Introduction Active MQ is a message queue manager, middleware used for communication. Now let me introduce to you how to use ActiveMQ to test the applet.
First you need to download ActiveMQ and modify the memory
Modify activemq.bat in the bin directory
Add
set ACTIVEMQ_OPTS=-Xms1G -Xmx1G
in the last line After saving, execute the bat file
New maven project
Add dependencies to the pom file
<dependencies> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> <!--我的mq版本为5.9.0--> <version>5.9.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-broker --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-broker</artifactId> <version>5.10.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-client --> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-client</artifactId> <version>5.14.0</version> </dependency> </dependencies>
Sender program
import org.apache.activemq.ActiveMQConnection;import org.apache.activemq. ActiveMQConnectionFactory;import javax.jms.*;public class Send { // private static final int SEND_NUMBER = 10; public static void main(String[] args){ //ConnectionFactory:连接工厂,JMS用它创建连接 ConnectionFactory connectionFactory; //Connection:JMS客户端到JMS Provider的连接 Connection connection = null; //Session:一个发送或接收消息的线程 Session session; //Destination:消息的目的地;消息的接收者 Destination destination; //MessageProducer:消息发送者 MessageProducer producer; //TextMessage message; //构造ConnectionFactory实例对象,此处采用ActiveMQ的实现jar connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "tcp://localhost:61616" ); try{ //构造从工厂得到连接对象 connection = connectionFactory.createConnection(); //启动 connection.start(); //获取操作连接 session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE); //获取session注意参数值test是一个服务器的queue,须在ActiveMQ的console配置 destination = session.createQueue("test"); //得到发送者 producer = session.createProducer(destination); //设置不持久化,实际情况请根据项目决定 producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); //构造消息,这里写死了,项目就是参数,或者方法获取 sendMessage(session,producer); session.commit(); }catch (Exception e){ e.printStackTrace(); }finally { try { if(null != connection) connection.close(); }catch (Throwable ignore){} } } public static void sendMessage(Session session, MessageProducer producer) throws Exception{ for (int i = 1; i <= 100000; i++){ TextMessage message = session.createTextMessage("今日天气asda" + i);//发送消息到目的地 System.out.println("发送:"+message.getText()); producer.send(message); } } }
Receiver program
import org.apache.activemq.ActiveMQConnection;import org.apache.activemq. ActiveMQConnectionFactory;import javax.jms.*;public class revice { public static void main(String[] args) { ConnectionFactory connectionFactory; Connection connection = null; Session session; Destination destination; //接收者-消费者 MessageConsumer messageConsumer; connectionFactory = new ActiveMQConnectionFactory( ActiveMQConnectionFactory.DEFAULT_USER, ActiveMQConnectionFactory.DEFAULT_PASSWORD, "tcp://localhost:61616"); try{ connection = connectionFactory.createConnection(); connection.start(); session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE); destination = session.createQueue("test"); messageConsumer = session.createConsumer(destination); while(true){ TextMessage message = (TextMessage) messageConsumer.receive(1000); if(null != message){ System.out.println("收到:"+message.getText()); }else{ break; } message.acknowledge(); } }catch(Exception ex){ ex.printStackTrace(); }finally{ try{ if(null != connection){ connection.close(); } }catch(Throwable ig){ } } } }

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
