我正在开发一个Android应用程序,它与Spring中配置的jetty服务器交换数据.为了获得更动态的Android应用程序,我试图使用带有Stomp消息的WebSocket协议.

为了实现这个功能,我在Spring中配置了一个Web套接字消息代理:

@Configuration
//@EnableScheduling
@ComponentScan(
        basePackages="project.web",
        excludeFilters = @ComponentScan.Filter(type= FilterType.ANNOTATION, value = Configuration.class)
)
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/message");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/client");
    }
}

并SimpMessageSendingOperations在Spring控制器中从服务器向客户端发送消息:

@Controller
public class MessageAddController {
    private final Log log = LogFactory.getLog(MessageAddController.class);

    private SimpMessageSendingOperations messagingTemplate;

    private UserManager userManager;

    private MessageManager messageManager;

    @Autowired
    public MessageAddController(SimpMessageSendingOperations messagingTemplate, 
            UserManager userManager, MessageManager messageManager){
        this.messagingTemplate = messagingTemplate;
        this.userManager = userManager;
        this.messageManager = messageManager;
    } …
