When @Autowired doesn't work. There are several reasons @Autowired might not work. When a new instance is created not by Spring but by for example manually calling a constructor, the instance of the class will not be registered in the Spring context and thus not available for dependency injection.
It's a very common exception thrown when the BeanFactory creates beans of the bean definitions, and encounteres a problem. This article will explore the most common causes of this exception, along with the solutions.
The beans can be wired via constructor or properties or setter method. For example, there are two POJO classes Customer and Person. The Customer class has a dependency on the Person. @Autowired annotation is optional for constructor based injection.
If you want properly use @Autowired in your spring-boot application, you must do next steps: Add @SpringBootApplication to your main class. Add @Service or @Component annotation to class you want inject. Use one of two ways that you describe in question, to autowire.
Here last cause in your exception message:
Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException
Spring could not invoke the init method of your jpaMappingContext because a persistence exception occured - Something went wrong in the database.
So, Spring autowiring is actually working, but it cannot autowire your dependency because of a database problem that occurs when initializing one of the spring beans.
So something in the database or database settings changed since this code last worked. Analyze the full stack trace to find out the root cause of this issue - Which is a database problem.
