QUESTION
I am using inside of my application's controller autowired repository that works fine. But I also want to use my repo inside of another class. But when I invoke any method from the second class I get null pointer exception, looks like Autowiring is not working inside of this class. What am I doing wrong?

Q : Is it impossible to Autowire the same repo more than once?
A : You can call your spring beans as many as you want.
