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

<build>  
   <plugins>  
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-compiler-plugin</artifactId>  
            <configuration>  
                <source>1.8</source>
                <target>1.8</target>  
            </configuration>  
        </plugin>  
    </plugins>  
</build>

3.导入jar包

   </welcome-file-list>
   <!-- 上下文的位置 -->

       <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
