Just learning Shiro, and then want to integrate him into spring MVC.
I've been doing it for a long time, but I haven't been able to annotate it with @Autowired
In the end, I found that annotations are only available in the Controller. I checked a lot of information, but I didn't fully understand it. Finally, I suddenly found that after referring to Shiro, the Controller layer cannot use the bean of the entity class, and must be implemented through the interface.
For example: My previous UserService was directly a class, and then annotated with @Service, this will not work
You must first write a UserService interface, and then write a UserServiceImpl to integrate the UserService interface
Then, my Controller can @Autowired UserService
