您可以在类路径上定义自定义activemq配置，并使用以下内容加载：

@Profile("embedded-activemq")
@ImportResource("classpath:embedded-activemq.xml")
@Configuration
  public class EmbeddedActiveMQConfig {
}

您将需要用于activemq的spring namespacehandler（在spring boot starter activemq中不存在）：

<dependency>
  <groupId>org.apache.activemq</groupId>
  <artifactId>activemq-spring</artifactId>
</dependency>

然后，您可以获取与您的activemq版本相对应的官方activemq.xml，并将其调整为spring嵌入式上下文，例如：
