这是我的代码：

try {
  DeleteObjectsResult delObjRes = s3Client
      .deleteObjects(multiObjectDeleteRequest);
  System.out.format("Successfully deleted all the %s items.\n", delObjRes
      .getDeletedObjects().size());

} catch (MultiObjectDeleteException e) {
  System.out.format("%s \n", e.getMessage());
  System.out.format("No. of objects successfully deleted = %s\n", e
      .getDeletedObjects().size());
  System.out.format("No. of objects failed to delete = %s\n", e.getErrors()
      .size());
  System.out.format("Printing error data...\n");
  for (DeleteError deleteError : e.getErrors()) {
    System.out.format("Object Key: %s\t%s\t%s\n", deleteError.getKey(),
        deleteError.getCode(), deleteError.getMessage());
  }
}

例外情况如下：

Exception in thread "main" Status Code: 400, AWS Service: Amazon S3, AWS Request ID: 3EB96BFE84959731, AWS Error Code: MalformedXML, …

我有一个A类

public  abstract class A extends RealmObject{

}

public class B extends A {

}

错误：必须从 RealmObject 派生一个 RealmClass 注释对象
