Question

我正尝试使用Apache Camel向Azure Queue发送消息，路由代码为：

from("direct:testMessage")
    .process(exchange -> {
        exchange.getIn().setBody("test message");
    })
    .to("azure-storage-queue://azureaccount/test-queue?operation=sendMessage");

启动Azure服务客户端bean的代码是：

@Bean
public QueueServiceClient queueServiceClient() {
    StorageSharedKeyCredential credential = new StorageSharedKeyCredential(ACCOUNT, ACCESS_KEY);
    return new QueueServiceClientBuilder().endpoint(QUEUE_URL).credential(credential).buildClient();
}

我收到以下错误：

com.azure.storage.queue.models.QueueStorageException: Status code 400, "<?xml version="1.0" encoding="utf-8"?><Error><Code>InvalidXmlDocument</Code><Message>XML specified is not syntactically valid.
RequestId:e3496af3-f003-001a-0d2e-a38636000000
Time:2020-10-15T20:08:26.5431469Z</Message><LineNumber>0</LineNumber><LinePosition>0</LinePosition><Reason /></Error>"

尝试启用HTTP日志，并且消息正文为空：

2020-10-16 01:38:25 INFO  c.a.s.q.i.M.enqueue - --> POST https://azureaccount.queue.core.windows.net/blob-backup-queue/messages
53-byte body:
<?xml version='1.0' encoding='UTF-8'?><QueueMessage/>
--> END POST

2020-10-16 01:38:25 INFO  c.a.s.q.i.M.enqueue - <-- 400 https://azureaccount.queue.core.windows.net/blob-backup-queue/messages (163 ms, 294-byte body)
Response body:

浏览骆驼天蓝色组件的源代码，找出正确的消息发送方式如下：

exchange.getIn().getHeaders().put(QueueConstants.MESSAGE_TEXT, "test message");
