Spring rabbit converter3/17/2023 You need to set the content_type="text/plain" and convert the JSON to a string.Then in the Spring side, use a fuction with a string as the input as the listener and manually convert the object. Solution 1: Sending as JSON string and convert it manually using Jakson or GSON Let me describe with an example where I had a Python Producer and Java consumer (I was sending the JSON from Python to RabbitMQ and Spring Boot Java was supposed to receive the JSON task). In order to send JSON to RabbitMQ and consume it by Spring Boot we need to set content_type. If anyone has a good explanation, please share it in the comments section. I still don't fully understand why it is not working at the class level. Your receiver code should look like this after editing. So, I remove and move to the receive method. A new property recoverManualDeclarations allows recovery of manually declared. When I instead call a service activator on this channel, the message is not being converted. See Converting from a Message for more information. When you move it to the method level, though, it works fine.

Trying out the spring-integration-amqp from the sandbox and as a very simple example, sending a text message to the rabbit queue, receiving it on a channel and sending it on the standard out, works fine and the string message gets printed out. support.ListenerExecutionFailedException: Failed to convert messageĪt .(MessagingMessageListenerAdapter.java:146) ~Īt .(AbstractMessageListenerContainer.java:1654) ~Īt .(AbstractMessageListenerContainer.java:1573) ~Īt .(AbstractMessageListenerContainer.java:1561) ~Īt .(AbstractMessageListenerContainer.java:1552) ~Īt .(AbstractMessageListenerContainer.java:1496) ~Īt .(SimpleMessageListenerContainer.java:968) Īt .(SimpleMessageListenerContainer.java:914) Īt .$1600(SimpleMessageListenerContainer.java:83) Īt .listener.SimpleMessageListenerContainer$AsyncMessageProcessingConsumer.mainLoop(SimpleMessageListenerContainer.java:1289) Īt .listener.SimpleMessageListenerContainer$n(SimpleMessageListenerContainer.java:1195) Īt (Thread.java:748) Ĭaused by: : No method found for class Īt .(DelegatingInvocableHandler.java:185) ~Īt .(DelegatingInvocableHandler.java:317) ~Īt .(HandlerAdapter.java:110) ~Īt .(MessagingMessageListenerAdapter.java:192) ~Īt .(MessagingMessageListenerAdapter.java:137) ~Īfter hours of searching through different websites without any good answer, I finally found out that won't work at the class level. It simply returns an error message like this. When I set up a receiver like yours, I experienced the similar problem where I couldn't convert JSON in the body of the RabbitMQ Message to my object. Just in case someone else is having the same issues. The exception says there is no converter, and that is true, my problem is that I have no idea how to set the MappingJackson2MessageConverter converter in the consumer side (please note that I want to use .MappingJackson2MessageConverter and not .converter.I know its been awhile since the last response, but I'd want to add my answer.

The "consumer" should receive and convert the json message into a domain Foo and Bar respectively.įor some reason I can not make this simple task. The rainiest season is Summer when it rains 31 of the time and the driest is Spring with only a 19 chance of a rainy day. Used to resolve Object parameters to convertAndSend methods and Object results from receiveAndConvert methods. The Foo Spring Controller is hit, and returns the corresponding Foo Java entities. Let’s clarify this with a quick example: The Client sends a GET request to /foos, with the Accept header set to application/json, to get all Foo resources as JSON. Foo and Bar which should be converted to json and send to rabbitmq. spring: rabbitmq: listener: simple: retry: enabled: true initial-interval: 3s max-attempts: 6 max-interval: 10s multiplier: 2 server: port: 8081 The model class Student can be defined as follows- JsonIdentityInfo helps in serialising the instance of an object having the id of the object. Set the message converter for this template. Then itll search for a HttpMessageConverter that can convert the body sent by the client to a Java Object. So I have two apps (or microservices if you wish). I'm trying to create a simple spring boot app with spring boot that "produce" messages to a rabbitmq exchange/queue and another sample spring boot app that "consume" these messages.
