How to split a file into lines in Camel, but process the first line differently

Question

I split the file into lines using a tokenizer:

.split().tokenize("\n", 1) 

However, some of the files I need to process will contain a header line, which should be handled differently with regular lines. Is there an easy way to read the first line, the process, and then split the remaining lines?

You can do something like this. He will use a content-based EIP router, and then various routines for processing.

 from(A) .split().tokenize("\n",1) .choice() .when(simple("${property.CamelSplitIndex} > 0")) .to("direct:processLine") .otherwise() .to("direct:processHeader"); from("direct:processLine") .bean(processLineBean) .to(B); from("direct:processHeader") .bean(processHeaderBean) .to(B);
