redis如何實現序列化

Redis提供了兩個模板類RedisTemplate和StringRedisTemplate實現序列化，如：

1.RedisAutoConfiguration源碼，對key和value進行序列化：

public class RedisAutoConfiguration {
public RedisAutoConfiguration() {
}
@Bean
@ConditionalOnMissingBean(
name = {"redisTemplate"}
)
//RedisTemplate的key和value都是Object類型的，如果進行網絡傳輸或將數據存儲到硬盤上就需對key和value進行序列化
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;
}
}

2.StringRedisTemplate源碼，將key和value都序列化為String類型的：

//StringRedisTemplate類繼承RedisTemplate
public class StringRedisTemplate extends RedisTemplate {
//將key和value都序列化為String類型的，也是只支持String類型的key和value
public StringRedisTemplate() {
this.setKeySerializer(RedisSerializer.string());
this.setValueSerializer(RedisSerializer.string());
this.setHashKeySerializer(RedisSerializer.string());
this.setHashValueSerializer(RedisSerializer.string());
}
}
