THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

For further examples of this pattern in use you could look at one of the junit test case
Stop processing in case of exception
Available as of Camel 2.1
The Multicast will by default continue to process the entire Exchange even in case one of the multicasted messages will thrown an exception during routing.
For example if you want to multicast to 3 destinations and the 2nd destination fails by an exception. What Camel does by default is to process the remainder destinations. You have the chance to remedy or handle this in the AggregationStrategy.
But sometimes you just want Camel to stop and let the exception be propagated back, and let the Camel error handler handle it. You can do this in Camel 2.1 by specifying that it should stop in case of an exception occurred. This is done by the stopOnException option as shown below:
| Code Block |
|---|
from("direct:start")
.multicast()
.stopOnException().to("direct:foo", "direct:bar", "direct:baz")
.end()
.to("mock:result");
from("direct:foo").to("mock:foo");
from("direct:bar").process(new MyProcessor()).to("mock:bar");
from("direct:baz").to("mock:baz");
|
And using XML DSL you specify it as follows:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<route>
<from uri="direct:start"/>
<multicast stopOnException="true">
<to uri="direct:foo"/>
<to uri="direct:bar"/>
<to uri="direct:baz"/>
</multicast>
<to uri="mock:result"/>
</route>
<route>
<from uri="direct:foo"/>
<to uri="mock:foo"/>
</route>
<route>
<from uri="direct:bar"/>
<process ref="myProcessor"/>
<to uri="mock:bar"/>
</route>
<route>
<from uri="direct:baz"/>
<to uri="mock:baz"/>
</route>
