rocketmq搭建和测试
准备工作搭建rocketmq:
1.命令启动mqbroker：mqbroker.cmd -n localhost:9876 autoCreateTopicEnable=true（保证topic自动创建）
2.启动mqnamesrv.cmd
生产者-客户端初始化：
package com.simoo.mq; import org.apache.rocketmq.client.exception.MQClientException; import org.apache.rocketmq.client.producer.DefaultMQProducer; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import javax.annotation.PostConstruct; import javax.annotation.PreDestroy; @Component public class MsgProducer { @Value("${rocketmq.producer.producerGroup}") private String producerGroup; @Value("${rocketmq.namesrvAddr}") private String namesrvAddr; private DefaultMQProducer mqProducer; //调用方注入MsgProducer后 通过这个方法获取配置好的DefaultMQProducer public DefaultMQProducer getMqProducer() { return mqProducer; } @PostConstruct public void initMQ() { mqProducer = new DefaultMQProducer(producerGroup); mqProducer.setNamesrvAddr(namesrvAddr); mqProducer.setVipChannelEnabled(false); try { mqProducer.start(); } catch (MQClientException e) { e.printStackTrace(); } } @PreDestroy public void destory() { mqProducer.shutdown(); } }
