@Autowired 不能注入dao的原因
1.Mapper.xml中namespace 不对
2.springboot启动类上包扫描路径有问题 @ComponentScan(basePackages = {"com.enxic.enxicdept8001.dao"}) .

Field deptDao in com.enxic.enxicdept8001.service.impl.DeptServiceImpl required a bean of type 'com.enxic.enxicdept8001.dao.DeptDao' that could not be found.
Action:

Consider defining a bean of type 'com.enxic.enxicdept8001.dao.DeptDao' in your configuration.
