java远程连接调用Rabbitmq的实例代码

本文介绍了java远程连接调用Rabbitmq，分享给大家，希望此文章对各位有所帮助。

打开IDEA创建一个maven工程（Java就可以了）。

pom.xml文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.zhenqi</groupId> <artifactId>rabbitmq-study</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>rabbitmq-study</name> <url>http://maven.apache.org</url> <properties>  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies>  <dependency>   <groupId>junit</groupId>   <artifactId>junit</artifactId>   <version>4.12</version>   <scope>test</scope>  </dependency>  <!-- https://mvnrepository.com/artifact/com.rabbitmq/amqp-client -->  <dependency>   <groupId>com.rabbitmq</groupId>   <artifactId>amqp-client</artifactId>   <version>4.1.0</version>   <exclusions>    <exclusion>     <groupId>org.slf4j</groupId>     <artifactId>slf4j-api</artifactId>    </exclusion>   </exclusions>  </dependency>  <dependency>   <groupId>org.slf4j</groupId>   <artifactId>slf4j-log4j12</artifactId>   <version>1.7.21</version>  </dependency>  <dependency>   <groupId>commons-lang</groupId>   <artifactId>commons-lang</artifactId>   <version>2.6</version>  </dependency> </dependencies></project>

为了能远程访问rabbitmq，则需要编辑 /etc/rabbitmq/rabbitmq.conf,添加以下内容。

[  {rabbit, [{tcp_listeners, [5672]}, {loopback_users, ["asdf"]}]} ]

添加administrator角色

rabbitmqctl set_user_tags openstack administrator

创建抽象队列 EndPoint.java

package com.zhenqi;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;/** * Created by wuming on 2017/7/16. */public abstract class EndPoint {  protected Channel channel;  protected Connection connection;  protected String endPointName;  public EndPoint(String endpointName) throws Exception {    this.endPointName = endpointName;    //创建一个连接工厂 connection factory    ConnectionFactory factory = new ConnectionFactory();    //设置rabbitmq-server服务IP地址    factory.setHost("192.168.146.128");    factory.setUsername("openstack");    factory.setPassword("rabbitmq");    factory.setPort(5672);    factory.setVirtualHost("/");    //得到 连接    connection = factory.newConnection();    //创建 channel实例    channel = connection.createChannel();    channel.queueDeclare(endpointName, false, false, false, null);  }  /**   * 关闭channel和connection。并非必须，因为隐含是自动调用的。   * @throws IOException   */  public void close() throws Exception{    this.channel.close();    this.connection.close();  }}
