After downloading and adding Topic package from earlier project when I am running it, i am getting error like "Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile". I have tried many things but I think in video there is nothing done explicitly. Please help me.
I dont see any topic about how to connect to external databases. Am I missing some thing.
You have fast internet and a fast machine :p
Thanks a lot Koushik for all the videos, they are really helpful, the best teacher :)There is something that I noticed. If the RestController class is not inside the same package (or subpackage) as the SpringBootApplication, then the controller is not picked by the MVC and my request to for eg. '/topics' returns me a 'not found'. I guess all RestControllers in the classpath are not picked up by the SpringBootApplication. (A complete classpath scan might not be happening)
Looking up the documentation specifies that I can specify the basepackages for the componentscan and things work fine when I do so. I realize it was the default same package + child packages that is being scanned when no basepackages are specified!
