    • getTypePrecedence

      public JacksonJavaTypeMapper.TypePrecedence getTypePrecedence()
      Return the precedence.
      Specified by:
      getTypePrecedence in interface JacksonJavaTypeMapper
      Returns:
      the precedence.
      See Also:

    • setTypePrecedence

      public void setTypePrecedence(JacksonJavaTypeMapper.TypePrecedence typePrecedence)
      Set the precedence for evaluating type information in message properties. When using @RabbitListener at the method level, the framework attempts to determine the target type for payload conversion from the method signature. If so, this type is provided in the inferredArgumentType message property.

      By default, if the type is concrete (not abstract, not an interface), this will be used ahead of type information provided in the __TypeId__ and associated headers provided by the sender.

      If you wish to force the use of the __TypeId__ and associated headers (such as when the actual type is a subclass of the method argument type), set the precedence to JacksonJavaTypeMapper.TypePrecedence.TYPE_ID.

      Parameters:
      typePrecedence - the precedence.
