      Parameters:
      explicitDeclarationsOnly - true to ignore beans with no admin declaration configuration.
      Since:
      2.1.9

    • isRedeclareManualDeclarations

      public boolean isRedeclareManualDeclarations()
      Normally, when a connection is recovered, the admin only recovers auto-delete queues, etc, that are declared as beans in the application context. When this is true, it will also redeclare any manually declared Declarables via admin methods.
      Returns:
      true to redeclare.
      Since:
      2.4

    • setRedeclareManualDeclarations

      public void setRedeclareManualDeclarations(boolean redeclareManualDeclarations)
      Normally, when a connection is recovered, the admin only recovers auto-delete queues, etc., that are declared as beans in the application context. When this is true, it will also redeclare any manually declared Declarables via admin methods. When a queue or exchange is deleted, it will no longer be recovered, nor will any corresponding bindings.
      Parameters:
      redeclareManualDeclarations - true to redeclare.
      Since:
      2.4
      See Also:

    • setRetryTemplate

      public void setRetryTemplate(@Nullable org.springframework.retry.support.RetryTemplate retryTemplate)
      Set a retry template for auto declarations. There is a race condition with auto-delete, exclusive queues in that the queue might still exist for a short time, preventing the redeclaration. The default retry configuration will try 5 times with an exponential backOff starting at 1 second a multiplier of 2.0 and a max interval of 5 seconds. To disable retry, set the argument to null. Note that this retry is at the macro level - all declarations will be retried within the scope of this template. If you supplied a RabbitTemplate that is configured with a RetryTemplate, its template will retry each individual declaration.
      Parameters:
      retryTemplate - the retry template.
      Since:
      1.7.8

    • setBeanName

      public void setBeanName(String name)
      Specified by:
      setBeanName in interface BeanNameAware

    • getBeanName

      public String getBeanName()

    • isAutoStartup

      public boolean isAutoStartup()

    • afterPropertiesSet

      public void afterPropertiesSet()
      If autoStartup is set to true, registers a callback on the ConnectionFactory to declare all exchanges and queues in the enclosing application context. If the callback fails then it may cause other clients of the connection factory to fail, but since only exchanges, queues and bindings are declared failure is not expected.
      Specified by:
      afterPropertiesSet in interface InitializingBean
      See Also:

    • initialize

      public void initialize()
      Declares all the exchanges, queues and bindings in the enclosing application context, if any. It should be safe (but unnecessary) to call this method more than once.
      Specified by:
      initialize in interface AmqpAdmin

    • resetAllManualDeclarations

      public void resetAllManualDeclarations()
      Invoke this method to prevent the admin from recovering any declarations made by calls to declare*() methods.
      Since:
      2.4

      Return the manually declared AMQP objects.
      Specified by:
      getManualDeclarableSet in interface AmqpAdmin
