一．創(chuàng)建spring boot項(xiàng)目
dependency>
groupId>org.springframework.boot/groupId>
artifactId>spring-boot-starter-data-redis/artifactId>
/dependency>
dependency>
groupId>org.springframework.boot/groupId>
artifactId>spring-boot-starter-web/artifactId>
/dependency>
dependency>
groupId>com.alibaba/groupId>
artifactId>fastjson/artifactId>
version>1.2.41/version>
/dependency>
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: error
spring:
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
@Configuration
public class RedisConfiguration {
/**
* 實(shí)例化 RedisTemplate 對(duì)象
*
* @return
*/
@Bean("RedisTemplateS")
public RedisTemplateString, Object> functionDomainRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplateString, Object> redisTemplate = new RedisTemplate>();
initDomainRedisTemplate(redisTemplate, redisConnectionFactory);
return redisTemplate;
}
/**
* 設(shè)置數(shù)據(jù)存入 redis 的序列化方式,并開啟事務(wù)
*
* @param redisTemplate
* @param factory
*/
private void initDomainRedisTemplate(@Qualifier("RedisTemplateS") RedisTemplateString, Object> redisTemplate, RedisConnectionFactory factory) {
// 如果不配置Serializer，那么存儲(chǔ)的時(shí)候缺省使用String，如果用User類型存儲(chǔ)，那么會(huì)提示錯(cuò)誤User can't cast to
// String！
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
FastJsonRedisSerializerObject> fastJsonRedisSerializer = new FastJsonRedisSerializerObject>(Object.class);
redisTemplate.setHashValueSerializer(fastJsonRedisSerializer);
redisTemplate.setValueSerializer(fastJsonRedisSerializer);
//redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
//redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
// 開啟事務(wù)
redisTemplate.setEnableTransactionSupport(true);
redisTemplate.setConnectionFactory(factory);
}
/**
* 注入封裝RedisTemplate @Title: redisUtil @return RedisUtil @date
*
*/
@Bean(name = "redisUtils")
public RedisUtils redisUtil(@Qualifier("RedisTemplateS") RedisTemplateString, Object> redisTemplate) {
RedisUtils redisUtil = new RedisUtils();
redisUtil.setRedisTemplate(redisTemplate);
return redisUtil;
}
四．編寫RedisUtil消息發(fā)布方法
public class RedisUtils {
private static final Logger log = LoggerFactory.getLogger(RedisUtils.class);
private RedisTemplateString, Object> redisTemplate;
public void setRedisTemplate(RedisTemplateString, Object> redisTemplate) {
this.redisTemplate = redisTemplate;
}
public void publish(String channal ,Object obj) {
redisTemplate.convertAndSend(channal,obj );
}
}
五．配置消息監(jiān)聽
@Configuration
public class RedisMessageListener {
/**
* 創(chuàng)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(jiān)聽者和接收監(jiān)聽的方法
* @param receiver
* @return
*/
@Bean
public MessageListenerAdapter listenerAdapter(ReceiverRedisMessage receiver){
return new MessageListenerAdapter(receiver,"receiveMessage");
}
/**
* 注冊(cè)訂閱者
* @param latch
* @return
*/
@Bean
ReceiverRedisMessage receiver(CountDownLatch latch) {
return new ReceiverRedisMessage(latch);
}
/**
* 計(jì)數(shù)器，用來控制線程
* @return
*/
@Bean
public CountDownLatch latch(){
return new CountDownLatch(1);//指定了計(jì)數(shù)的次數(shù) 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(duì)列消息接收方法
*
* @param jsonMsg
*/
public void receiveMessage(String jsonMsg) {
log.info("[開始消費(fèi)REDIS消息隊(duì)列phone數(shù)據(jù)...]");
try {
log.info("監(jiān)聽者收到消息：{}", jsonMsg);
JSONObject exJson = JSONObject.parseObject(jsonMsg);
User user = JSON.toJavaObject(exJson, User.class);
System.out.println("轉(zhuǎn)化為對(duì)象 ："+user);
log.info("[消費(fèi)REDIS消息隊(duì)列phone數(shù)據(jù)成功.]");
} catch (Exception e) {
log.error("[消費(fèi)REDIS消息隊(duì)列phone數(shù)據(jù)失敗，失敗信息:{}]", e.getMessage());
}
latch.countDown();
}
}
七．定時(shí)消息發(fā)布測(cè)試
@EnableScheduling
@Component
public 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(cè)試結(jié)果
九．發(fā)布對(duì)象User實(shí)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;
.....................
}
