默认的FastJson2 序列化存在问题

默认的序列化不能转换List 中的泛型数据类型, 从缓存拿取的list集合对象数据全部都转换成了JSONObject

增强FastJson 支持

Encode 编码器

增加JSON对象类型存储

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONWriter;
import com.alicp.jetcache.support.Fastjson2ValueEncoder;

/**
 * @author wangke
 * @version 1.0
 * @description:
 * @date 2024/4/19 9:43
 */
public class JetCacheFastjson2ValueEncoder extends Fastjson2ValueEncoder {

    public JetCacheFastjson2ValueEncoder(boolean useIdentityNumber) {
        super(useIdentityNumber);
    }

    @Override
    public byte[] apply(Object value) {
        return super.apply(value);
    }

    @Override
    protected byte[] encodeSingleValue(Object value) {
    	// 保存JSON数据对象类型
        return JSON.toJSONString(value, JSONWriter.Feature.WriteClassName).getBytes();
    }
}

Decode 解码器

增加JSON对象类型解析

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONReader;
import com.alicp.jetcache.support.Fastjson2ValueDecoder;

import java.nio.charset.StandardCharsets;

/**
 * @author wangke
 * @version 1.0
 * @description:
 * @date 2024/4/19 10:13
 */
public class JetCacheFastjson2ValueDecoder extends Fastjson2ValueDecoder {

    public static final JetCacheFastjson2ValueDecoder INSTANCE = new JetCacheFastjson2ValueDecoder(true);

    public JetCacheFastjson2ValueDecoder(boolean useIdentityNumber) {
        super(useIdentityNumber);
    }

    @Override
    protected Object parseObject(byte[] buffer, int index, int len, Class clazz) {
        String s = new String(buffer, index, len, StandardCharsets.UTF_8);
    	// 解析 JSON数据对象类型
        return JSON.parseObject(s, clazz, JSONReader.Feature.SupportAutoType);
    }
}
