2.19.0 Rest Producer DSL http4 support for PUT workaround
I have swapped out a route previously using http4 directly for the more
succinct newly released producer DSL.
What was working as:
from("direct:getCounter")
.routeId("i4ip-Get-Counter")
.setHeader("CamelHttpMethod", constant("PUT"))
.to("http4://{{counter.service.host}}:{{counter.service.port}}/api/counter/{{counter.name}}")
.unmarshal().json(JsonLibrary.Jackson,CounterPojo.class)
.setBody().simple("${body.getCounter()}")
.convertBodyTo(Integer.class)
.log(LoggingLevel.INFO, "returned ${body} for counter:
{{counter.name}}")
;
I changed to:
restConfiguration().host("{{counter.service.host}}").port("{{counter.service.port}}");
from("direct:getCounter")
.routeId("i4ip-Get-Counter")
*.setHeader("CamelHttpMethod", constant(HttpMethods.PUT))*
.to("rest:*put*:api/counter/{{counter.name}}")
.unmarshal().json(JsonLibrary.Jackson,CounterPojo.class)
.setBody().simple("${body.getCounter()}")
.convertBodyTo(Integer.class)
.log(LoggingLevel.INFO, "returned ${body} for counter:
{{counter.name}}")
;
}
I was getting a 404 because the PUT request was being transformed to a POST
since http4/HttpMethodHelper
<https://github.com/apache/camel/blob/master/components/camel-http4/src/main/java/org/apache/camel/component/http4/helper/HttpMethodHelper.java>
turns a request to POST if there is a payload. My PUT has a payload but it
the method in the URI is ignored. However you can manually set the header
as above and it works fine.
Not sure whether this is for non http4 libraries. The example in the camel
source code for the DSL producer is just a GET.

Hi
Ah yeah the put in the rest url should take precedence. Can you log a
JIRA ticket.
