redis如何实现序列化

Redis提供了两个模板类RedisTemplate和StringRedisTemplate实现序列化，如：

RedisAutoConfiguration源码，对key和value进行序列化：

public class RedisAutoConfiguration {
public RedisAutoConfiguration() {
}
@Bean
@ConditionalOnMissingBean(
name = {"redisTemplate"}
)
//RedisTemplate的key和value都是Object类型的，如果进行网络传输或将数据存储到硬盘上就需对key和value进行序列化
public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
RedisTemplate template = new RedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
@Bean
@ConditionalOnMissingBean
public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
StringRedisTemplate template = new StringRedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
}

StringRedisTemplate源码，将key和value都序列化为String类型的：

//StringRedisTemplate类继承RedisTemplate
public class StringRedisTemplate extends RedisTemplate {
//将key和value都序列化为String类型的，也是只支持String类型的key和value
public StringRedisTemplate() {
this.setKeySerializer(RedisSerializer.string());
this.setValueSerializer(RedisSerializer.string());
this.setHashKeySerializer(RedisSerializer.string());
this.setHashValueSerializer(RedisSerializer.string());
}
}
