问题描述

fastjson 2.0.27-SNAPSHOT版本调用JSON.toJSONString() 方法时，产生npe

环境信息

重现步骤

1、分别定义2个类（一点要是公共类）

@Data
public class Aa {
    private List<Bb> bList;
}

@Data
public class Bb {
    private List<LocalDateTime> dateTimes;
}

2、执行测试用例

 @Test
    public void t2(){
        Aa a =new Aa();
        List<Bb> bList = new ArrayList<>();
        Bb b1 = new Bb();
        bList.add(b1);
        Bb b2 = new Bb();
        bList.add(b2);
        List<LocalDateTime> dateTimes1 = new ArrayList<>();
        dateTimes1.add(LocalDateTime.now());
        dateTimes1.add(LocalDateTime.now());
        b1.setDateTimes(dateTimes1);


        List<LocalDateTime> dateTimes2 = new ArrayList<>();
        dateTimes2.add(LocalDateTime.now());
//        dateTimes2.add(LocalDateTime.now());
        b2.setDateTimes(dateTimes2);
        a.setBList(bList);
        Map<String, Object> map2 = ReflectUtils.buildObjectForMap(a);
        String json = JSON.toJSONString(map2);
        System.out.println(json);
    }

出现空指针异常
