activemq实验

实验环境：activemq4.1.1/spring1.2.8

思路：使用spring的jmsTemplate来封装jms的具体操作，使用SimpleMessageConverter把string和object转换成message

spring配置： 

xml 代码

<beans>
    <bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616"/>
    </bean>

    <bean id="messageConverter" class="org.springframework.jms.support.converter.SimpleMessageConverter"/>

    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory">
            <bean class="org.springframework.jms.connection.SingleConnectionFactory">
                <property name="targetConnectionFactory" ref="jmsConnectionFactory"/>
            </bean>
        </property>
        <property name="defaultDestinationName" value="TEST.FOO"/>
        <property name="pubSubDomain" value="false"/>
        <property name="deliveryMode" value="2"/>
        <property name="messageConverter" ref="messageConverter"/>
    </bean>

    <bean id="messageProducter" class="jms.MessageProducter">
        <property name="jmsTemplate" ref="jmsTemplate"/>
    </bean>
</beans>

代码：

java 代码

public class MessageProducter {
    private JmsTemplate jmsTemplate;
    private int messageSize = 255;

    public void sendMessage(){
        for(int i=5;i<10;i++){
            jmsTemplate.convertAndSend(createMessageText(i));
        }
    }

    private String createMessageText(int index) {
        StringBuffer buffer = new StringBuffer(messageSize);
        buffer.append("Message: " + index + " sent at: " + new Date());
        if (buffer.length() > messageSize) {
            return buffer.substring(0, messageSize);
        }
        for (int i = buffer.length(); i < messageSize; i++) {
            buffer.append(' ');
        }
        return buffer.toString();
    }

    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

    public static void main(String[] args){
        ApplicationContext context = new ClassPathXmlApplicationContext("jms/spring*.xml");
        MessageProducter producter = (MessageProducter) context.getBean("messageProducter");
        producter.sendMessage();
        ((AbstractApplicationContext) context).close();
    }
}
