spring-boot 1.2.0.M2 breaks app

I have a spring boot app that worked fine up until I updated from 1.2.0.M1 to 1.2.0.M2. The app will not build because of an UnsatisfiedDependencyException resulting from spring-boot RabbitAutoConfiguration:

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException:
    Error creating bean with name 'jmsMessagingTemplate' defined in class path resource [org/springframework/boot/autoconfigure/amqp/RabbitAutoConfiguration$MessagingTemplateConfiguration.class]: 
    Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.amqp.rabbit.core.RabbitTemplate]: :
    No qualifying bean of type [org.springframework.amqp.rabbit.core.RabbitTemplate] is defined: 
    expected single matching bean but found 3: looperTemplate,pingTemplate,orgRequestTemplate; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: 
    No qualifying bean of type [org.springframework.amqp.rabbit.core.RabbitTemplate] is defined: 
    expected single matching bean but found 3: looperTemplate,pingTemplate,orgRequestTemplate
at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:751) ~[spring-beans-4.1.1.RELEASE.jar:4.1.1.RELEASE]
at org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:466) ~[spring-beans-4.1.1.RELEASE.jar:4.1.1.RELEASE]

The problem is I do have RabbitMQ templates, but I have 3 of them and it needs a qualifier to select a single template. However this code is in spring-boot, not my code. I would prefer not to have to alter spring-boot code, but I am not sure what I should do in my code to prevent this exception.

I can see the offending jmsMessagingTemplate was added in the 1.2.0.M2 version. The naming of this is also misleading as I do not have JMS enabled in my app (although this is a RabbitMQ specific auto configuration file in spring-boot).

Any suggestions on how I can configure my code without eliminating templates or modifying spring-boot code?

I've created #1701 to track the naming issue. You should read rabbitMessagingTemplate there.

There are several auto configuration instances in Boot that requires certain types to be flagged with @Primary if they're not using the "default" name. For instance a JdbcTemplate is created for you automatically if none exists and a datasource is present. If you have more than one you should either name one dataSource or flag one of them as @Primary.

In your case, the messaging auto config for RabbitMQ expects one RabbitTemplate to be named rabbitTemplate or flag one of the three as @Primary.

This is annoying and we should do better. I've created #1702 for that.

Let me know if that works out for you. Thanks!
