配置Redis

spring:
  redis:
    sentinel:
      master: mymaster
      nodes:
        - 192.168.44.142:26379
        - 192.168.44.146:26379
    lettuce:
      pool:
        ### 最大连接数（使用负值表示没有限制） 默认8
        max-active: 8
        ### 最小空闲连接  默认8
        min-idle: 0
        ### 连接池中的最大空闲连接 默认8
        max-idle: 8
        ### 连接池最大阻塞等待时间（使用负值表示没有限制）
        max-wait: -1ms
    ### 连接超时时间（毫秒）
    timeout: 60000ms
    password: 123456

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

@Component
public final class RedisUtil {

    @Autowired

测试类

@Autowired
private RedisUtil redisUtil;



while(true){
    Thread.sleep(1011);
    redisUtil.set("time", DateUtils.getCurrentTimeStr());
    System.out.println(redisUtil.get("time"));
}
