一．创建spring boot项目

org.springframework.boot            spring-boot-starter-data-redis        org.springframework.boot            spring-boot-starter-web        com.alibaba            fastjson            1.2.41

二．编辑yml配置文件

server:  port: 7888# 日志配置logging:  config: classpath:log/logback.xml  level:    cn.com.dhcc: info    org.springframework: info    org.springframework.web: info    com.alibaba.nacos.client.naming: errorspring:  redis:     host: localhost     port: 6379     password: *********     database: 1     jedis:      pool:        max-idle: 8        max-active: 8        max-wait: -1        min-idle: 0     timeout: 5000

三．配置Redis

@Configurationpublic class RedisConfiguration {    /**     * 实例化 RedisTemplate 对象     *     * @return     */    @Bean("RedisTemplateS")    public RedisTemplate functionDomainRedisTemplate(RedisConnectionFactory redisConnectionFactory) {        RedisTemplate redisTemplate = new RedisTemplate<>();        initDomainRedisTemplate(redisTemplate, redisConnectionFactory);        return redisTemplate;    }    /**     * 设置数据存入 redis 的序列化方式,并开启事务     *      * @param redisTemplate     * @param factory     */    private void initDomainRedisTemplate(@Qualifier("RedisTemplateS") RedisTemplate redisTemplate, RedisConnectionFactory factory) {        // 如果不配置Serializer，那么存储的时候缺省使用String，如果用User类型存储，那么会提示错误User can't cast to        // String！        redisTemplate.setKeySerializer(new StringRedisSerializer());        redisTemplate.setHashKeySerializer(new StringRedisSerializer());        FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);        redisTemplate.setHashValueSerializer(fastJsonRedisSerializer);        redisTemplate.setValueSerializer(fastJsonRedisSerializer);        //redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());        //redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());        // 开启事务        redisTemplate.setEnableTransactionSupport(true);        redisTemplate.setConnectionFactory(factory);    }    /**     * 注入封装RedisTemplate @Title: redisUtil @return RedisUtil @date     *      */    @Bean(name = "redisUtils")    public RedisUtils redisUtil(@Qualifier("RedisTemplateS") RedisTemplate redisTemplate) {        RedisUtils redisUtil = new RedisUtils();        redisUtil.setRedisTemplate(redisTemplate);        return redisUtil;    }

四．编写RedisUtil消息发布方法

public class RedisUtils {    private static final Logger log = LoggerFactory.getLogger(RedisUtils.class);    private RedisTemplate redisTemplate;    public void setRedisTemplate(RedisTemplate redisTemplate) {        this.redisTemplate = redisTemplate;    }    public void publish(String channal ,Object obj) {        redisTemplate.convertAndSend(channal,obj );    }}

五．配置消息监听

@Configurationpublic class RedisMessageListener {    /**     * 创建连接工厂     * @param connectionFactory     * @param listenerAdapter     * @return     */    @Bean    public RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,                                                   MessageListenerAdapter listenerAdapter,MessageListenerAdapter listenerAdapter2){        RedisMessageListenerContainer container = new RedisMessageListenerContainer();        container.setConnectionFactory(connectionFactory);        //接受消息的key        container.addMessageListener(listenerAdapter,new PatternTopic("phone"));        return container;    }    /**     * 绑定消息监听者和接收监听的方法     * @param receiver     * @return     */    @Bean    public MessageListenerAdapter listenerAdapter(ReceiverRedisMessage  receiver){        return new MessageListenerAdapter(receiver,"receiveMessage");    }    /**     * 注册订阅者     * @param latch     * @return     */    @Bean    ReceiverRedisMessage receiver(CountDownLatch latch) {        return new ReceiverRedisMessage(latch);    }    /**     * 计数器，用来控制线程     * @return     */    @Bean    public CountDownLatch latch(){        return new CountDownLatch(1);//指定了计数的次数 1    }}

六．消息订阅方法

public class ReceiverRedisMessage {    private static final Logger log = LoggerFactory.getLogger(ReceiverRedisMessage.class);    private CountDownLatch latch;    @Autowired    public ReceiverRedisMessage(CountDownLatch latch) {        this.latch = latch;    }    /**     * 队列消息接收方法     *     * @param jsonMsg     */    public void receiveMessage(String jsonMsg) {        log.info("[开始消费REDIS消息队列phone数据...]");        try {            log.info("监听者收到消息：{}", jsonMsg);            JSONObject exJson = JSONObject.parseObject(jsonMsg);            User user = JSON.toJavaObject(exJson, User.class);            System.out.println("转化为对象 ："+user);            log.info("[消费REDIS消息队列phone数据成功.]");        } catch (Exception e) {            log.error("[消费REDIS消息队列phone数据失败，失败信息:{}]", e.getMessage());        }        latch.countDown();    }}

七．定时消息发布测试

@EnableScheduling@Componentpublic class PublisherController {    private static final Logger log = LoggerFactory.getLogger(PublisherController.class);    @Autowired    private RedisUtils redisUtils;    @Scheduled(fixedRate = 5000)    public String pubMsg() {        User user=new User(1, "尚***", 26,"男","陕西省xxxx市xxxxxx县");        redisUtils.publish("phone", user);        log.info("Publisher sendes Topic... ");        return "success";    }}

八．测试结果

九．发布对象User实体

 public class User implements Serializable {    /**     *      */    private static final long serialVersionUID = 1L;    private int id;    private String name;    private int age;    private String sex;    private String address;     .....................}
