SpringBoot整合Redis数据库

Redis对象序列化操作：

package com.example.zcw.redis;

import org.springframework.core.convert.converter.Converter;
import org.springframework.core.serializer.support.DeserializingConverter;
import org.springframework.core.serializer.support.SerializingConverter;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

public class RedisObjectSerializer implements RedisSerializer<Object> {
    //为了进行对象与字节数组的转换，应准备两个转换器
    private Converter<Object,byte[]> serializingConverter = new SerializingConverter();
    private Converter<byte[],Object> deserializingConverter = new DeserializingConverter();
    private static final byte[] EMPTY_BYTE_ARRAY = new byte[0];//做一个空数组，不是null

    @Override
    public byte[] serialize(Object obj)throws SerializationException {
        if(obj== null){
            //如果没有要序列化的对象，则返回一个空数组
            return EMPTY_BYTE_ARRAY;
        }
        return this.serializingConverter.convert(obj);//将对象变为字节数组
    }

    @Override
    public Object deserialize(byte[] data)throws SerializationException{
        if(data ==null || data.length ==0){
            //如果没有对象内容信息
            return null;
        }
        return this.deserializingConverter.convert(data);
    }
}

创建RedisTemplate模板的配置类
