Springのデータベース接続でのエラー

# データベースでの一連の流れでのエラー

[教材にさせていただいてました](https://qiita.com/yu_eguchi/items/5bdda6f6ee7baf441870#mybatis%E3%81%A8%E3%81%AF)

進めていて、URLに接続したときにエラー

```

## 対処した内容
mvc-config.xmlファイルがしっかり記述できていなかった

```xml:mvc-config.xml
<!-- エラー箇所のみ記載 -->

<!-- Uncomment and your base-package here:   -->
<context:component-scan base-package="jp.co.kenshu.controller"/>
```

ここの指定が間違えていたので、変更したらなおった

```xml:mvc-config.xml

<!-- Uncomment and your base-package here:   -->
<context:component-scan base-package="jp.co.kenshu"/>
```
