Inline Simple expressions
Available as of Camel 2.18
Its now possible to inlined Simple language expressions in the JSonPath expression using the simple syntax ${xxx}. An example is shown below:
| Code Block |
|---|
from("direct:start")
.choice()
.when().jsonpath("$.store.book[?(@.price < ${header.cheap})]")
.to("mock:cheap")
.when().jsonpath("$.store.book[?(@.price < ${header.average})]")
.to("mock:average")
.otherwise()
.to("mock:expensive"); |
In this example the Simple expression inlined is the headers with the cheap and average values to be used.
| Code Block | ||||
|---|---|---|---|---|
| ||||
<route>
<from uri="direct:start"/>
<choice>
<when>
<jsonpath>$.store.book[?(@.price < ${header.cheap})]</jsonpath>
<to uri="mock:cheap"/>
</when>
<when>
<jsonpath>$.store.book[?(@.price < ${header.average})]</jsonpath>
<to uri="mock:average"/>
</when>
<otherwise>
<to uri="mock:expensive"/>
</otherwise>
</choice>
</route> |
JSonPath injection
You can use Bean Integration to invoke a method on a bean and use various languages such as JSonPath to extract a value from the message and bind it to a method parameter.
