Question

我看到了一些关于此错误的问题，但我无法找到解决方案。

我在spring boot应用程序中实现了分页。

我在我的控制器中有这个方法

@RequestMapping(method = RequestMethod.GET, value = "/distrito",  params = { "page", "size" })
    public ResponseEntity<Page<Distritos>> buscarTodosDistritos(HttpServletRequest request, @RequestParam("page") int page, @RequestParam("size") int size) throws ServletException { 
        Map<String, String>informacaoUsuario = uService.getInformacoesUsuario(request);

        Page<Distritos> distritosBuscados = distritosService.buscarFiltro(Long.parseLong(informacaoUsuario.get("idEntidadeSelecionada")), page, size);
            return new ResponseEntity<>(distritosBuscados, HttpStatus.OK);
    }

和我的服务

    public Page<Distritos> buscarFiltro(Long usuarioEntidade ,int size, int page){
        return distritosRepository.encontrar(usuarioEntidade, size, page);
    }

我的资料库

@Query( nativeQuery=true, value="SELECT dist.nome, dist.id_distrito, dist.id_entidade, dist.id_municipio, dist.id_uf, dist.codigo_dne, dist.flag_ativo,  enti.nome Entidade, muni.nome Municipio, unfe.nome UF FROM glb.distritos  dist, glb.entidades  enti, glb.municipios muni, glb.ufs unfe WHERE dist.id_entidade  = enti.id_entidade AND dist.id_municipio = muni.id_municipio AND muni.id_uf = unfe.id_uf and enti.id_entidade = :parametroId order by nome   ")
    public  Page<Distritos>  encontrar(@Param ("parametroId")Long usuarioEntidade, int size, int page);

我收到了这个错误

Caused by: java.lang.IllegalArgumentException: Either use @Param on all parameters except Pageable and Sort typed once, or none at all!

我该如何解决？

Answer 1

你必须传递一个Pageable对象，而不是size和page：

public  Page<Distritos>  encontrar(@Param ("parametroId") Long usuarioEntidade, 
                                                          Pageable pageable);

并像这样调用你的方法

return distritosRepository.encontrar(usuarioEntidade, new PageRequest(size, page));

您可以创建一个包含已排序属性的Pageable对象，因此您可以在查询中使用order by nome而不是Sort sort = new Sort(new Sort.Order(Direction.ASC, "nome")); Pageable pageable = new PageRequest(size, page, sort); return distritosRepository.encontrar(usuarioEntidade, pageable);。

public static void longClickView(View v) {

    final int viewWidth = v.getWidth();
    final int viewHeight = v.getHeight();

    final float x = viewWidth / 2.0f;
    final float y = viewHeight / 2.0f;

    long downTime = SystemClock.uptimeMillis();
    long eventTime = SystemClock.uptimeMillis();

    MotionEvent event = MotionEvent.obtain(downTime, eventTime,
            MotionEvent.ACTION_DOWN, x, y, 0);
    v.onTouchEvent(event);

    eventTime = SystemClock.uptimeMillis();
    final int touchSlop = ViewConfiguration.get(v.getContext()).getScaledTouchSlop();
    event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE,
            x + touchSlop / 2, y + touchSlop / 2, 0);
    v.onTouchEvent(event);

    v.postDelayed(() -> {
        long eventTime2 = SystemClock.uptimeMillis();
        MotionEvent event2 = MotionEvent.obtain(downTime, eventTime2, MotionEvent.ACTION_UP, x, y, 0);
        v.onTouchEvent(event2);
    }, (long) (ViewConfiguration.getLongPressTimeout() * 1.5f));
}

Answer 2

检查Spring提供的org.springframework.data.domain.Pageable类的分页。 Controller将提取您的参数并自动构建它。

Answer 3

改为传递Pageable对象：

public Page<Distritos> buscarFiltro(Long usuarioEntidade ,int size, int page){
       Pageable pageable = new PageRequest(page, size);
       return distritosRepository.encontrar(usuarioEntidade, pageable);
}

和回购：

public  Page<Distritos>  encontrar(@Param ("parametroId")Long usuarioEntidade
         , Pageable pageable);

除了Pageable之外的所有参数都使用@Param，并在Spring引导后键入Sort
