Also I have user and likes entity controller service and jpa repository. What am I doing wrong can you help me. I am new about spring boot.
CodePudding user response：
I would suggest starting with annotating your repos with the @Repository tag.
And looking at your error message, it looks like its having difficulty with the UserRepository specifically, you might want to start looking there.
CodePudding user response：
look at the exception again
Caused by: java.lang.IllegalArgumentException: Failed to create query for method public abstract com.project.blog.entities.User
com.project.blog.repositories.UserRepository.findbyUserName(java.lang.String)! No property 'findbyUserName' found for type 'User'!
You are trying to use a spring data query which does not exist or is invalid
the error is in UserRepository
Optional<User> findByUserName(String name);
or
Optional<User> findBy<FieldNameInCamelCase>(String name);
