how to add delivery delay on AWS SQS messages using Spring JmsTemplate
问题
嗨，我想实现类似于使用Java和JmsTemplate发送具有特定传递延迟的SQS消息的函数。\n实际上，我已经完成了发送没有延迟的消息的实现。\n像这样：\n\n\n @Override\n public boolean sendMessage(String queueName, String message) throws EventBrokerException {\n final String messageWithTransactionGuid = addTransactionGuidToMessage(message);\n jmsTemplate.convertAndSend(queueName, messageWithTransactionGuid);\n return isSuccess;\n }\n\n\n我阅读了一些文章，也许我需要做类似这样的事情？\n\n\n jmsTemplate.convertAndSend(queueName, messageWithTransactionGuid, new MessagePostProcessor() {\n @Override\n public Message postProcessMessage(Message message) throws JMSException {\n message.setIntProperty(/*指定字段名和延迟秒数*/);\n return message;\n }\n });\n \n但我没有看到任何示例，我阅读了源代码，也没有找到需要指定什么，请问有人可以帮忙吗？

Hi I want to implement the function like sending sqs messages with a specific delivery delay using java and JmsTemplate.
Actually, I finished the implementation of sending messages without delay.
like this:
@Override
public boolean sendMessage(String queueName, String message) throws EventBrokerException {
final String messageWithTransactionGuid = addTransactionGuidToMessage(message);
jmsTemplate.convertAndSend(queueName, messageWithTransactionGuid);
return isSuccess;
}
I read some articles, Maybe I need to do somthing like this???
jmsTemplate.convertAndSend(queueName, messageWithTransactionGuid, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws JMSException {
message.setIntProperty(/*specify field name and delay seconds*/);
return message;
}
});
But I didn't see any examples, I read the sourcecode and didn't find out what to specify, can anybody help?

所以我所做的是一个简单的方法：
private Boolean doSendMessage(String queueName, String message, long deliveryDelay){
jmsTemplate.setDeliveryDelay(deliveryDelay);
jmsTemplate.convertAndSend(queueName, message);
jmsTemplate.setDeliveryDelay(DEFAULT_MESSAGE_DELIVERY_DELAY);
return isSuccess;
}
这里的 DEFAULT_MESSAGE_DELIVERY_DELAY 是 -1。
我注入了 jmsTemplate，并设置了 setDeliveryDelay 和 resetDeliveryDelay。

So what I did is a simple way:
private Boolean doSendMessage(String queueName, String message, long deliveryDelay){
jmsTemplate.setDeliveryDelay(deliveryDelay);
jmsTemplate.convertAndSend(queueName, message);
jmsTemplate.setDeliveryDelay(DEFAULT_MESSAGE_DELIVERY_DELAY);
return isSuccess;
}
Here DEFAULT_MESSAGE_DELIVERY_DELAY is -1.
I injected jsmTemplate, and setDeliveryDelay and resetDeliveryDelay
