使用redis经验，记录一下，区别于老版本的redis配置。
一、首先是redis的配置文件
此处的配置区别于2.x版本以下的配置。

@Configuration
public class RedisConfiguration {
@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
RedisSerializer stringRedisSerializer = new StringRedisSerializer();
template.setKeySerializer(stringRedisSerializer);

redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setConnectionFactory(redisConnectionFactory);
return redisTemplate;
}
}
二、开始使用
以下是使用保存字符串类型
1
stringRedisTemplate.opsForValue().set("hashset: keyName", data, 12, TimeUnit.HOURS);
以上是使用hashset作为头, 所有的数据全部放在头下面, data就是要存储的字符串, 12是过期的时间
1
String redisResult = stringRedisTemplate.opsForValue().get("hashset: keyName");
以上是取值
