要求sqlSessionFactory和sqlSessionTemplate

概述

第一次出现在手动创建项目并使用 mybatis-flex 后测试启动项目，提示如下：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sysUserMapper' defined in file [D:\source\java\ecomm\ecomm-authority-center\target\classes\com\xdf\dao\SysUserMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

说明没有创建者两个对象，原因是依赖中缺少了 Hikari

代码

完整的依赖如下（微服务实战电商项目中制作 ecomm-authority-center ）

需要在 dao 的接口上使用注解 @Repository，同时在模块启动类头上指定扫描的包路径 @MapperScan(value = "com.xdf.dao")
