java获得redis所有的key-value

运行结果：

 

redis配置文件需要序列化：

  @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        StringRedisSerializer serializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(serializer);
        redisTemplate.setValueSerializer(serializer);
        return redisTemplate;
    }
