RabbitMQ中如何進行SSM框架整合xml配置

這期內容當中小編將會給大家帶來有關RabbitMQ中如何進行SSM框架整合xml配置，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

      前提：jdk1.8，本博客使用的是RabbitTemplate模版，用封裝好的方法，不再使用 

      還有一個重點，自己一定要會使用rabbitmq服務器，自己創建exchange、queue等，不然使用該博客的話，會報錯的。

      兩種方法：topic模式以及延遲隊列的使用

1、pom

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>4.5.16</version>
</dependency>

<dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-rabbit</artifactId>
    <version>1.7.11.RELEASE</version>
</dependency>

2、application.properties

# rabbitmq 消息配置
rabbitmq.addresses=localhost:5672
rabbitmq.virtual-host=/
rabbitmq.username=guest
rabbitmq.password=guest
rabbitmq.channel-cache-size=50
rabbitmq.concurrentConsumers=3
rabbitmq.maxConcurrentConsumers=10
# 確認方式 MANUAL 手動，AUTO 自動，NONE 自動確認
rabbitmq.acknowledgeMode=MANUAL
# 線程池數量 = 并發數 * 監聽數
rabbitmq.task-executor.pool-size=100

3、spring-rabbit.xml

4、監聽器

import cn.hutool.core.date.DateUtil;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;

import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;

/**
 * @Author:MuJiuTian
 * @Description: RabbitMq延遲隊列 https://blog.csdn.net/m912595719/article/details/83787486
 * ChannelAwareMessageListener(Message memssage,Channel channel) MessageListener(Message message)
 * @Date: Created in 下午4:17 2019/8/12
 */

public class DelayListener implements MessageListener {

    @Autowired
    RabbitTemplate rabbitTemplate;

    private static final ObjectMapper MAPPER = new ObjectMapper();

    @Override
    public void onMessage(Message message) {
        try {
            JsonNode jsonData = MAPPER.readTree(message.getBody());
            System.out.println("延遲隊列時間為："+DateUtil.format(new Date(), DateFormat.getDateTimeInstance()));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.platform.service.SeckillService;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.beans.factory.annotation.Autowired;

/**
 * @Author:MuJiuTian
 * @Description: 秒殺消費者消費消息，監聽執行業務邏輯處理
 * @Date: Created in 下午5:01 2019/8/14
 */
public class SeckillHandler implements MessageListener {

    @Autowired
    SeckillService seckillService;

    private static final ObjectMapper MAPPER = new ObjectMapper();

    @Override
    public void onMessage(Message message) {
        try {
            //隊列中繼續執行秒殺
            JsonNode jsonData = MAPPER.readTree(message.getBody());
            String goodsId = jsonData.get("goodsId").asText();
            int productId = jsonData.get("productId").asInt();
            int userId    = jsonData.get("userId").asInt();
            int sellerNum = jsonData.get("sellerNum").asInt();
            //開始秒殺
            seckillService.seckillRedis(goodsId,productId,sellerNum,userId);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

5、實體類

public class Mail implements Serializable {
    private static final long serialVersionUID = -8140693840257585779L;
    private String mailId;
    private String country;
    private Double weight;


    public Mail() {
    }

    public Mail(String mailId, String country, double weight) {
        this.mailId = mailId;
        this.country = country;
        this.weight = weight;
    }

    public String getMailId() {
        return mailId;
    }

    public void setMailId(String mailId) {
        this.mailId = mailId;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public double getWeight() {
        return weight;
    }

    public void setWeight(double weight) {
        this.weight = weight;
    }

    @Override
    public String toString() {
        return "Mail [mailId=" + mailId + ", country=" + country + ", weight="
                + weight + "]";
    }
}

6、controller

/**
 * topic：通配符模式
 */
@GetMapping(value = "/test7")
public void test11(){
    Mail mail = new Mail("21","China",27.2);
    System.out.println("topic模式發送數據到消息隊列"+DateUtil.format(new Date(), DateFormat.getDateTimeInstance()));
    rabbitTemplate.convertAndSend("IExchange","lazy.dtb",mail);
}



/**
 * 死信隊列 long等待時間，目前測試為：自動消費
 */
@GetMapping(value = "/test8")
public void test13(long time) throws IOException {
    Mail mail = randomMail();
    System.out.println("延遲隊列：dlx方式"+DateUtil.format(new Date(), DateFormat.getDateTimeInstance()));
    rabbitTemplate.convertAndSend("dlx_delay_exchange","dlx_delay_road", mail, message -> {
        message.getMessageProperties().setExpiration(time + "");
        return message;
    });
}


/**
 * 隨機創建一個Mail實體對象，供接口測試
 */
public static Mail randomMail() {
    Mail mail = new Mail();
    mail.setMailId(new Random().nextInt(100)+"");
    mail.setCountry("China");
    mail.setWeight(new Random().nextDouble());
    return mail;
}
