spring boot整合mybatis框架及增删改查（jsp视图）

工具：idea、SQLyog

版本：springboot1.5.9版本、mysql5.1.62

第一步：新建项目

　　　　　

　　　　　

第二步：整合依赖（pom.xml）

     <dependencies>

         <!--文件上传 -->

             <version>1.1.2</version>
         </dependency>

     </dependencies>

第三步：配置application.properties文件

server.port=8086
#编码格式
web.encoding=UTF-8
#热部署自动
spring.devtools.restart.enabled=true
#静态资源
spring.mvc.static-path-pattern=/static/**
#视图解析器
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp
#数据源
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/wutongvip?characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
#配置mybatis
#mybatis映射文件路径 路径一定要对应好 如放在static下，classpath:static/mapping/*.xml
mybatis.mapper-locations=classpath:mapping/*.xml
#设置pojo别名
mybatis.type-aliases-package=com.buba.nusmanager.pojo
#驼峰映射开关
mybatis.configuration.map-underscore-to-camel-case=true

#pagerHelper分页配置
#数据库方言
#pagehelper.dialect=mysql
#分页合理的 pagerNum<1时 查询结果为为pageNum=1
pagehelper.reasonable=true
#支持从方法的参数中获取页码信息
pagehelper.support-methods-arguments=true
#默认值0
pagehelper.page-size-zero=true
#请求是所带的参数
pagehelper.params==count=countsql

#打印mybatis的sql语句
logging.level.com.example.wutongdemo.maper=debug
logging.file=springboot.log

#解决图片上传问题
picurl=D:/imgs/

spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/, classpath:/static/, classpath:/public/,file:D:/imgs/

CommodityMaper.xml：

<?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="com.example.wutongdemo.maper.CommodityMaper">

    <select id="findAllCommodity" resultType="com.example.wutongdemo.pojo.Commodity">
        SELECT * FROM `user`
    </select>

</mapper>

第四步：项目整体架构图

　　　　　　

第五步：测试运行

　　　　

注意事项：

1. mapper层加入@Repository注解，service实现类加入@Service注解；
2. maper.xml文件要和application.properties文件路径对应，maper.xml的namespace属性等于maper层接口绝对路径；
3. spring boot项目启动类上加入@MapperScan("maper层全路径")。

以上总结希望可以帮到大家，有什么问题及时反馈。
