SpringBoot框架中redis序列化

在SpringBoot框架中进行redis访问的时候，发现写入redis中的数据产生了乱码，是因为没有对对象数据进行序列化，此时需要编写一个序列化配置类，在启动的时候注入Spring容器，默认使用该类对对象进行序列化后进行存储：

1、创建一个redis配置类

2、添加redis相关依赖：

  <!--redis链接-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>

3、编写序列化类

package com.example.demowj.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import javax.annotation.Resource;

public class RedisConfig {
    @Resource
    private RedisTemplate redisTemplate;

    @Bean
    public RedisTemplate<String, Object> setSerializer() {
        LettuceConnectionFactory jedisConnectionFactory = (LettuceConnectionFactory) redisTemplate.getConnectionFactory();
        redisTemplate.setConnectionFactory(jedisConnectionFactory);
        Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper mapper = new ObjectMapper();
        mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        serializer.setObjectMapper(mapper);
        //使用StringRedisSerializer来序列化和反序列化redis的key值
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(serializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        redisTemplate.setEnableTransactionSupport(true);
        return redisTemplate;
    }
}
