java springboot 集成activeMQ（保姆级别教程）

java springboot 集成activeMQ

1.配置信息

spring: 
  # 配置消息队列
  activemq:
    broker-url: tcp://127.0.0.1:61616
    user: admin
    password: admin

2.ActiveMqConfig 消息队列配置信息

import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.config.SimpleJmsListenerContainerFactory;
import org.springframework.jms.core.JmsMessagingTemplate;

import javax.jms.ConnectionFactory;

@Configuration
@EnableJms //启动消息队列
public class ActiveMqConfig {

    @Value("${spring.activemq.broker-url}")
    private String brokerUrl;

    @Value("${spring.activemq.user}")
    private String username;

    @Value("${spring.activemq.password}")
    private String password;

    @Bean
    public ConnectionFactory connectionFactory(){
        return new ActiveMQConnectionFactory(username, password, brokerUrl);
    }

    @Bean
    public JmsMessagingTemplate jmsMessageTemplate(){
        return new JmsMessagingTemplate(connectionFactory());
    }

    // 在Queue模式中，对消息的监听需要对containerFactory进行配置
    @Bean("queueListener")
    public JmsListenerContainerFactory<?> queueJmsListenerContainerFactory(ConnectionFactory connectionFactory){
        SimpleJmsListenerContainerFactory factory = new SimpleJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setPubSubDomain(false);
        return factory;
    }

}

3.封装发送信息方法

• 发送信息接口

import javax.jms.Destination;

public interface IMQSendMsgService {
    /**
     * activeMq发送信息
     * @param destination
     * @param message
     */
    public void mqSendMessage(Destination destination, final String message);
}

• 接口实现

import lombok.extern.slf4j.Slf4j;
import org.jeecg.common.system.activemq.ISendMsgService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

import javax.jms.Destination;

@Slf4j
@Service
public class MQSendMsgServiceImpl implements IMQSendMsgService {

    @Autowired
    public JmsMessagingTemplate jmsMessagingTemplate;


    @Override
    public void mqSendMessage(Destination destination, String message) {
        jmsMessagingTemplate.convertAndSend(destination, message);
    }
}

4.消息队列在项目中的使用

4.1消息队列发送信息

	// 下单后记录商品项列表
    @Value("${spring.activemq.place-order-record-product-items}")
    private String placeOrderRecordProductItems;
	
	@Autowired
    IMQSendMsgService mqSendMsgService;

	@PostMapping(value = "/send")
	public String sendMSG(@RequestBody User user){
		String orderHistoryStr = JSON.toJSONString(user);
        mqSendMsgService.mqSendMessage(new ActiveMQQueue(placeOrderRecordProductItems), orderHistoryStr);
	}
            

4.2消息队列监听获取消费消息

@Slf4j
@Component
public class ActiveMQListenSendMsg {

	@Autowired
   IMQSendMsgService mqSendMsgService;
   
	@JmsListener(destination="${spring.activemq.send-msg-after-execute-flow}", containerFactory="queueListener")
    public void AfterExecuteFlowSendMag(String message){
	// 业务代码写在这里
	}
}
