Mybatis与springboot项目启动时出现Field mapper in ‘xxx‘ required a bean of type ‘xxx‘ that could not be found

Mybatis与springboot项目，启动时报错，详细的错误如下：

Field mapper in 'xxx' required a bean of type 'xxx' that could not be found.
Action:
Consider defining a bean of type ‘xxx’ in your configuration.

原因是bean装配失败，springboot扫描时没有找到@Mapper对应的接口。

解决方法：
在启动类前加上：

@MapperScan(basePackages = { "mapper所在的包路径" }）

扫描mapper包下的所有mapper
