如何使用ExecutorSubscribableChannel [英] How to use ExecutorSubscribableChannel

问题描述

与​​ autowire simpmessagingtemplate 相关的问题

我遇到类ExecutorSubscribableChannel的问题。我希望服务器向浏览器发送异步消息。 如何正确使用ExecutorSubscribableChannel ？

I am having problem the class ExecutorSubscribableChannel. I want the server to send a asynchronous message to the browser. How can I use properly ExecutorSubscribableChannel ?

示例：

public class GreetingController {


    @Autowired
    private SimpMessagingTemplate template;

    public void setTemplate(SimpMessagingTemplate template) {
        this.template = template;
    }

    @MessageMapping("/hello")
    @SendTo("/topic/greetings")
    public Greeting greeting(HelloMessage message) throws Exception {
        Thread.sleep(5000); // simulated delay
        this.template.convertAndSend("/topic/greetings", "Hello World");
        return new Greeting("Hello, " + message.getName() + "!");
    }
}

但是我发送的你好世界文字在行

but the "hello world" text that I am sending in the line

this.template.convertAndSend("/topic/greetings", "Hello World");

。其他一切正常。

bean的配置是：

<bean id="executorSC" class="org.springframework.messaging.support.ExecutorSubscribableChannel"/>

<bean id="template" class="org.springframework.messaging.simp.SimpMessagingTemplate">
    <constructor-arg index="0" ref="executorSC"/>
</bean>

提前致谢。
