RedisTemplate 拿不到数据的问题

问题描述:
redisTemplate.opsForValue().get()
拿任何一个值都是空,但是在redisDeskManager却都可以查的到, debug看了RedisTemplate 中的连接信息,发现确实是连接同一个db

结果发现是序列化的问题, 下面出我抄袭的redis配置代码

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisTemplateSerializer {

    RedisTemplate redisTemplate;

    @Autowired
    public void setRedisTemplate(RedisTemplate redisTemplate) {
        // 序列化为String
        RedisSerializer stringSerializer = new StringRedisSerializer();
        //序列化为Json
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);        redisTemplate.setKeySerializer(stringSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(stringSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        this.redisTemplate = redisTemplate;
    }
}

一开始我只是把key做了StringRedisSerializer,但在查询的时候还是拿不到redis里面的数据
后来发现必须要把, key value都序列化才可以查得到
