Spring WebSocket ConvertAndSendToUser 不工作但 convertAndSend 工作 [英] Spring WebSocket ConvertAndSendToUser not working but convertAndSend working

问题描述

我是 Spring Boot websocket 和消息传递语义的新手.目前我可以使用以下代码发送私人消息.

I am new to Spring boot websocket and messaging semantics. Currently i am able to send private messages using the below code.

String queueName = "/user/" + username  + "/queue/wishes";
simpMessagingTemplate.convertAndSend(queueName, message);

尝试使用 convertAndSendToUser 时，我没有收到任何错误，但没有发送消息.我知道使用 sendToUser 应该对目的地名称的形成方式略有变化，但我没有做对.

When trying to use convertAndSendToUser I am not getting any error but the message is not getting sent. I knew that with sendToUser there should be a slight change in how the destination name should be formed but I am not getting it right.

String queueName = "/user/queue/wishes";
        simpMessagingTemplate.convertAndSendToUser(username, queueName, message);

下面是我的订阅代码.

 stompClient.subscribe('/user/queue/wishes', function(message) {
            alert(message);
        }) 

推荐答案

终于解决了问题.我犯了一个愚蠢的错误.我正在填充 User DestinationPrefix 作为 WebSocket 配置的一部分.但没有为注入的 bean SimpMessaging 模板设置它.

Finally figured out the problem. I did a silly mistake. I was filling the User DestinationPrefix as part of WebSocket config. but didn't set it up for the injected bean SimpMessaging template.
