Apache Camel Java DSL向正文添加换行符 [英] Apache Camel Java DSL add newline to body

问题描述

所以我在Java DSL中设置了一个netty4套接字路由，如下所示:

So I have a netty4 socket route set up in Java DSL that looks like the following:

@Override
public void configure() throws Exception {
    String dailyDataUri = "{{SOCKET.daily.file}}" + "&fileName=SocketData-${date:now:yyyyMMdd}.txt";
    from(socketLocation).routeId("thisRoute")
    .transform()
        .simple("${in.body}\n")
    .wireTap(dailyDataUri)
    .to(destination)
;

wireTap和目的地都将其数据发送到两个单独的文件.并且目标文件中的数据收集用\n(换行符)分隔开...或者至少应该分隔开.

Where both the wireTap and the destination are sending their data to two separate files. And the data collection in the destination file is separated by a \n (line break)... or at least it should be.

在查看创建的文件时，永远不会添加\n.

When viewing the files created, the \n is never added.

在我改用Java之前，Spring DSL中的等效想法已经起作用:

The equivalent idea in the Spring DSL worked before I switched to Java:

<transform>
    <simple>${in.body}\n</simple>
</transform>

使用该选项并打开在路由期间创建的文件后，通过套接字输入的数据行将由换行符分隔.

After using that and opening the files created during the route, the lines of data that came in through the socket would be separated by a newline.

我在Java DSL中做错了什么，不允许将换行符随输入的数据添加到套接字数据中?

我觉得这很明显，我只是看不到.

I feel like it's something obvious that I just don't see.

传入的数据只是一个类似CSV的文本行.

The data that is coming in is just a CSV-like line of text.

推荐答案

我找到了一个解决方案，我不确定从Spring到Java几乎可以将每个单词翻译成什么.显然，转换/简单组合存在一些问题，在Java DSL中它不适用于我.

I found a solution, I'm never sure what can be translated almost word from word from Spring to Java. Apparently the transform/simple combination has some issue where it will not work for me in Java DSL.

因此可能的解决方案(可能会有更多解决方案)是这样做的:

So a possible solution (there may be more solutions) is to do this:

@Override
public void configure() throws Exception {
    String dailyDataUri = "{{SOCKET.daily.file}}" + "&fileName=SocketData-${date:now:yyyyMMdd}.txt";
    from(socketLocation).routeId("thisRoute")
    .transform(body().append("\n"))
    .wireTap(dailyDataUri)
    .to(destination)
;

在这里，我没有调用简单语言来操纵主体，而是调用了主体，并在其后面附加了\n字符串.这就解决了我的问题.

Where instead of using the Simple language to manipulate the body, I just call on the body and append a String of \n to it. And that solves my issue.
