Just had mock interview. It went great. Why ? Because I learn from JT. ❤ from London

Thank you for the video. Talking about bean ambiguity it is also possible to use @Primary, which is not straight up made for that, but it also an annotation, that allows you to explicitly configure priority for injected interface with multiple implementations

Great content. Revisiting basics with your videos, you are doing a wonderful job. One thing I noticed when I cross checked. As you said, @Autowired is by type. However, when both @Autowired and @Qualifier are used, then it becomes by Name and has the same effect as @Resource. Please check this and confirm 🙏
