Java WebSocket convertAndSendToUser无法接收消息

我正在使用websocket向客户端发送消息，当使用此方法向客户端广播消息时

private void pushInfoImpl(String url, String content) {
    if (simpMessagingTemplate != null) {
        simpMessagingTemplate.convertAndSend(url, content);
    }
}

客户端无法成功接收消息。使用此方法发送指定用户时：

//send url:/queue/location
//user:admin
 private void pushInfoImpl(String user, String url, String content) {
    if (simpMessagingTemplate != null) {
        simpMessagingTemplate.convertAndSendToUser(user, url, content);
    }
}

客户端无法接收发送的消息。我所尝试的：

在config.enableSimpleBroker（“/topic”，“/queue”）中添加队列

订阅url，如

stompClient.subscribe（'/admin/queue/location'，function（greeting）{console.log（greeting.body）；}）.admin是用户

我应该如何解决此问题？使客户端成功接收服务器消息。这是日志：

原因是url不正确，在服务器上，发送参数应如下所示：

user: admin
url: /location(right) vs /queue/location(wrong)

/user/admin/location or /user/{username}/location

在客户机上，子订阅应如下所示：

user: admin
url: /location(right) vs /queue/location(wrong)

/user/admin/location or /user/{username}/location
