为什么我的 Camel Netty 路由在 JMS 消息的开头添加换行符?

问题描述

我有一个 Camel Netty 路由，它将 XML 发送到服务器端口并将其放入 JMS 消息中.在第一条消息之后，其他每条消息的顶部都有一个换行符，导致我的 XML 在 GUI 接收到它时无法解组.

I have a Camel Netty route that takes XML sent to a server port and places it in a JMS message. After the first message, every other message has a newline at the top of the message, causing my XML to fail to unmarshall when a GUI receives it.

我的路线是这样的:

<route>
        <from uri="netty4:tcp://localhost:5150?decoders=#customFrameDelimeterDecoder,#string-decoder&amp;encoder=#string-encoder"/>
         <to uri="jms:topic:my.company.topic"/>

</route>

注意:XML 不是换行符终止的，因此需要自定义帧分隔符解码器.

Note: The XML is not newline terminated, hence the need for a custom frame delimeter decoder.

推荐答案

试试设置:

    <from uri="netty4:tcp://localhost:5150?textline=true&delimiter=NULL"/>

问题是 camel-netty4 是 由于编解码器文本向您的消息添加分隔符，所以它似乎放置了一个空字符串在您的消息末尾.

The problem is that camel-netty4 is adding a delimiter to your message because of the codec text, so it seems that it is putting a empty string at the end of your message.

您也可以尝试将 autoAppendDelimiter 添加为 false.根据文档:

You could also try to add autoAppendDelimiter to false. According to docs:

分隔符 |线 |用于文本行编解码器的分隔符.可能的值为 LINE 和 NULL

autoAppendDelimiter |真实 |使用 textline 编解码器发送时是否自动附加缺少的结束分隔符.

autoAppendDelimiter | true | Whether or not to auto append missing end delimiter when sending using the textline codec.

干杯！
