Can @Component, @Repository and @Service annotations be used interchangeably in Spring or do they provide any particular functionality besides acting as a notation device? In other words, if I have a Service class and I change the annotation from @Service to @Component, will it still behave the same way? Or does the annotation also influence … Read more
I use Ubuntu and installed cURL on it. I want to test my Spring REST application with cURL. I wrote my POST code at the Java side. However, I want to test it with cURL.

Copied from the stacktrace: BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>() By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, … Read more

Error creating bean with name ‘entityManagerFactory’ defined in class path resource : Invocation of init method failed

@Autowired – No qualifying bean of type found for dependency

Try to annotate the ClientService (interface) with @Service. … Read more
