今天,我们将研究Spring AMQP RabbitMQ示例应用程序。
在本文中,我们将开发一个Spring AMQP RabbitMQ Messaging应用程序。
让我们现在开始。
Spring AMQP RabbitMQ示例
让我们开始使用Maven,Eclipse IDE和RabbitMQ Server开发Spring AMQP RabbitMQ Messaging应用程序。
对于所有其他Java IDE都是一样的。
请一一执行以下步骤:
- 在Eclipse IDE中创建Maven Java项目
- 开发Spring AMQP Publisher程序
package com.tp.spring.amqp.rabbit; import org.springframework.amqp.core.AmqpTemplate; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringAMQPRabbitSender { private final String SENDER_XML = "springamqp-rabbit-sender-context.xml"; public static void main(String[] args) throws Exception { AmqpTemplate amqpTemplate = (AmqpTemplate)(new ClassPathXmlApplicationContext(SENDER_XML)).getBean("amqpTemplate"); int messagCount = 0; while (messagCount < 10){ amqpTemplate.convertAndSend("tp.routingkey.1", "Message # " + messagCount++); } System.out.println( messagCount + " message(s) sent successfully."); } }
- 配置Spring AMQP Publisher所需的bean:springamqp-rabbit-sender-context.xml
<?xml version="1.0"encoding="UTF-8"?> <beans xmlns="https://www.springframework.org/schema/beans" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="https://www.springframework.org/schema/rabbit" xsi:schemaLocation="https://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans-3.1.xsd https://www.springframework.org/schema/rabbit https://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd"> <rabbit:connection-factory id="connectionFactory" host="localhost" username="tpuser" password="tpuser" <rabbit:admin connection-factory="connectionFactory" <rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="tpExchange" </beans>
- 开发Spring AMQP Consumer(Spring MDP)程序
package com.tp.spring.amqp.rabbit; import org.springframework.amqp.core.Message; import org.springframework.amqp.core.MessageListener; //Spirng MDP(Message Driven POJO) public class SpringAMQPRabbitAyncListener implements MessageListener { @Override public void onMessage(Message message) { System.out.println("Listener received message = " + new String(message.getBody())); } }
- 配置Spring AMQP Consumer需要的bean:springamqp-rabbt-listener-context.xml
<?xmlversion="1.0"encoding="UTF-8"?> <beans xmlns="https://www.springframework.org/schema/beans" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="https://www.springframework.org/schema/rabbit" xsi:schemaLocation="https://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans-3.1.xsd https://www.springframework.org/schema/rabbit https://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd"> <rabbit:connection-factory id="connectionFactory" host="localhost" username="tpuser" password="tpuser" <rabbit:admin connection-factory="connectionFactory" <rabbit:queue id="tpQueue" <rabbit:topic-exchange id="tpExchange" name="tpExchange"> <rabbit:bindings> <rabbit:binding queue="tpQueue" pattern="tp.routingkey.1"> </rabbit:binding> </rabbit:bindings> </rabbit:topic-exchange> <bean id="asyncListener" class="com.tp.spring.amqp.rabbit.SpringAMQPRabbitAyncListener" <rabbit:listener-container id="myListenerContainer" connection-factory="connectionFactory"> <rabbit:listener ref="asyncListener" queue-names="tpQueue" </rabbit:listener-container> </beans>
- 开发Spring AMQP Rabbit Container程序以初始化Spring IOC Container
package com.tp.spring.amqp.rabbit; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringAMQPRabbitlListenerContainer { public static void main(String[] args) { //Initialize Spring IOC Container new ClassPathXmlApplicationContext("springamqp-rabbt-listener-context.xml"); } }
- 最终的pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="https://maven.apache.org/POM/4.0.0" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://maven.apache.org/POM/4.0.0 https://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.tp</groupId> <artifactId>spring-amqp-rabbitmq</artifactId> <name>spring-amqp-rabbitmq</name> <packaging>jar</packaging> <version>1.0.0</version> <properties> <java-version>1.6</java-version> <org.springframework-version>3.1.1.RELEASE</org.springframework-version> <org.aspectj-version>1.6.10</org.aspectj-version> <org.slf4j-version>1.6.6</org.slf4j-version> </properties> <dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework-version}</version> <exclusions> <!-- Exclude Commons Logging in favor of SLF4j --> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework-version}</version> </dependency> <!-- AspectJ --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>${org.aspectj-version}</version> </dependency> <!-- Logging --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${org.slf4j-version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>${org.slf4j-version}</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${org.slf4j-version}</version> <scope>runtime</scope> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.15</version> <exclusions> <exclusion> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> </exclusion> <exclusion> <groupId>javax.jms</groupId> <artifactId>jms</artifactId> </exclusion> <exclusion> <groupId>com.sun.jdmk</groupId> <artifactId>jmxtools</artifactId> </exclusion> <exclusion> <groupId>com.sun.jmx</groupId> <artifactId>jmxri</artifactId> </exclusion> </exclusions> <scope>runtime</scope> </dependency> <!-- @Inject --> <dependency> <groupId>javax.inject</groupId> <artifactId>javax.inject</artifactId> <version>1</version> </dependency> <!-- Servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- Test --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.7</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-rabbit</artifactId> <version>1.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-amqp</artifactId> <version>1.1.4.RELEASE</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-eclipse-plugin</artifactId> <version>2.9</version> <configuration> <additionalProjectnatures> <projectnature>org.springframework.ide.eclipse.core.springnature</projectnature> </additionalProjectnatures> <additionalBuildcommands> <buildcommand>org.springframework.ide.eclipse.core.springbuilder</buildcommand> </additionalBuildcommands> <downloadSources>true</downloadSources> <downloadJavadocs>true</downloadJavadocs> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.5.1</version> <configuration> <source>1.6</source> <target>1.6</target> <compilerArgument>-Xlint:all</compilerArgument> <showWarnings>true</showWarnings> <showDeprecation>true</showDeprecation> </configuration> </plugin> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.2.1</version> <configuration> <mainClass>org.test.int1.Main</mainClass> </configuration> </plugin> </plugins> </build> </project>
- 我们最终的Maven项目结构
使用RabbitMQ服务器测试Spring AMQP RabbitMQ示例
- 运行AMQP Publisher并观察RabbitMQ队列中的消息
在这里我们可以看到AMQP Publisher成功发送了10条消息。
- RabbitMQ控制台在队列中显示10条消息
其中我们可以看到RabbitMQ队列已成功从AMQP Publisher接收到10条消息。
- 运行AMQP Consumer并在Eclipse IDE中观察消息
其中我们可以看到AMQP消费者从RabbitMQ队列中逐条接收每个消息。
- RabbitMQ控制台在队列中显示0条消息
在这里我们可以观察到RabbitMQ队列中有0条消息,这意味着AMQP消费者已成功接收了所有消息。
