Header
Since Camel 1.5
The Header Expression Language allows you to extract values of named headers.
Header Options
The Header language supports 1 options, which are listed below.
| Name | Default | Java Type | Description |
|---|---|---|---|
trim |
|
|
Whether to trim the value to remove leading and trailing whitespaces and line breaks |
Example usage
The recipientList element of the Spring DSL can utilize a header expression like:
In this case, the list of recipients are contained in the header 'myHeader'.
And the same example in Java DSL:
And with a slightly different syntax where you use the builder to the fullest (i.e. avoid using parameters but using stacked operations, notice that header is not a parameter but a stacked method call)
from("direct:a").recipientList().header("myHeader");
