学习activemq(2)Spring boot整合activemq jms

JMS（JAVA Message Service,java消息服务）API是一个消息服务的标准或者说是规范，允许应用程序组件基于JavaEE平台创建、发送、接收和读取消息。它使分布式通信耦合度更低，消息服务更加可靠以及异步性。
消息模型
即“点对点”和“发布订阅”

2. Spring官方例子

地址http://spring.io/guides/gs/messaging-jms/
Mail.java

public class Email {    private String to;    private String body;    public Email() {    }    public Email(String to, String body) {        this.to = to;        this.body = body;    }    public String getTo() {        return to;    }    public void setTo(String to) {        this.to = to;    }    public String getBody() {        return body;    }    public void setBody(String body) {        this.body = body;    }    @Override    public String toString() {        return String.format("Email{to=%s, body=%s}", getTo(), getBody());    }}

Receiver.java

import org.springframework.jms.annotation.JmsListener;import org.springframework.stereotype.Component;import com.sonic.activemq.LogCore;@Componentpublic class Receiver {    @JmsListener(destination = "mailbox", containerFactory = "myFactory")    public void receiveMessage(Email email) {        System.out.println("Received <" + email + ">");        LogCore.BASE.info("rsv msg:{}", email);    }}

JMSTest.java

@Configurationpublic class JMSTest implements CommandLineRunner {    @Bean    public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,                DefaultJmsListenerContainerFactoryConfigurer configurer) {        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();        // This provides all boot's default to this factory, including the message converter        configurer.configure(factory, connectionFactory);        // You could still override some of Boot's default if necessary.        return factory;    }    @Bean // Serialize message content to json using TextMessage    public MessageConverter jacksonJmsMessageConverter() {        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();        converter.setTargetType(MessageType.TEXT);        converter.setTypeIdPropertyName("_type");        return converter;    }    @Autowired    JmsTemplate jmsTemplate;    @Override    public void run(String... args) throws Exception {        System.out.println("Sending an email message.");        jmsTemplate.convertAndSend("mailbox", new Email("[e-mail]", "Hello"));    }}

上面两个例子pom.xml和application.properties一样
但是要分开调试
