解决Redis序列化乱码问题

如果我们使用原生的JDK序列化，那么当我们将数据存储到Redis中就会出现乱码的情况

为了解决这个问题我们需要重写RedisTemplate从而解决序列化乱码问题

首先在Maven中引入相应的依赖

               
            com.fasterxml.jackson.core
            jackson-core
            2.12.7
        
        
            com.fasterxml.jackson.core
            jackson-databind
            2.12.7
        

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
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 RedisConfig {

    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        RedisSerializer redisSerializer = new StringRedisSerializer();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(redisSerializer);
        redisTemplate.setHashKeySerializer(redisSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer());
        return redisTemplate;
    }

    private Jackson2JsonRedisSerializer
