配置mybaits的一些坑

参考博客置顶：

然后还有个坑爹的 mysql8.0要加useSSL=false

还有就是那个我的ibaits导不进来的一个问题

虽然这个博客说的对，但是我的估计是缓存问题，我把idea重启一下就好了。但是花了我一个早上的时间……

然后就是导入mybaits的xml的时候，那个网站好像会爆红，我直接就alt+enter 直接修复了……

其它没啥问题，吧自己的配置文件写一下在这边吧

文件目录：

 然后，父文件的pom.xml

        </dependency>




    </dependencies>
    <!--在build中配置resources，来防止我们资源导出失败的问题-->
    <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>

            <resource>

            </resource>
        </resources>
    </build>


</project>

然后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>
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/mybatis?useSSL=true&amp;useSSL=false&amp;useUnicode=true&amp;characterEncoding=UTF-8"/>
                <property name="username" value="root"/>
                <property name="password" value="123456"/>
            </dataSource>
        </environment>
    </environments>

    <!--每一个mapper。xml都需要再mybatis核心配置文件中注册-->
    <mappers>
        <mapper resource="com/kuang/dao/UserMapper.xml"/>
    </mappers>
</configuration>

然后 再是Mapper映射

<?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.kuang.dao.UserDao">
    <select id="getUserList" resultType="com.kuang.pojo.User">
      select * from mybatis.user
   </select>

</mapper>
