Can't Spring Data simply push my code onto the remote cluster and trigger the execution? 来源：

问题 In this great answer https://stackoverflow.com/a/27161986/4358405 there is an example of how to use raw Spring4 WebSockets without STOMP subprotocol (and without SockJS potentially). Now my question is: how do I broadcast to all clients? I expected to see an API that I could use in similar fashion with that of pure JSR 356 websockets API: session.getBasicRemote().sendText(messJson); Do I need to keep all WebSocketSession objects on my own and then call sendMessage() on each of them? 回答1: I

问题 With Spring 4 and Hibernate 4, I was able to use Reflection to get the Hibernate Configuration object from the current environment, using this code: @Autowired LocalContainerEntityManagerFactoryBean lcemfb; EntityManagerFactoryImpl emf = (EntityManagerFactoryImpl) lcemfb.getNativeEntityManagerFactory(); SessionFactoryImpl sf = emf.getSessionFactory(); SessionFactoryServiceRegistryImpl serviceRegistry = (SessionFactoryServiceRegistryImpl) sf.getServiceRegistry(); Configuration cfg = null; try
