[在我的应用程序中，正在使用apache骆驼处理txt文件，应用程序使用交换对象将整个文件读入字符串，并在每行上添加分隔符，并使用apache骆驼的交换对象将其作为整个字符串写入文件。我低于OutOfMemoryError。 ***我观察到此异常是在交换对象完成文件处理后发生的，并且应该将文件移动到另一个文件夹（端点）* **。
我的应用程序具有16GB的堆空间支持。处理前的文件大小为685MB，添加分隔符后可能会增加200 MB。有人能帮我一下吗？预先谢谢你。
from("file:<filepath>/processed/INPUT?filter=#fileFilter&delay=120000&exclusiveReadLockStrategy=#fileReadLockStrategy&delete=true&autoCreate=true")
.threads(10, 10)
.process(fileProcessor).log("Came out of file processor")
.recipientList(header(DESTIONATION_PATH));
这是一条简单的路线，它从INPUT文件夹中读取文件，而fileProcessor通过在其中添加delimter来处理文件内容。 DESTIONATION_PATH是将放置文件的路径。我可以看到它正在打印日志“文件处理器超出限制”，下面是当文件即将发送到目标文件夹时出现异常。

很抱歉在这里迟到了。我能够解决上述问题。当我仔细查看日志时，它在标准Java类“ StringCoding.java”中失败。
我的代码中的罪魁祸首是以下两行：
String content = exchange.getIn().getBody(String.class);
//Add deleimters in each line content string & write back the whole string in file.
//derive new content string from original content
exchange.getOut().setBody(content);// Camel stores content in String & sends it via route using character array.
Analysis：] >>
Java将字符串作为字符数组存储在后台。根据逻辑，我们在每行中添加了一些距离。我观察到（原始文件中的字符数+添加的分隔符数）> Integer.MAX_VALUE。因此，这里的Java无法将整个字符串存储到字符数组中，并且骆驼无法将文件放入在目标文件夹路径中。发生这种情况是因为修改后的文件中的字符数超出了最大整数大小。
解决方案：
]File contentFile = exchange.getIn().getBody(File.class); //Process the contentFile as file line by line & write the records back in file. exchange.getOut().setBody(contentFile);// Camel stores content in File & sends it via route using InputStream.我保留了上面的代码，并且它起作用了，我们没有看到OutofMemory问题，因为在通过路由发送文件时骆驼在哪里使用数组。
谢谢您的阅读。快乐编码... !!!
