                                         spring 集成rabbitmq 使用场景 

一、引入spring-rabbit的jar包

       <dependency>
          <groupId>org.springframework.amqp</groupId>
          <artifactId>spring-rabbit</artifactId>
          <version>1.7.5.RELEASE</version>
       </dependency>

二、编写application-rabbit.xml

<?xml version="1.0" encoding="UTF-8"?>

二、编写 消费者 实体类 和 controller 测试代码

package com.devframe.controller;

import java.io.UnsupportedEncodingException;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

@Controller
@Api(tags = "RabbitServerController rabbitmq测试controller")
public class RabbitServerController {

 @Autowired
 private AmqpTemplate amqpTemplate;
 

 @RequestMapping(value = "/sendMsg", method = RequestMethod.POST)
 @ResponseBody
 public String sendAmqbMsg(Model model, @RequestParam(value = "msg", defaultValue = "hello world!!!") String msg) {
  if (model != null && !"".equals(msg)) {
   amqpTemplate.convertAndSend("mq.asdfExChange", "mq.asdf.send", msg);
  } else {
   amqpTemplate.convertAndSend("mq.asdfExChange", "mq.asdf.send", "hello world");
  }
  return "success";
 }

 @RequestMapping(value = "/sendMsg2", method = RequestMethod.POST)
 @ResponseBody
 public String sendAmqbMsg2(Model model, @RequestParam(value = "msg", defaultValue = "hello world!!!") String msg) {
  if (model != null && !"".equals(msg)) {
   amqpTemplate.convertAndSend("mq.asdfExChange", "mq.asdf2.send", "这个世界很奇妙!!!");
  } else {
   amqpTemplate.convertAndSend("mq.asdfExChange", "mq.asdf2.send", "这个世界很奇妙");
  }
  return "success";
 }

 @RequestMapping(value = "/sendMsg3", method = RequestMethod.POST)
 @ResponseBody
 public String sendAmqbMsg3(Model model, @RequestParam(value = "msg", defaultValue = "hello world!!!") String msg) {
  if (model != null && !"".equals(msg)) {
   amqpTemplate.convertAndSend("mq.qwerExChange", "mq.qwer.send", "神奇的世界!!!");
  } else {
   amqpTemplate.convertAndSend("mq.qwerExChange", "mq.qwer.send", "神奇的世界");
  }
  return "success";
 }

 @RequestMapping(value = "/helloWorld", method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation("1对1 or 1对多 无交换机模式")
 public String helloWorld(Model model, @RequestParam(value = "msg", defaultValue = "1对1，无交换机模式!") String msg) {
  if (model != null && !"".equals(msg)) {
   amqpTemplate.convertAndSend("hello", msg);
  }
  return "success";
 }

 @RequestMapping(value = "/pubSub", method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation("广播发布/订阅模式")
 public String pubSub(Model model, @RequestParam(value = "msg", defaultValue = "广播发布/订阅模式") String msg) {
  if (model != null && !"".equals(msg)) {
   // 广播模式对于路由无效，所有的消费者都可以获取都消息
   amqpTemplate.convertAndSend("pubSubExchange", "", msg);
  }
  return "success";
 }

 @RequestMapping(value = "/routing", method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation("路由消息模式")
 public String routing(Model model, @RequestParam(value = "msg", defaultValue = "路由消息模式") String msg) {
  if (model != null && !"".equals(msg)) {
   String[] infoTyp = new String[] { "info", "warn", "error" };
   for (String routing : infoTyp) {
    amqpTemplate.convertAndSend("routingExchange", routing, msg);
   }
  }
  return "success";
 }

 @RequestMapping(value = "/topicMatch", method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation("主题模式")
 public String topicModal(Model model, @RequestParam(value = "msg", defaultValue = "主题模式") String msg) {
  if (model != null && !"".equals(msg)) {
   String[] infoTyp = new String[] { "P.123.asdasd", "P.456.JQBE", "P.789.WBD", "P.ASBDJBAS" };
   for (String routing : infoTyp) {
    amqpTemplate.convertAndSend("topicExchange", routing, msg);
   }
  }
  return "success";
 }

 @RequestMapping(value = "/headerModal", method = RequestMethod.POST)
 @ResponseBody
 @ApiOperation("header模式")
 public String headerModal(Model model, @RequestParam(value = "msg", defaultValue = "主题模式") String msg) throws UnsupportedEncodingException {
  if (model != null && !"".equals(msg)) {
   Map<String, Object> map = new HashMap<String, Object>();
   map.put("abc", "nb");
   map.put("def", "pl");
   map.put("jabs", "aksd");
   for (Entry<String, Object> entry : map.entrySet()) {
    MessageProperties messageProperties = new MessageProperties();
    messageProperties.setHeader(entry.getKey(), entry.getValue());
    Message message = new Message(msg.getBytes("utf-8"), messageProperties);
    amqpTemplate.convertAndSend("headerExchange", null,message);
   }
  }
  return "success";
 }
   //rpc调用未实现
}

 


public class TopicCustomer1 implements MessageListener {
 @Override
 public void onMessage(Message message) {
  // TODO Auto-generated method stub
  try {
   System.out.println(
     String.format("TopicCustomer1 receive msg ------%s%s%s", "【", new String(message.getBody(), "UTF-8"), "】"));
  } catch (UnsupportedEncodingException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }
}

每个消费者都是同样的代码，均只需实现MessageListener接口，重写 onMessage方法即可。

或者 不需要 实现 MessageListener 接口，在配置消费者监听时自定义方法。如下：


  
    
   
  1. 
    
    
     
    
    
    
    
    
     
    
      <rabbit:listener-container
     
    
    
    2. 
   
  2. 
    
    
     
    
    
    
    
    
     
    		connection-factory="connectionFactory">
     
    
    
    3. 
   
  3. 
    
    
     
    
    
    
    
    
     
    		<rabbit:listener ref="headerCustomer1" queues="headerQueue1" method="listen" />
     
    
    
    4. 
   
  4. 
    
    
     
    
    
    
    
    
     
    		<rabbit:listener ref="headerCustomer2" queues="headerQueue2" method="listen" />
     
    
    
    5. 
   
  5. 
    
    
     
    
    
    
    
    
     
    	</rabbit:listener-container>
     
    
    
    6.

method 属性 指定 的就是 两个消费者自定义的方法名称。
