Configuration class :( implement serialization of redis)

package com.example.mypay.config;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

import java.nio.charset.Charset;

public class FastJsonRedisSerializer<T> implements RedisSerializer<T> {

    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

    private Class<T> clazz;

    public FastJsonRedisSerializer(Class<T> clazz) {
        super();
        this.clazz = clazz;
    }

    @Override
    public byte[] serialize(T t) throws SerializationException {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
    }

    @Override
    public T deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length <= 0) {
            return null;
        }
        String str = new String(bytes, DEFAULT_CHARSET);
        return (T) JSON.parseObject(str, clazz);
    }

}

Configuration class:

package com.example.mypay.config;


import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.parser.ParserConfig;
import com.alibaba.fastjson.support.config.FastJsonConfig;

import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.context.annotation.Bean;
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.StringRedisSerializer;

@Configuration
public class RedisConfig {
    RedisConfig(){
        //打开autotype功能,需要强转的类一次添加其后
        ParserConfig.getGlobalInstance()
                .addAccept("com.example.mypay.entity");
    }

    @Bean
    public RedisTemplate<Object,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<Object,Object> template =new RedisTemplate<>();
        //template .setConnectionFactory(redisConnectionFactory);
        FastJsonRedisSerializer<Object> fastJsonRedisSerializer=new FastJsonRedisSerializer<>(Object.class);
        template.setValueSerializer(fastJsonRedisSerializer);
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashValueSerializer(fastJsonRedisSerializer);
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setConnectionFactory(redisConnectionFactory);
            return template;

    }

  
}

  Objects can be directly taken

redis data patterns
