rebuild一下项目就好了,我没法复现...

只能简单试了一下,好像没啥问题
以下是测试代码:

public static void main(String[] args) throws IOException {
  Bean bean = new Bean();
  byte[] bytes = JSONB.toBytes(bean, JSONWriter.Feature.WriteClassName,
          JSONWriter.Feature.FieldBased,
          JSONWriter.Feature.ReferenceDetection,
          JSONWriter.Feature.WriteNulls,
          JSONWriter.Feature.NotWriteDefaultValue,
          JSONWriter.Feature.NotWriteHashMapArrayListClassName,
          JSONWriter.Feature.WriteNameAsSymbol);

  System.out.println(Objects.nonNull(bytes));

  Bean bean1 = JSONB.parseObject(bytes, Bean.class,
          JSONReader.Feature.UseDefaultConstructorAsPossible,
          JSONReader.Feature.UseNativeObject,
          JSONReader.Feature.IgnoreAutoTypeNotMatch,
          JSONReader.Feature.FieldBased);

  System.out.println(bean1.lock);
}

public static class Bean {
  public Lock lock = new ReentrantLock();
}

如果lock是外部传入的话,序列化再反序列化,lock就没了,算不算问题?

public static void main(String[] args) throws IOException {
    Bean bean = new Bean();
    bean.lock = new ReentrantLock();
    bean.lock.lock();
    byte[] bytes = JSONB.toBytes(bean, JSONWriter.Feature.WriteClassName,
            JSONWriter.Feature.FieldBased,
            JSONWriter.Feature.ReferenceDetection,
            JSONWriter.Feature.WriteNulls,
            JSONWriter.Feature.NotWriteDefaultValue,
            JSONWriter.Feature.NotWriteHashMapArrayListClassName,
            JSONWriter.Feature.WriteNameAsSymbol);
    System.out.println(Objects.nonNull(bytes));
    Bean bean1 = JSONB.parseObject(bytes, Bean.class,
            JSONReader.Feature.UseDefaultConstructorAsPossible,
            JSONReader.Feature.UseNativeObject,
            JSONReader.Feature.IgnoreAutoTypeNotMatch,
            JSONReader.Feature.FieldBased);
    System.out.println(bean1.lock);
}

public static class Bean {
    public Lock lock;
}

测试结果:

true
