本文档展示了如何为Spring Boot应用配置一个自定义的RedisTemplate，特别是针对<String, Object>类型的键值对，使用Jackson2JsonRedisSerializer进行JSON序列化，并通过StringRedisSerializer处理字符串键。配置包括设置key和hash key的序列化方式以及value和hash value的序列化策略。

分享一个RedisTemplate自定义序列化配置

主要针对于<String, Object>的，其他情况可以做参考用

package com.example.demo.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Conditional;
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.StringRedisSerializer;
import org.springframework.web.client.RestTemplate;

@Configuration
public class Config {
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate redisTemplate (RedisConnectionFactory factory){
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);
        //JSON解析任意对象
        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);
        //String 的序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        //key采用String方式序列化
        template.setKeySerializer(stringRedisSerializer);
        template.setHashKeySerializer(stringRedisSerializer);
        //value采用 Jackson方式序列化
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        return template;
    }
}
