Michael Weiss updated CAMEL-24173:
----------------------------------
Description:
I usually use `autoDeclare: true` when connecting to RabbitMQ. Example:
{code:yaml}
- route: id: route-8723
from: id: from-3034
uri: spring-rabbitmq
parameters: autoDeclare: true
deadLetterExchange: CamelPlayground.RabbitMqDemo.deadletter
deadLetterQueue: CamelPlayground.RabbitMqDemo.OffRamp.deadletter
deadLetterRoutingKey: OffRamp
exchangeName: CamelPlayground.RabbitMqDemo
queues: CamelPlayground.RabbitMqDemo.OffRamp
routingKey: OffRamp
steps: - log: id: log-3784
message: ${body}
{code}
It seems Camel uses a deprecated feature called
`{{{}transient_nonexcl_queues{}}}` which is disabled by default in rabbitmq
server 4.3.0+. According to AI this is because Camel by default sets
{{arg.queue.durable=false}} which does not seem to be possible due to this
removed feature anymore. Shouldn't we set {{arg.queue.durable=true}} by default?

AI analysis of the issue:
{*}Starting from RabbitMQ 4.3.0{*}, the {{transient_nonexcl_queues}} deprecated
feature was moved from {{permitted_by_default}} to {*}{{denied_by_default}}{*}.
The queue your Camel consumer is trying to declare is:
{noformat}
Queue(CamelPlayground.RabbitMqDemo.OffRamp) durable:false, auto-delete:false,
exclusive:false{noformat}
This is a *non-durable (transient), non-exclusive* queue — the exact
combination that RabbitMQ 4.3+ rejects by default.
h3. Solution 1 (Recommended — Client-side fix): Make the queue durable
Change your Camel route to declare the queue as {*}durable{*}. In the
{{camel-spring-rabbitmq}} component, you can do this via the *{{queues}}*
parameter combined with the *{{args}}* parameter, or by configuring the
{{Queue}} bean properly.
was:
I usually use `autoDeclare: true` when connecting to RabbitMQ. Example:
{code:yaml}
- route: id: route-8723
from: id: from-3034
uri: spring-rabbitmq
parameters: autoDeclare: true
deadLetterExchange: CamelPlayground.RabbitMqDemo.deadletter
deadLetterQueue: CamelPlayground.RabbitMqDemo.OffRamp.deadletter
deadLetterRoutingKey: OffRamp
exchangeName: CamelPlayground.RabbitMqDemo
queues: CamelPlayground.RabbitMqDemo.OffRamp
routingKey: OffRamp
steps: - log: id: log-3784
message: ${body}
{code}
It seems Camel uses a deprecated feature called
`{{{}transient_nonexcl_queues{}}}` which was removed from rabbitmq server in
4.3.0. According to AI this is because Camel by default sets
{{arg.queue.durable=false}} which does not seem to be possible due to this
removed feature anymore. Shouldn't we set {{arg.queue.durable=true}} by default?

{noformat}
AI analysis of the issue:
{*}Starting from RabbitMQ 4.3.0{*}, the {{transient_nonexcl_queues}} deprecated
feature was moved from {{permitted_by_default}} to {*}{{denied_by_default}}{*}.
The queue your Camel consumer is trying to declare is:
{noformat}
Queue(CamelPlayground.RabbitMqDemo.OffRamp) durable:false, auto-delete:false,
exclusive:false{noformat}
This is a *non-durable (transient), non-exclusive* queue — the exact
combination that RabbitMQ 4.3+ rejects by default.
h3. Solution 1 (Recommended — Client-side fix): Make the queue durable
Change your Camel route to declare the queue as {*}durable{*}. In the
{{camel-spring-rabbitmq}} component, you can do this via the *{{queues}}*
parameter combined with the *{{args}}* parameter, or by configuring the
{{Queue}} bean properly.

> It seems Camel uses a deprecated feature called
> `{{{}transient_nonexcl_queues{}}}` which is disabled by default in rabbitmq
> server 4.3.0+. According to AI this is because Camel by default sets

> AI analysis of the issue:
> {*}Starting from RabbitMQ 4.3.0{*}, the {{transient_nonexcl_queues}}
> deprecated feature was moved from {{permitted_by_default}} to
> {*}{{denied_by_default}}{*}. The queue your Camel consumer is trying to
> declare is:
> {noformat}
> Queue(CamelPlayground.RabbitMqDemo.OffRamp) durable:false, auto-delete:false,
> exclusive:false{noformat}
> This is a *non-durable (transient), non-exclusive* queue — the exact
> combination that RabbitMQ 4.3+ rejects by default.
> h3. Solution 1 (Recommended — Client-side fix): Make the queue durable
> Change your Camel route to declare the queue as {*}durable{*}. In the
> {{camel-spring-rabbitmq}} component, you can do this via the *{{queues}}*
> parameter combined with the *{{args}}* parameter, or by configuring the
> {{Queue}} bean properly.
