         <artifactId>spring-jdbc</artifactId>
         <version>5.1.9.RELEASE</version>
     </dependency>
 </dependencies>

 

2. maven资源过滤(pom.xml)

 <build>
     <resources>
         <resource>
             <directory>src/main/java</directory>
             <includes>
                 <include>**/*.properties</include>
                 <include>**/*.xml</include>
             </includes>
             <filtering>false</filtering>
         </resource>
         <resource>
             <directory>src/main/resources</directory>
             <includes>
                 <include>**/*.properties</include>
                 <include>**/*.xml</include>
             </includes>
             <filtering>false</filtering>
         </resource>
     </resources>
 </build>

 

3.完整目录

pojo/service/comtroller/dao

4. 新建 mybatis-config.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></configuration>

 

5.新建applicationContext.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

 

2.mybatis层

1.新建database.properties 数据库配置文件

 jdbc.driver=com.mysql.jdbc.Driver
 # useSSL属性为是否使用ssl安全链接,可能导致无法访问数据库
 jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
 jdbc.username=root
 jdbc.password=123

 

2.更改mybatis核心配置文件 mybatis-config.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>
     
     <!--别名,为了使用model类时方便,不需要写全名-->
     <typeAliases>
         <package name="com.mvc.pojo"/>
     </typeAliases>
     
     <!--绑定mapper映射文件-->
     <mappers>
         <mapper resource="mappers/userMapper.xml"/>
     </mappers></configuration>

 

3.实体类编写

4.dao层编写,mapper接口

5.编写对应的mapper.xml配置文件

 <?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>
 <select id="selectAllUser" resultType="User">
        SELECT * from user
     </select>
 </mapper>

 

6.编写service层以及实现借口(service层调用dao层)

Spring层

1.编写spring-dao.xml配置文件,用来整合mybatis
