问题描述

List<List> 类型数据parseObject时报错

环境信息

• JDK信息： [e.g.：Openjdk 1.8.0_312]
• 版本信息：[e.g.：Fastjson2 2.0.26]

重现步骤

import java.util.List;

public class Test {

public static void main(String[] args) {
    String s = "{\"values\":[[123,456]]}";

    Data data1 = com.alibaba.fastjson.JSON.parseObject(s, Data.class);
    System.out.println("fastjson data:" + com.alibaba.fastjson.JSON.toJSONString(data1));

    Data data2 = com.alibaba.fastjson2.JSON.parseObject(s, Data.class);
    System.out.println("fastjson2 data:" + com.alibaba.fastjson2.JSON.toJSONString(data2));
}

public static class Data {

    private List<List<Object>> values;

    public List<List<Object>> getValues() {
        return values;
    }

    public void setValues(List<List<Object>> values) {
        this.values = values;
    }
}

}

期待的正确结果

内层List中数据类型不定，期望能正常解析
