保存到redis中的token乱码了

示图：

原因是缓存保存到redis需要序列化操作，没有序列化会出现这样的问题

序列化redis第一步：

package com.abliner.test.configure.redis;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
import com.abliner.test.common.service.RedisService;
import com.abliner.test.common.service.impl.RedisServiceImpl;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheWriter;
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.RedisSerializationContext;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.time.Duration;

@Configuration
public class BaseRedisConfig {
    @ConditionalOnMissingBean(RedisTemplate.class)
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisSerializer<Object> serializer = redisSerializer();
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(serializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(serializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    @Bean
    @ConditionalOnMissingBean(RedisSerializer.class)
    public RedisSerializer<Object> redisSerializer() {
        //创建JSON序列化器
        Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //必须设置，否则无法将JSON转化为对象，会转化成Map类型
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL);
        serializer.setObjectMapper(objectMapper);
        return serializer;
    }

    /**
     * 支持缓存层
     * @nice-support springboot.cache.cacheLayer
     * @nice-use
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    @ConditionalOnMissingBean(RedisCacheManager.class)
    public RedisCacheManager redisCacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory);
        //设置Redis缓存有效期为1天
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer())).entryTtl(Duration.ofDays(1));
        return new RedisCacheManager(redisCacheWriter, redisCacheConfiguration);
    }

    @Bean
    @ConditionalOnMissingBean(RedisService.class)
    public RedisService redisService(){
        return new RedisServiceImpl();
    }
}

序列化redis第二步：

package com.abliner.test.configure.redis;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisTemplateBeanPostProcessor implements BeanPostProcessor {

    @Override
    public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
        if (RedisTemplate.class.isAssignableFrom(bean.getClass())) {
            RedisTemplate redisTemplate = (RedisTemplate) bean;
            // StringRedisSerializer：常用来序列化Key，也可以用来序列化Value。
            StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
            redisTemplate.setKeySerializer(stringRedisSerializer);
            redisTemplate.setValueSerializer(stringRedisSerializer);
        }
        return bean;
    }

}

重新保存新的数据重新载入redis数据。如图：

这样生成出来的可以就不会乱码了。
