为什么我的Camel Netty路由在我的JMS消息的开头添加换行符? [英] Why is my Camel Netty route adding newlines to the start of my JMS messages?

问题描述

我有一个Camel Netty路由，该路由将XML发送到服务器端口，并将其放置在JMS消息中.在第一条消息之后，每条其他消息在消息顶部都有一个换行符，导致GUI收到XML时无法取消编组.

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.

我的路线如下:

<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不是以换行符结尾的，因此需要自定义帧分界符解码器.

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

推荐答案

尝试设置:

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

问题是camel-netty4是

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.

您还可以尝试将autoAppendDelimiter添加到false. 根据文档:

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

定界符 | LINE |用于文本行编解码器的定界符.可能的值为LINE和NULL

delimiter | LINE | The delimiter to use for the textline codec. Possible values are LINE and NULL

autoAppendDelimiter |真实|使用文本行编解码器发送时是否自动追加缺少的结尾定界符.

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

干杯！
