Redis序列化问题

环境：spring boot、RedisTemplate

将key和value存入Redis，并进行查看时发现

查询了相关文章了解到序列化问题，记录一下

package com.spring;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
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.StringRedisSerializer;

@SpringBootApplication
public class SpringbootApplication extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(SpringbootApplication.class, args);
	}

	/**
	 * redisTemplate 序列化使用的jdkSerializeable, 存储二进制字节码, 所以自定义序列化类
	 * @param redisConnectionFactory
	 * @return
	 */
	@Bean
	public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
		RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
		redisTemplate.setConnectionFactory(redisConnectionFactory);

		// 使用Jackson2JsonRedisSerialize 替换默认序列化
		Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

		ObjectMapper objectMapper = new ObjectMapper();
		objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
		objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

		jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

		// 设置value的序列化规则和 key的序列化规则
		redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
		redisTemplate.setKeySerializer(new StringRedisSerializer());
		redisTemplate.afterPropertiesSet();
		return redisTemplate;
	}
}

在spring boot的启动类中添加以上代码即可
