spring + springmvc + mybatis整合以及一些常见问题(一)

写此文章提醒下自己 下次记得配置web.xml
首先导包

 <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
 </dependency>
 <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
            <scope>provided</scope>
 </dependency>

</dependency>

引入spring相关jar
