SSM整合RabbitMQ
1.添加pom依赖
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.7.2.RELEASE</version>
</dependency>
2.配置spring-rabbitmq.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:rabbit="http://www.springframework.org/schema/rabbit"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit-1.4.xsd">
<!-- spring-rabbit.xsd的版本要注意,很1.4以前很多功能都没有,要用跟jar包匹配的版本 -->
<bean id="jsonMessageConverter" class="org.springframework.amqp.support.converter.Jackson2JsonMessageConverter" />
<rabbit:connection-factory id="mqconnectionFactory" host="${mq.host}" port="${mq.port}"
username="${mq.username}" password="${mq.password}"/>
<!--<bean id="connectionFactory" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">-->
<!--<property name="host" ref="${mq.host}" />-->
<!--<property name="port" value="${mq.port}" />-->
<!--<property name="username" value="${mq.username}" />-->
<!--<property name="password" value="${mq.password}" ></property>-->
<!--</bean >-->
<rabbit:admin connection-factory="mqconnectionFactory" />
<!-- 给模板指定转换器 --><!-- mandatory必须设置true,return callback才生效 -->
<rabbit:template id="amqpTemplate" connection-factory="mqconnectionFactory"/>
<rabbit:queue name="miaosha.queue" />
<!-- <rabbit:direct-exchange name="DIRECT_EX" id="DIRECT_EX" >
<rabbit:bindings>
<rabbit:binding queue="miaosha.queue" />
</rabbit:bindings>
</rabbit:direct-exchange>-->
<!-- 配置consumer, 监听的类和queue的对应关系 -->
<!--定义监听器，当收到消息时会执行里面的配置-->
<rabbit:listener-container connection-factory="mqconnectionFactory" acknowledge="manual" >
<rabbit:listener ref="consumer" method="receive" queue-names="miaosha.queue"/>
</rabbit:listener-container>
<bean id="consumer" class="com.shop.rabbitmq.MQConsumer"/>
</beans>
在spring-dao.xml进行引入
<bean class="com.shop.util.EncryptPropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
<value>classpath:redis.properties</value>
<value>classpath:global.properties</value>
</list>
</property>
<property name="fileEncoding" value="utf-8"/>
</bean>
3.编写MQProducer接口及其实现类（注意是在Service包下）
package com.shop.service;
import com.shop.rabbitmq.MQMessage;
/**
* Created by Skye on 2018/7/7.
*/
public interface MQProducer {
String MIAOSHA_QUEUE = "miaosha.queue";
String QUEUE = "queue";
String TOPIC_QUEUE1 = "topic.queue";
/**
* 发送消息到指定队列
* @param msg
*/
void sendMessage(MQMessage msg);
}
MQProducer实现类
package com.shop.service.serviceImpl;
import com.shop.cache.RedisUtil;
import com.shop.rabbitmq.MQMessage;
import com.shop.service.MQProducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* Created by Skye on 2018/7/7.
*/
@Service
public class MQProducerImpl implements MQProducer {
private static Logger log = LoggerFactory.getLogger(MQProducer.class);
@Autowired
AmqpTemplate amqpTemplate ;
@Override
public void sendMessage(MQMessage msg)
{
String mm = RedisUtil.beanToString(msg);
log.info("send message:"+msg);
//发送信息
amqpTemplate.convertAndSend(MIAOSHA_QUEUE, mm);
}
}
4.写消费者
package com.shop.rabbitmq;
import com.shop.bean.LocalUser;
import com.shop.bean.MiaoshaOrder;
import com.shop.bean.MiaoshaProduct;
import com.shop.cache.RedisUtil;
import com.shop.dto.ProductExecution;
import com.shop.service.MQProducer;
import com.shop.service.MiaoshaService;
import com.shop.service.OrderService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* Created by Skye on 2018/7/7.
*/
@Service
public class MQConsumer {
@Autowired
MiaoshaService miaoshaService;
@Autowired
OrderService orderService;
private static Logger log = LoggerFactory.getLogger(MQConsumer.class);
public void rmqProducerMessage(Object object){
MQMessage MQMessage =(MQMessage) object;
System.out.println(MQMessage.getExchange());
System.out.println(MQMessage.getRouteKey());
System.out.println(MQMessage.getParams().toString());
}
@RabbitListener(queues=MQProducer.MIAOSHA_QUEUE)
public void receive(String message) {
log.info("receive message:"+message);
MQMessage mm = RedisUtil.stringToBean(message, MQMessage.class);
LocalUser localUser = mm.getUser();
MiaoshaProduct miaoshaProduct = mm.getMiaoshaProduct();
ProductExecution productExecution = miaoshaService.getMiaoshaProduct(miaoshaProduct);
miaoshaProduct = productExecution.getMiaoshaProduct();
int stock = miaoshaProduct.getMiaoshaStock();
if(stock <= 0) {
return;
}
//判断是否已经秒杀到了
MiaoshaOrder order = orderService.getMiaoshaOrder(localUser, miaoshaProduct);
if(order != null) {
return;
}
//减库存 下订单 写入秒杀订单
miaoshaService.doMiaosha(localUser, miaoshaProduct);
}
}
MQMessage类
package com.shop.rabbitmq;
import com.shop.bean.LocalUser;
import com.shop.bean.MiaoshaProduct;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
/**
* Created by Skye on 2018/7/6.
*/
public class MQMessage implements Serializable {
private static final long serialVersionUID = 1302562501680404088L;
private LocalUser user;
private MiaoshaProduct miaoshaProduct;
public LocalUser getUser() {
return user;
}
public void setUser(LocalUser user) {
this.user = user;
}
public MiaoshaProduct getMiaoshaProduct() {
return miaoshaProduct;
}
public void setMiaoshaProduct(MiaoshaProduct miaoshaProduct) {
this.miaoshaProduct = miaoshaProduct;
}
private Class<?>[] paramTypes;//参数类型
private String exchange;//交换器
private Object[] params;
private String routeKey;//路由key
public MQMessage(){}
public MQMessage(String exchange, String routeKey, Object...params)
{
this.params=params;
this.exchange=exchange;
this.routeKey=routeKey;
}
@SuppressWarnings("rawtypes")
public MQMessage(String exchange, String routeKey, String methodName, Object...params)
{
this.params=params;
this.exchange=exchange;
this.routeKey=routeKey;
int len=params.length;
Class[] clazzArray=new Class[len];
for(int i=0;i<len;i++)
clazzArray[i]=params[i].getClass();
this.paramTypes=clazzArray;
}
public byte[] getSerialBytes()
{
byte[] res=new byte[0];
ByteArrayOutputStream baos=new ByteArrayOutputStream();
ObjectOutputStream oos;
try {
oos = new ObjectOutputStream(baos);
oos.writeObject(this);
oos.close();
res=baos.toByteArray();
} catch (IOException e) {
e.printStackTrace();
}
return res;
}
public String getRouteKey() {
return routeKey;
}
public String getExchange() {
return exchange;
}
public void setExchange(String exchange) {
this.exchange = exchange;
}
public void setRouteKey(String routeKey) {
this.routeKey = routeKey;
}
public Class<?>[] getParamTypes() {
return paramTypes;
}
public Object[] getParams() {
return params;
}
}
SSM整合rabbitMQ时报错org.springframework.beans.factory.NoSuchBeanDefinitionException
