需要拦截@SqsListener

Question

我必须从Sqs消息中检索标头，但是我无法更改当前代码，因此标头自动装配不是一个选择。

# Test data for rankedchoice.cpp
# Expected output: 4
8
1 4 3 2
2 4 3 1
2 1 4 3
3 1 2 4
3 2 1 4
3 1 4 2
4 2 3 1
4 1 3 4

# Expected output: 4

4 1 3 4
4 2 3 1
3 2 1 4
3 1 2 4
2 4 3 1
2 1 4 3
1 4 3 2
3 1 4 2

# Expected output: 1

# Expected output: 1 3

# Expected output: 1
# Because there are no first-place votes for 4, it should be eliminated,
# and the 3 4 1 2 ballots should put 1 over the top on the second ballot.

我尝试用@SqsListener(value = "...") public void processMessage(Message event) { processor.process(event); } 来做。我可以使用QueueMessagingTemplate和QueueMessageChannel为其分配拦截器，但是我不能告诉sqs使用该模板接收消息。

感谢帮助。
