THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
Camel allows OGNL to be used as an Expression or Predicate the DSL or Xml Configuration.
For example you could use OGNL inside a Message Filter in XML
| Code Block |
|---|
<route>
<from uri="seda:foo"/>
<filter>
<ognl>request.headers.foo = 'bar'</ognl>
<to uri="seda:bar"/>
</filter>
</route>
|
You could use OGNL to create an Predicate in a Message Filter or as an Expression for a Recipient List
...
Variable | Type | Description |
|---|---|---|
this | Exchange | the Exchange is the root object |
exchange | Exchange | the Exchange object |
exception | Throwable | the Exchange exception (if any) |
exchangeId | String | the exchange Id |
fault | Message | the Fault message (if any) |
request | Message | the exchange.in message |
response | Message | the exchange.out message (if any) |
properties | Map | the exchange properties |
property(name) | Object | the property by the given name |
property(name, type) | Type | the property by the given name as the given type |
Samples
For example you could use OGNL inside a Message Filter in XML
| Code Block |
|---|
<route>
<from uri="seda:foo"/>
<filter>
<ognl>request.headers.foo = 'bar'</ognl>
<to uri="seda:bar"/>
</filter>
</route>
|
And the sample using Java DSL:
| Code Block | ||||
|---|---|---|---|---|
| ||||
from("seda:foo").filter().ognl("request.headers.foo = 'bar'").to("seda:bar");
|
Dependencies
To use OGNL in your camel routes you need to add the a dependency on camel-ognl which implements the OGNL language.
