通过弹簧集成自动配置ActiveMQ(Autoconfiguration of ActiveMQ with spring integration)

 在当前版本中，spring boot还可以在检测到ActiveMQ在类路径上可用时配置ConnectionFactory。 如果存在代理，则会自动启动并配置嵌入式代理。 
 
 使用JMSTemplate时似乎也是如此。 如果我想使用弹簧集成自动配置，那么不幸的是这不起作用。 ActiveMQ似乎是在弹簧集成后配置的。 缺少连接工厂的Spring引导报告错误。 我正在使用spring boot版本1.1.4和最新版本的spring集成。 
 
 我从spring boot获得了这个堆栈跟踪： 
 
2014-08-08 09:24:21.050 ERROR 6728 --- [           main]

 对我来说，弹簧启动自动配置中的依赖关系似乎与spring集成和jms模板不一致。 标准JMS自动配置如下所示： 
 
@ConditionalOnClass(JmsTemplate.class)
@ConditionalOnBean(ConnectionFactory.class)
@EnableConfigurationProperties(JmsProperties.class)
@AutoConfigureAfter({ HornetQAutoConfiguration.class, 
ActiveMQAutoConfiguration.class })
public class JmsAutoConfiguration 
 
 Spring集成如下所示： 
 
@Configuration
@ConditionalOnClass(EnableIntegration.class)
@AutoConfigureAfter(JmxAutoConfiguration.class)
public class IntegrationAutoConfiguration {
 
 对于连接工厂和活动mq弹簧集成创建的动态jms模板，不应该至少有某种自动配置。 考虑到弹簧引导参考文档，我期望正确的自动配置与jms弹簧集成？ 

In current versions spring boot can also configure a ConnectionFactory when it detects that ActiveMQ is available on the classpath. If the broker is present, an embedded broker is started and configured automatically.
 
This seems to be true when using the JMSTemplate. If I want to use spring integration auto configuration then unfortunately this does not work. ActiveMQ seems to be configured AFTER spring integration. Spring boot reports error for missing connection factory. I am using spring boot version 1.1.4 and most current version of spring integration for this.
 
I get this stacktrace from spring boot:

For me it seems that the dependencies in spring boot auto configurations are not correct with respect of spring integration and jms template. Standard JMS auto configuration looks like the following:
 
@ConditionalOnClass(JmsTemplate.class)
@ConditionalOnBean(ConnectionFactory.class)
@EnableConfigurationProperties(JmsProperties.class)
@AutoConfigureAfter({ HornetQAutoConfiguration.class, 
ActiveMQAutoConfiguration.class })
public class JmsAutoConfiguration 
 
Spring integration looks like the following:
 
@Configuration
@ConditionalOnClass(EnableIntegration.class)
@AutoConfigureAfter(JmxAutoConfiguration.class)
public class IntegrationAutoConfiguration {
 
Shouldn't there be at least some kind of auto configuration for the dynamic jms template that spring integration creates regarding connection factory and active mq. Considering the spring boot ref docs I would expect correct auto configuration with jms for spring integration as well?
