Redis默认序列化方式乱码原因及解决办法

乱码原因

使用自定义序列化器

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
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;@Configuration
public class RedisConfig {@Beanpublic Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer(){Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(objectMapper);return jackson2JsonRedisSerializer;}@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, Object> template = new RedisTemplate<>();// Key HashKey使用String序列化template.setKeySerializer(RedisSerializer.string());template.setHashKeySerializer(RedisSerializer.string());// Value HashValue使用Jackson2JsonRedisSerializer序列化template.setValueSerializer(jackson2JsonRedisSerializer());template.setHashValueSerializer(jackson2JsonRedisSerializer());template.setConnectionFactory(factory);return template;}
