即使我已经在我的 ServiceImpl class 中自动装配实体，它仍然给我与自动装配相关的错误

Question

This is my Impl Class

@Service
public class TransactionServiceImpl implements TransactionService{

    @Autowired
    private Customer customer;

This is the error I am getting

Field customer in com.rewardsystem.AugustStore.service.TransactionServiceImpl required a bean of type 'com.rewardsystem.AugustStore.entities.Customer' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.rewardsystem.AugustStore.entities.Customer' in your configuration.

I tried to redo the steps but the problem still arises

Answer 1

I can see that you are trying to autowire Customer class that is Entity class (as per error message) and Entity classes are not beans (annotated with @Service , @Component , @Configuration , @Repository and @Bean ). So you can't use them as a dependency in other classes by using @Autowired annotation.

So please remove @Autowired annotation on top Customer class and create instance using new operator like this

Customer customer=new Customer();
