的maven项目
• 解决web.xml缺失
o 项目名右击---Java EE Tools-----Generate .....
• 解决JDK版本问题,在POM中添加并update Maven

<url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>
5.建立包结构
根据spring配置文件和springmvc配置文件中的扫描包建立对应包本例包结构:
• cn.CHEEMIN.springmvc
o controller
o service
o pojo
o mapper
6.创建实体类与mapper接口与xml
• 根据数据库表结构创建pojo实体类,并生成getter和setter
数据库中bigint对应Long
• 根据pojo实体类创建mapper接口与mapper.xml
mapper.xml模板:
<?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.cheemin.springmvc.mapper.BaseDictMapper">
<select id="getBaseDictList" parameterType="string" resultType="cn.cheemin.springmvc.pojo.BaseDict">
SELECT * FROM base_dict WHERE dict_type_code = #{dict_type_code}
</select>
</mapper>
7.运行前准备
项目中加入jsp、css、fonts、js等前端
• jsp放入WEB-INF
• 其他放入webapp
• 将分页功能utils包添加到与mapper同级目录下。
o 包括分页标签实现类l以及Page实体类
• 分页标签tld文件夹放入jsp同级目录
o 分页标签tld文件中的tag-class指明为分页标签类的全限定名
8.编写controller层
• 在类名前加@controller注解
o 在controller内部方法前加@RequestMapping("浏览器访问路径(去除项目名称)")
o 内部方法写完之后,项目即可初步运行。通过前一步的访问路径,可以调用一些方法。
o controller成员变量使用@Autowired注入
• 功能实现:controller调用service,service调用mapper
9.编写service层
@Service声明JavaBean
@Transactional开启事务
成员变量使用@Autowired
10.编写mapper
在sqlyog中编写能成功执行的sql语句后,复制到mapper.xml中修改
