Spring-Boot错误创建bean，ca启动失败。 50％的时间

Question

I have a Spring-Boot application, where the startup sometimes fails, and sometimes, without changing anything in the Code, it works. Here's the Error:

Parameter 1 of constructor in ch.post.pf.quick2lunch.business.service.OrderService required a bean of type 'ch.post.pf.quick2lunch.repository.MenuOrderRepo' that could not be found.


Action:

Consider defining a bean of type 'ch.post.pf.quick2lunch.repository.MenuOrderRepo' in your configuration.

06-Jul-2018 10:41:34.287 SCHWERWIEGEND [RMI TCP Connection(3)-127.0.0.1] org.apache.catalina.core.ContainerBase.addChildInternal ContainerBase.addChild: start: 
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/quick2lunch]]
at org.apache.catalina.util.LifecycleBase.handleSubClassException(LifecycleBase.java:441)
at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:198)

The Annotaions should be okay.

Here's The MenuOrderRepo:

@Repository
public interface MenuOrderRepo extends JpaRepository<MenuOrder, Long> {
}

And here's the OrderService:

@Service
public class OrderService {

private final OrderRepo orderRepo;

private final MenuOrderRepo menuOrderRepo;

@Autowired
public OrderService(final OrderRepo orderRepo, final MenuOrderRepo menuOrderRepo) {
    this.orderRepo = orderRepo;
    this.menuOrderRepo = menuOrderRepo;
}

It's my first Project with Spring-Boot and I changed nothing in the configuration.

Answer 1

You need to make your boot application aware about your repository classes.

so add @EnableJpaRepositories("ch.post.pf.quick2lunch.repository") in your spring boot main class.
