springboot中，mybatis報錯Caused by: java.lang.ClassNotFoundException: tk.mybatis.mapper.generator.Mapper

springboot當中，映射不成功報錯。

報錯資訊：
Caused by: java.lang.RuntimeException: Cannot instantiate object of type tk.mybatis.mapper.generator.MapperPlugin
Caused by: java.lang.ClassNotFoundException: tk.mybatis.mapper.generator.MapperPlugin
           

解決辦法：檢查一下tk.mybatis.mapper插件，如果已經添加則嘗試修改一下版本。

<dependency>
    <groupId>tk.mybatis</groupId>
    <artifactId>mapper</artifactId>
    <version>4.1.5</version>
</dependency>
