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
<dependency> <groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.12.7</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.12.7</version></dependency>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 {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();RedisSerializer<String> redisSerializer = new StringRedisSerializer();redisTemplate.setConnectionFactory(redisConnectionFactory);redisTemplate.setKeySerializer(redisSerializer);redisTemplate.setHashKeySerializer(redisSerializer);redisTemplate.setValueSerializer(jackson2JsonRedisSerializer());redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer());return redisTemplate;}private Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer() {Jackson2JsonRedisSerializer<Object> jsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);jsonRedisSerializer.setObjectMapper(objectMapper);return jsonRedisSerializer;}}添加完这个配置类以后再使用RedisTemplate将数据序列化到Redis中就不会出现乱码的情况了
