Question

使用Camel 2.8.0
使用Jetty 7.5.4

from("jetty://http://myESBserver/large/resource?matchOnUriPrefix=true&bridgeEndpoint=true&enableMultipartFilter=false&disableStreamCache=true&continuationTimeout=1440000")  
.to("jetty://http://myWEBserver/large/resource?bridgeEndpoint=true&throwExceptionOnFailure=false");

此路线适用于较小的资源。我要求Camel代理请求而不进行修改（在交换完成后进行日志记录）。我试图代理的文件相当大（约7G）。

代码在内部使用ByteArrayOutputStream，其最大大小限制为Integer.MAX_VALUE - 约2GB。

在此之前还有另一个错误，即long会以某种方式被降级为整数，但ByteArrayOutputStream似乎是根本问题。

因此，您似乎必须将数据拆分为单独的块或使用不同的方法。
