在java中删除Amazon s3中的对象列表

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, AWS Error Message: The XML you provided was not well-formed or did not validate against our published schema, S3 Extended Request ID: pE+pEHF36KqItpx1y6tJe6m50lTD1C/YHe0bVOmJW5TRBV7EfxvS5+Dc6JKX5AYb

最佳答案 当List< KeyVersion>时,我看到了这个服务异常.我在DeleteObjectsRequest对象上设置(通过setKeys方法)是空的.查看您在上述评论中发布的代码,这可能是您遇到问题的原因：

List<KeyVersion> keys = new ArrayList<KeyVersion>();
for (String keyName : listOfNames) {
  if (keyName != null && !keyName.isEmpty()) keys.add(new KeyVersion(keyName));
}

/ *键列表在这里可能是空的！ * /

multiObjectDeleteRequest.setKeys(keys);
