"RABBITMQ series" Spring MVC integration RABBITMQ

First, install RABBITMQ1 under Linux, install Erlang environment

wget http://erlang.org/download/otp_src_18.2.1.tar.gz  tar xvfz otp_src_18.2.1.tar.gz   CD otp_src_18.2.1./ Configure   

2, Installation RABBITMQ

wget http://www.rabbitmq.com/releases/rabbitmq-server/vx.x.x/rabbitmq-server-generic-unix-x.x.x.tar.xz  // XY file Compression tool yum install XZ  //decompression xz-d rabbitmq-server-generic-unix-x.x.x.tar.xz  TAR-XVF rabbitmq-server-generic-unix-x.x.x.tar//move it to/usr/local/under your own custom Cp-r RABBITMQ_SERVER-X.X.X/USR/LOCAL/RABBITMQ  //Change environment variable Vi/etc/profileexport path=/usr/local/rabbitmq/sbin: $PATH  source/etc/profile// Enable MQ management mode Rabbitmq-plugins enable Rabbitmq_management   #启动后台管理  rabbitmq-server-detached   #后台运行rabbitmq  //Set port number for external use iptables-i input-p tcp--dport 15672-j ACCEPT  

3. Add Users and Permissions

Add user rabbitmqctl Add_user admin admin//Add permissions rabbitmqctl set_permissions-p "/" admin ". *". * ". *"//Add user role Rabbitmqctl SE T_user_tags Admin Administrator

　

Two, Spring MVC integration RabbitMQ1, add Pom.xml dependent jar Package

<!--https://mvnrepository.com/artifact/org.springframework.amqp/spring-rabbit--        <dependency>            <groupId>org.springframework.amqp</groupId>            <artifactid>spring-rabbit</ artifactid>            <version>1.7.5.RELEASE</version>        </dependency>

2. Add Configuration Applicationcontext.xml

<!--configuration RABBITMQ start-to-<bean id= "CONNECTIONFACTORYMQ" class= " Org.springframework.amqp.rabbit.connection.CachingConnectionFactory "> <constructor-arg value=" 192.168.181.201 "/> <property name=" username "value=" admin "/> <property name=" password "value=" ad    Min "/> <property name=" host "value=" 192.168.181.201 "/> <property name=" port "value=" 5672 "/> </bean> <bean id= "rabbitadmin" class= "Org.springframework.amqp.rabbit.core.RabbitAdmin" > <const Ructor-arg ref= "Connectionfactorymq"/> </bean> <!--Create Rabbittemplate message template class--<bean id= "Rabbittem Plate "class=" org.springframework.amqp.rabbit.core.RabbitTemplate "> <constructor-arg ref=" Connectionfactorymq "/> </bean> <!--Create a message converter for simplemessageconverter--> <bean id=" Serializermessage Converter "class=" Org.springframework.amqp.support.converter.SimpleMessageConverter "> </bean> <! --Create a persistent queue--<bean id= "queue" class= "Org.springframework.amqp.core.Queue" > <constructor-arg index= "0" value= "testqueue" ></constructor-arg> <constructor-arg index= "1" value= "true" ></constructor-a  Rg> <constructor-arg index= "2" value= "false" ></constructor-arg> <constructor-arg index= "3" Value= "true" ></constructor-arg> </bean> <!--Create a type of exchanger and persist--<bean id= "Topicexchange" cl ass= "Org.springframework.amqp.core.TopicExchange" > <constructor-arg index= "0" value= "Testexchange" ></ Constructor-arg> <constructor-arg index= "1" value= "true" ></constructor-arg> <constructor-a RG index= "2" value= "false" ></constructor-arg> </bean> <util:map id= "Arguments" > </util:ma P> <!--binding Exchanger Queue--<bean id= "binding" class= "org.springframework.amqp.core.Binding" > <const Ructor-arg index= "0" vaLue= "Testqueue" ></constructor-arg> <constructor-arg index= "1" value= "QUEUE" ></constructor-arg&        Gt <constructor-arg index= "2" value= "Testexchange" ></constructor-arg> <constructor-arg index= "3" value= "Testqueue" ></constructor-arg> <constructor-arg index= "4" value= "#{arguments}" ></ Constructor-arg> </bean> <!--processing class for receiving messages--<bean id= "Rqmconsumer" class= "Com.slp.mq.RmqConsumer "></bean> <bean id=" Messagelisteneradapter "class=" Org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter "> <constructor-arg ref="        Rqmconsumer "/> <property name=" Defaultlistenermethod "value=" Rmqproducermessage "></property> <property name= "Messageconverter" ref= "Serializermessageconverter" ></property> </bean> <!--for The message listens to the container class Simplemessagelistenercontainer, and the listener queue queues can pass multiple--<bean id= "Listenercontainer" Class= "Org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer" > <property name= "Queues" ref = "queue" ></property> <property name= "ConnectionFactory" ref= "CONNECTIONFACTORYMQ" ></property > <property name= "MessageListener" ref= "Messagelisteneradapter" ></property> </bean> < Bean id= "Rmqproducer" class= "Com.slp.mq.RmqProducer" ></bean> <!--configuration Rabbitmq End--

3. Message entity class

Package Com.slp.mq;import java.io.*;/** * @author SANGLP * @create 2018-02-06 * @desc Rabbit Message class **/public class Rabb    Itmessage implements Serializable {/** * parameter type */private class<?>[] paramtypes;    /** * EXCHANGER */private String exchange;    Private object[] params;    /** * Route key */private String Routekey; Public Rabbitmessage () {} public Rabbitmessage (string Exchange, String routekey,object...params) {This.exc        hange = Exchange;        This.params = params;    This.routekey = Routekey; } @SuppressWarnings ("Rawtypes") public rabbitmessage (String exchange,string routekey,string Methodname,object...para        ms) {This.params=params;        This.exchange=exchange;        This.routekey=routekey;        int len=params.length;        Class[] Clazzarray=new Class[len];        for (int i=0;i<len;i++) {Clazzarray[i] = Params[i].getclass ();    } This.paramtypes=clazzarray; } publiC byte[] Getserialbytes () {byte[] res = new Byte[0];       Bytearrayoutputstream BAOs = new Bytearrayoutputstream ();       ObjectOutput Oos;           try {oos = new ObjectOutputStream (BAOs);           Oos.writeobject (this);           Oos.close ();       res = Baos.tobytearray ();       } catch (IOException e) {e.printstacktrace ();   } return res;    } public class<?>[] Getparamtypes () {return paramtypes;    } public void Setparamtypes (class<?>[] paramtypes) {this.paramtypes = Paramtypes;    } public String Getexchange () {return exchange;    public void Setexchange (String exchange) {this.exchange = Exchange;    } public object[] Getparams () {return params;    } public void SetParams (object[] params) {this.params = params;    } public String Getroutekey () {return routekey;    } public void Setroutekey (String routekey) {this.routekey = Routekey; }} 

4. Producers

Package Com.slp.mq;import Org.springframework.amqp.rabbit.core.rabbittemplate;import javax.annotation.Resource;/* * * @author SANGLP * @create 2018-02-06 14:19 * @desc producer **/public class Rmqproducer {    @Resource    private Rabbitte Mplate rabbittemplate;    /**     * Send Message     * @param msg */public    void SendMessage (Rabbitmessage msg) {        System.out.println ( Rabbittemplate.getconnectionfactory (). GetHost ());        System.out.println (Rabbittemplate.getconnectionfactory (). Getport ());        System.out.println ("msg" +msg);        Rabbittemplate.convertandsend (Msg.getexchange (), Msg.getroutekey (), msg);        SYSTEM.OUT.PRINTLN ("Send Complete");}    }

　　

5. Consumers

Package com.slp.mq;/** * @author SANGLP * @create 2018-02-06 14:23 * @desc Consumer **/public class Rmqconsumer {public    vo ID rmqproducermessage (Object object) {        System.out.println ("Pre-consumption");        Rabbitmessage rabbitmessage = (rabbitmessage) object;        System.out.println (Rabbitmessage.getexchange ());        System.out.println (Rabbitmessage.getroutekey ());        System.out.println (Rabbitmessage.getparams (). toString ());}    }

　　

6. Test class

Package Com.slp;import Com.slp.mq.rabbitmessage;import Com.slp.mq.rmqconsumer;import com.slp.mq.rmqproducer;import Org.junit.before;import Org.junit.test;import Org.springframework.context.applicationcontext;import Org.springframework.context.support.filesystemxmlapplicationcontext;import Java.util.hashmap;import java.util.map;/** * @author SANGLP * @create 2018-02-06 14:36 * @desc MQ Test class **/public class Mqtest {private rmqproduce    R Rmqproducer;    Private Rmqconsumer Rqmconsumer; @Before public void SetUp () throws Exception {//classpathxmlapplicationcontext context = new Classpathxmlapplic        Ationcontext ("D:/web-back/web-back/myweb/web/web-inf/applicationcontext.xml");        Context.start ();        String path= "Web/web-inf/applicationcontext.xml";        ApplicationContext context = new Filesystemxmlapplicationcontext (path);        Rmqproducer = (rmqproducer) context.getbean ("Rmqproducer");    Rqmconsumer = (Rmqconsumer) context.getbean ("Rqmconsumer"); } @TeSt public void Test () {String exchange = "Testexchange";        String Routekey = "Testqueue";       String methodName = "Test";            parameter for (int i=0;i<10;i++) {map<string,object> param=new hashmap<string, object> ();            Param.put ("Data", "Hello");            Rabbitmessage msg=new rabbitmessage (exchange,routekey, MethodName, param);        Send Message Rmqproducer.sendmessage (msg);    }//Rqmconsumer.rmqproducermessage (msg); }}

　

Operation Result:

Before the consumer is opened:
