错误描述:

Description:

Field xxxDao in com.abc.web.service.impl.PostServiceImpl required a bean of type 'com.abc.core.dao.PostDao' that could not be found.

Action:

Consider defining a bean of type 'com.abc.core.dao.PostDao' in your configuration.

问题描述:

xxxDao、xxxDaoImpl在module(abc-core)

xxxService、xxxServiceImpl在module(abc-web)

解决方法

1. @ComponentScan("com.abc")

2. ​​​​​​@ComponentScan(basePackages = {"com.abc.core", "com.abc.web"})

3. @SpringBootApplication(scanBasePackages = "com.abc")

三种方法都无效，求老司机解答？跪谢。。。
