Problem

Suppose you have two classes that should be registered with Spring context exclusively, e.g. only one of the beans must exist in the context at any time based on some boolean property value. Of course you can do it by adding explicit if condition into your @Configuration class. But if the classes have no common interface it may be quite cumbersome. As an alternative you can use @ConditionalOnProperty annotation on your classes, e.g.:

@Service
@ConditionalOnProperty(name = "use-left-service", havingValue = "true", matchIfMissing = false)
public class LeftService

Connecting to serial port (com port) over network

(Serial port or com port? - Serial ports are often refered as COM ports. It is the same to be short. You can read abut it in the Wiki article )
