是否可以从另一个应用程序（在单独的进程中启动）连接到Spring Boot嵌入式ActiveMQ实例？

只需

BrokerService

@SpringBootApplicationpublic class So48504265Application {    public static void main(String[] args) {        SpringApplication.run(So48504265Application.class, args);    }    @Bean    public BrokerService broker() throws Exception {        BrokerService broker = new BrokerService();        broker.addConnector("tcp://localhost:61616");        return broker;    }    @Bean    public ApplicationRunner runner(JmsTemplate template) {        return args -> template.convertAndSend("foo", "AMessage");    }    @JmsListener(destination = "foo")    public void listen(String in) {        System.out.println(in);    }}

和

spring.activemq.broker-url=tcp://localhost:61616

并将其添加到您的pom
