redis-springboot-redistemplate更改序列化方式

redisTemplate 默认的序列化方式为 jdkSerializeable, StringRedisTemplate的默认序列化方式为StringRedisSerializer

可以通过手动配置, 将redisTemplate的序列化方式进行更改

package com.wenbronk.data.redis;

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.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 RedisApplication {

    public static void main(String[] args) {

        SpringApplication.run(RedisApplication.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

     */

    @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;

    }

}
