报错：tk.mybatis.mapper.provider.EmptyProvider中缺少selectOne方法!

SpringBoot引入mapper-spring-boot-starter 之后，开发模式热重载下报错

tk.mybatis.mapper.provider.EmptyProvider中缺少selectOne方法!

解决步骤：

1、新建一个配置文件 src/main/resources/META-INF/spring-devtools.properties

#业务包，依赖的其他业务组件（避免热部署的devtools和通用mapper的冲突）
restart.include.hifi=/hifi-[\\w-\\.\\d]+.jar
restart.include.mybatis=/mybatis-[\\w-\\.\\d]+.jar
restart.include.mapper=/mapper-[\\w-\\.\\d]+jar
restart.include.pagehelper=/pagehelper-[\\w-\\.\\d]+jar

mapper版本过低也会报错

Caused by: org.apache.ibatis.builder.BuilderException: 
Error invoking SqlProvider method 
(tk.mybatis.mapper.provider.base.BaseSelectProvider.dynamicSQL).  
Cause: java.lang.InstantiationException: 
tk.mybatis.mapper.provider.base.BaseSelectProvider

2、需要升级版本(1.2.4->2.0.0)

    tk.mybatis
    mapper-spring-boot-starter
    2.0.0

参考 tk.mybatis.mapper.MapperException: tk.mybatis.mapper.provider.EmptyProvider中缺少selectOne方法!
