ActiveMQ---遇到的args输入问题

最近在学习ActiveMQ，书上一个例子是演示pub/sub原理的stock portfolio.奇怪的是，运行Publisher后控制台只显示连接成功的信息，并没有哗哗哗地刷股票信息。
仔细看了主函数后才发现它是要有输入的，但不是运行后从控制台输入。而是通过args输入。

Publisher主函数代码如下

import java.util.Hashtable;import java.util.Map;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.MapMessage;import javax.jms.Message;import javax.jms.MessageProducer;import javax.jms.Session;import org.apache.activemq.ActiveMQConnectionFactory;import org.apache.activemq.command.ActiveMQMapMessage;public class Publisher {    protected int MAX_DELTA_PERCENT = 1;    protected Map<String, Double> LAST_PRICES = new Hashtable<String, Double>();//前一次的股票价格    protected static int count = 10;    protected static int total;    protected static String brokerURL = "tcp://localhost:61616";    protected static transient ConnectionFactory factory;    protected transient Connection connection;    protected transient Session session;    protected transient MessageProducer producer;    public Publisher() throws JMSException {        factory = new ActiveMQConnectionFactory(brokerURL);        connection = factory.createConnection();        try {        connection.start();        } catch (JMSException jmse) {            connection.close();            throw jmse;        }        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);        producer = session.createProducer(null);    }    public void close() throws JMSException {        if (connection != null) {            connection.close();        }    }    public static void main(String[] args) throws JMSException {        Publisher publisher = new Publisher();        while (total < 1000) {            for (int i = 0; i < count; i++) {                publisher.sendMessage(args);            }            total += count;            System.out.println("Published '" + count + "' of '" + total + "' price messages");            try {              Thread.sleep(1000);            } catch (InterruptedException x) {            }        }        publisher.close();    }    protected void sendMessage(String[] stocks) throws JMSException {        int idx = 0;        while (true) {            idx = (int)Math.round(stocks.length * Math.random());            if (idx < stocks.length) {                break;            }        }        String stock = stocks[idx];        Destination destination = session.createTopic("STOCKS." + stock);        Message message = createStockMessage(stock, session);        System.out.println("Sending: " + ((ActiveMQMapMessage)message).getContentMap() + " on destination: " + destination);        producer.send(destination, message);    }    protected Message createStockMessage(String stock, Session session) throws JMSException {        Double value = LAST_PRICES.get(stock);        if (value == null) {            value = new Double(Math.random() * 100);        }        // lets mutate the value by some percentage        double oldPrice = value.doubleValue();        value = new Double(mutatePrice(oldPrice));        LAST_PRICES.put(stock, value);        double price = value.doubleValue();        double offer = price * 1.001;        boolean up = (price > oldPrice);        MapMessage message = session.createMapMessage();        message.setString("stock", stock);        message.setDouble("price", price);        message.setDouble("offer", offer);        message.setBoolean("up", up);        return message;    }    protected double mutatePrice(double price) {        double percentChange = (2 * Math.random() * MAX_DELTA_PERCENT) - MAX_DELTA_PERCENT;        return price * (100 + percentChange) / 100;    }}

eclipse添加args参数的方法
1.右击执行文件，如本例中的Publisher.java
run as 选中 Run Configuration…

2.选中第二个标签Arguments,在Program argument 内输入参数
参数用空格隔开

简单的例子

public class test {    public static void main(String[] args){        for(String str:args){            System.out.println(str);        }    }}
