SSM learning --spring road the next day _ a basis crud operations annotated with ioc

The previous and only slightly different, but will instead create objects bean annotations to create objects
one on the use of xml to achieve basic crud operations

First, the modified AccountDaoImpl

Injected with notes, no set method

Second, modify AccountServiceImpl

Injected with notes, no set method

Third, modify the file bean.xml

Constraints need to be modified, and the use of <context:component-scan base-package="com.itheima"></context:component-scan>designated use annotations to create the object to be scanned package

Fourth, the test class without modification, to run successfully
