一．創建spring boot項目

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

二．編輯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 { /** * 實例化 RedisTemplate 對象 * * @return */ @Bean("RedisTemplateS") public RedisTemplate functionDomainRedisTemplate(RedisConnectionFactory redisConnectionFactory) { RedisTemplate redisTemplate = new RedisTemplate<>(); initDomainRedisTemplate(redisTemplate, redisConnectionFactory); return redisTemplate; } /** * 設置數據存入 redis 的序列化方式,并開啟事務 * * @param redisTemplate * @param factory */ private void initDomainRedisTemplate(@Qualifier("RedisTemplateS") RedisTemplate redisTemplate, RedisConnectionFactory factory) { // 如果不配置Serializer，那么存儲的時候缺省使用String，如果用User類型存儲，那么會提示錯誤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()); // 開啟事務 redisTemplate.setEnableTransactionSupport(true); redisTemplate.setConnectionFactory(factory); } /** * 注入封裝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．編寫RedisUtil消息發布方法

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．配置消息監聽

@Configurationpublic class RedisMessageListener { /** * 創建連接工廠 * @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; } /** * 綁定消息監聽者和接收監聽的方法 * @param receiver * @return */ @Bean public MessageListenerAdapter listenerAdapter(ReceiverRedisMessage receiver){ return new MessageListenerAdapter(receiver,"receiveMessage"); } /** * 注冊訂閱者 * @param latch * @return */ @Bean ReceiverRedisMessage receiver(CountDownLatch latch) { return new ReceiverRedisMessage(latch); } /** * 計數器，用來控制線程 * @return */ @Bean public CountDownLatch latch(){ return new CountDownLatch(1);//指定了計數的次數 1 }}

六．消息訂閱方法

public class ReceiverRedisMessage { private static final Logger log = LoggerFactory.getLogger(ReceiverRedisMessage.class); private CountDownLatch latch; @Autowired public ReceiverRedisMessage(CountDownLatch latch) { this.latch = latch; } /** * 隊列消息接收方法 * * @param jsonMsg */ public void receiveMessage(String jsonMsg) { log.info("[開始消費REDIS消息隊列phone數據...]"); try { log.info("監聽者收到消息：{}", jsonMsg); JSONObject exJson = JSONObject.parseObject(jsonMsg); User user = JSON.toJavaObject(exJson, User.class); System.out.println("轉化為對象 ："+user); log.info("[消費REDIS消息隊列phone數據成功.]"); } catch (Exception e) { log.error("[消費REDIS消息隊列phone數據失敗，失敗信息:{}]", e.getMessage()); } latch.countDown(); }}

七．定時消息發布測試

@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","陜西省xxxx市xxxxxx縣"); redisUtils.publish("phone", user); log.info("Publisher sendes Topic... "); return "success"; }}

八．測試結果

九．發布對象User實體

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; .....................}
