Hibernate DefaultEntityAliases引发NullPointerException（null pointer in method invocation）

我正在使用Spring Boot，Spring Data REST，Hibernate（5.2.12.Final），并将存储库公开为REST服务。

我有一个引发NullPointerException的查询问题，我不明白原因。我正在通过HTTP请求调用此方法（Spring Data
REST公开了此方法）。

这是代码：

@Transactional(readOnly = true)@PreAuthorize("isAuthenticated()")public interface CheckPointRepository extends JpaRepository<CheckPoint, Long> {@Query(value = "SELECT * FROM CheckPoint WHERE (:name IS NULL OR name LIKE CONCAT(''%'',:name,''%'')) ORDER BY name LIMIT 20", nativeQuery = true)    public List<CheckPoint> findByNameOrderByNameList(@Param("name") String name);}

这是堆栈跟踪：

我确实没有发现该查询有任何问题。我是在做错什么还是错误？

=====================其他和最终信息=====================

经过多次尝试，我了解到问题不是我的查询，而是我对实体具有的几个公式CheckPoint：

@Entitypublic class CheckPoint extends AbstractEntity {    private static final long serialVersionUID = 2719798641638659883L;    @Audited    @NotBlank    @Column(nullable = false, unique = true)    private String name;    private LocalTime openingTime;    private LocalTime closingTime;    // The minimum number of ticket that should be present in the checkpoint    @Audited    @Min(value = 0)    @Column(nullable = false)    private int stockThreshold = 0;    // Available blocks in this checkpoint    @Formula(value = "(SELECT COUNT(*) FROM TicketBlock t WHERE t.CheckPoint_id=id)")    private long availableBlocks;    @Formula(value = "(SELECT COALESCE(SUM(t.availableTickets),0) FROM TicketBlock t WHERE t.CheckPoint_id=id)")    private long availableTickets;

结合Repository中的任何本地查询，都会抛出该Exception（也是一个简单的"FROMCheckPoint"）。我解决了在存储库中进行HQL查询而不是本机查询的问题。当然，这并不是我想要的，我认为这是一种解决方法。我认为NullPointerException始终是一个错误。想知道是否有人比我更能为该主题添加有用的信息。

答案1

是的，有一个针对此确切情况的带缺陷@Formula注释的错误报告，并且nativeQuery…您可以添加5.2作为受影响的版本，因为它仅报告为5.1

android – 调用相机意图后onActivityResult中的NullPointerException

这是我的问题：我需要将照片保存到默认的相机位置,而不是将照片复制到我的私人位置,添加GPS标签进行复制,以及删除原始照片.为何如此？因为在某些设备上,当在请求中使用MediaStore.EXTRA_OUTPUT时,照片无论如何都保存在默认位置.现在,当应用程序接近完成时,在新设备(摩托罗拉MB526)上进行测试时,它会在接受拍摄照片后崩溃.同样的事情发生在模拟器上.

问题是,在onActivityResult(int requestCode,int resultCode,Intent data)中,data.getData()返回null.

所以我的问题是 – 有没有统一的方法来保存给定位置和其他地方的图片？

编辑：

捕获图像意图

protected void takePhotos() {
    Intent imageIntent = new Intent(
            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(imageIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}

和结果

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
            if (resultCode == RESULT_OK && data != null) {
                Uri capturedImageUri = data.getData();
                Log.d("cameraResult", "data =" + data.getDataString());
                String capturedPicFilePath = getRealPathFromURI(capturedImageUri);
                writeImageData(capturedImageUri, capturedPicFilePath);
            } else if (resultCode == RESULT_CANCELED) {
                Toast.makeText(this, "Picture not taken",
                        Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(this, "Picture not taken",
                        Toast.LENGTH_SHORT).show();
            }
        }
    }
}

public String getRealPathFromURI(Uri contentUri) {
    String[] projx = { MediaStore.Images.Media.DATA };
    Cursor cursor;
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.GINGERBREAD_MR1) {
        CursorLoader loader = new CursorLoader(this, contentUri, projx,
                null, null, null);
        cursor = loader.loadInBackground();
    } else {
        cursor = this.managedQuery(contentUri, projx, null, null, null);
    }
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.movetoFirst();
    return cursor.getString(column_index);
}

这可能是错的,但我在ACTION_IMAGE_CAPTURE之后做了这个以获得uri,它对我有用.

        Bitmap picture = (Bitmap) data.getExtras().get("data");
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        picture.compress(Bitmap.CompressFormat.JPEG, 100, stream);

        String path = Images.Media.insertimage(getContentResolver(), picture,
                "title" , null);
        Uri uriPhoto = Uri.parse(path);
