activeMQ嵌入Java代码的使用

初学amq，根据网上学习到的一些，整理了一下amq嵌入Java代码的使用，如有错误请指出。

首先需要导入两个jar包：

activemq-all-5.5.1.jar
slf4j-nop-1.4.3.jar

import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.broker.BrokerService;
import org.apache.activemq.broker.TransportConnector;
