如何使用Spring JMS发布JMS主题？

import javax.jms.ConnectionFactory;
import javax.jms.Topic;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.connection.SingleConnectionFactory;

@Configuration
public class JmsConfig {

    @Bean
    public ConnectionFactory connectionFactory() {
        // 配置JMS连接工厂
        SingleConnectionFactory connectionFactory = new SingleConnectionFactory();
        connectionFactory.setTargetConnectionFactory(new ActiveMQConnectionFactory("tcp://localhost:61616"));
        return connectionFactory;
    }

    @Bean
    public JmsTemplate jmsTemplate(ConnectionFactory connectionFactory) {
        // 配置JMS模板
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(connectionFactory);
        return jmsTemplate;
    }

    @Bean
    public Topic topic() {
        // 配置JMS目的地
        return new ActiveMQTopic("myTopic");
    }

    // 其他配置...

}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Component;

@Component
public class JmsPublisher {

    @Autowired
    private JmsTemplate jmsTemplate;

    @Autowired
    private Topic topic;

    public void publishMessage(final String message) {
        // 发布消息
        jmsTemplate.send(topic, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(message);
            }
        });
    }

}
