rabbitmq-topic-provider项目
（1）订单消息发送者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
public class OrderSender {
@Value("${mq.config.exchange}")
private String exchange;
@Autowired
private AmqpTemplate rabbitTemplate;
public void send() {
this.rabbitTemplate.convertAndSend(this.exchange, "order.log.debug", "order.log.debug.......");
this.rabbitTemplate.convertAndSend(this.exchange, "order.log.info", "order.log.info.......");
this.rabbitTemplate.convertAndSend(this.exchange, "order.log.warn", "order.log.warn.......");
this.rabbitTemplate.convertAndSend(this.exchange, "order.log.error", "order.log.error.......");
}
}
（2）产品消息发送者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
public class ProductSender {
@Value("${mq.config.exchange}")
private String exchange;
@Autowired
private AmqpTemplate rabbitTemplate;
public void send() {
this.rabbitTemplate.convertAndSend(this.exchange, "product.log.debug", "product.log.debug.......");
this.rabbitTemplate.convertAndSend(this.exchange, "product.log.info", "product.log.info.......");
this.rabbitTemplate.convertAndSend(this.exchange, "product.log.warn", "product.log.warn.......");
this.rabbitTemplate.convertAndSend(this.exchange, "product.log.error", "product.log.error.......");
}
}
（3）用户消息发送者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
public class UserSender {
@Value("${mq.config.exchange}")
private String exchange;
@Autowired
private AmqpTemplate rabbitTemplate;
public void send() {
this.rabbitTemplate.convertAndSend(this.exchange, "user.log.debug", "user.log.debug.......");
this.rabbitTemplate.convertAndSend(this.exchange, "user.log.info", "user.log.info.......");
this.rabbitTemplate.convertAndSend(this.exchange, "user.log.warn", "user.log.warn.......");
this.rabbitTemplate.convertAndSend(this.exchange, "user.log.error", "user.log.error.......");
}
}
（4）测试类
import com.ebook.rabbitmq.OrderSender;
import com.ebook.rabbitmq.ProductSender;
import com.ebook.rabbitmq.RabbitmqTopicProvider;
import com.ebook.rabbitmq.UserSender;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = RabbitmqTopicProvider.class)
public class RabbitMqTopicApplicationTests {
@Autowired
private UserSender userSender;
@Autowired
private ProductSender productSender;
@Autowired
private OrderSender orderSender;
@Test
public void send() throws InterruptedException {
this.userSender.send();
this.productSender.send();
this.orderSender.send();
}
}
rabbitmq-topic-consumer项目
（1）Info信息接收者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = "${mq.config.queue.info}", autoDelete = "true"),//autoDelete表示队列为临时队列
exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC),
key = "*.log.info"
))
public class InfoReciver {
@RabbitHandler
public void process(String msg) {
System.out.println("接收到INFO日志：" + msg);
}
}
（2）Error信息接收者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = "${mq.config.queue.error}", autoDelete = "true"),//autoDelete表示队列为临时队列
exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC),
key = "*.log.error"
))
public class ErrorReciver {
@RabbitHandler
public void process(String msg) {
System.out.println("接收到ERROR日志：" + msg);
}
}
（3）全部消息接收者
package com.ebook.rabbitmq;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.*;
import org.springframework.stereotype.Component;
/**
* @author:JZ
* @date:2020/2/2
*/
@Component
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = "${mq.config.queue.logs}", autoDelete = "true"),//autoDelete表示队列为临时队列
exchange = @Exchange(value = "${mq.config.exchange}", type = ExchangeTypes.TOPIC),
key = "*.log.*"
))
public class LogsReciver {
@RabbitHandler
public void process(String msg) {
System.out.println("接收到ALL日志：" + msg);
}
}
