Create Bean java.lang.ClassNotFoundException #1063

Closed rapetum228 closed 9 months ago

rapetum228 commented 9 months ago

I want to use integration using Camel Karavan. The essence of integration is to receive messages from REST service and transfer them to RabbitMq. To create a connection to RabbitMq I made Bean.

Here is my yaml file:

- rest:
    id: rest-6f81
    post:
      - id: post-78d2
        path: /test
        to: direct:internal
        consumes: application/json
- beans:
    - constructors: {}
      name: RabbitMQConnectionFactory
      properties:
        host: 'localhost'
        port: '5672'
        username: Test
        password: Test
      type: org.springframework.amqp.rabbit.connection.CachingConnectionFactory
- route:
    id: route-d7a0
    nodePrefixId: route-425
    from:
      id: from-b82a
      uri: direct
      parameters:
        name: internal
      steps:
        - log:
            id: log-90a7
            message: ${body}
        - to:
            id: to-bcd8
            uri: spring-rabbitmq
            parameters:
              exchangeName: test
              testConnectionOnStartup: true
              connectionFactory: '#bean:RabbitMQConnectionFactory'

At startup.

I get the following error logs:

I think the key problem is this: java.lang.ClassNotFoundException: org.springframework.amqp.rabbit.connection.ConnectionFactory But org.springframework.amqp.rabbit.connection.ConnectionFactory is existed in Spring RabbitMQ.

Can anyone tell me how to fix this? I'm new to Camel and really don't understand what might be missing. Maybe I'm missing something small.

I use camel-karavan as VS Code extension. Same error when running through docker.

UPD. Added file application.properties

Try adding camel-spring-rabbitmq dependency for camel.jbang.dependencies in application.properties and see if it will help.
