FAQ（10）：Type interface com.smbms.dao.UserMapper is not known to the MapperRegistry.

mybatis的mapper.xml文件有错！！

Log：

解决：

mapper的命名空间没填写完整！！（namespace漏了com.smbms.dao.）

原：

select id,userCode,userName,userPassword,gender,birthday,phone,address,userRole,createdBy,creationDate,modifyBy,modifyDate from employee where id = #{id} select * from employee

改：

select id,userCode,userName,userPassword,gender,birthday,phone,address,userRole,createdBy,creationDate,modifyBy,modifyDate from employee where id = #{id} select * from employee
