Method Detail

bean

public static <T> ServiceFactory<?,T> bean(@Nonnull
                                           String beanName,
                                           @Nonnull
                                           Class<T> requiredType)

Returns a Spring Bean ServiceFactory. The factory creates a context object which autowires the ApplicationContext. The context object obtains the specified bean from ApplicationContext and returns it as a service.

Below is a sample usage which reads the names from a list and maps those names to User objects using the spring bean userDao.

 Pipeline pipeline = Pipeline.create();
 pipeline.<String>readFrom(Sources.list(LIST_NAME))
         .mapUsingService(JetSpringServiceFactories.bean("userDao", UserDao.class),
                 (userDao, item) -> userDao.findByName(item.toLowerCase(Locale.ROOT)))
         .writeTo(Sinks.logger());
 

Type Parameters:

T - the type of the bean

Parameters:

beanName - the name of the bean

requiredType - the class of the bean
