application.yml

spring:
  ...
  redis:
    host: 127.0.0.1
    port: 6379
    database: 0  #Redis使用的数据库
    timeout: 18000   #连接超时事件毫秒
    lettuce:
      pool:
        max-active: 20   #连接池最大连接数
        max-idle: 5   #最大阻塞等待时间
        min-idle: 0  #连接池最小空闲连接

RedisConfig.java

    @Bean
    public RedisTemplate<String,Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory){
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        //设置key序列化方式String
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //设置value的序列化方式json，使用GenericJackson2JsonRedisSerializer替换默认的序列化
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

TestController.java

@RestController
public class TestController {
    
    ...
    @Autowired
    RedisTemplate redisTemplate;

    ...
    @RequestMapping(value = "/test/getRedisValue", method = RequestMethod.GET)
    public Object getRedisValue(){
        redisTemplate.opsForValue().set("name", "seven");
        Object obj = redisTemplate.opsForValue().get("name");
        return obj;
    }

}
