Question

我正在学习Spring MVC和Spring Security。

当de lallow linha返回false时，如何在页面上进行重定向？ dentro de um @Controller？

@PostAuthorize(" hasRole('page')")

如果上面的行返回true则没有问题。

如果上面的linha返回false页面仍然呈现！但是所有变量都是空的，例如：显示一个带头且没有任何行的简单表。

问：@PostAuthorize返回false时如何重定向？

处理控制器建议中的AccessDeniedException异常

    self.category_tree = QTreeWidget(self.framemain)
    self.category_tree.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
    self.category_tree.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOff)
    self.category_tree.setGeometry(QRect(630, 90, 161, 381))
    self.category_tree.setLayoutDirection(Qt.RightToLeft)
    self.category_tree.setLocale(QLocale(QLocale.Persian, QLocale.Iran))
    self.category_tree.setEditTriggers(QAbstractItemView.NoEditTriggers)
    self.category_tree.setUniformRowHeights(False)
    self.category_tree.setColumnCount(1)
    self.category_tree.setObjectName("category_tree")
    self.category_tree.headerItem().setText(0, "1")
    self.category_tree.setFrameShape(QFrame.NoFrame)
    self.category_tree.header().setVisible(False)
    self.category_tree.header().setSortIndicatorShown(False)
    self.category_tree.setFocusPolicy(Qt.NoFocus)
    self.category_tree.verticalScrollBar().setSingleStep(25)

def checkscroll(self,startx,endx):
    if (startx - endx) >= 25:
    #swipe from right to left
        self.category_tree.verticalScrollBar().setSliderPosition(self.category_tree.verticalScrollBar().sliderPosition()+(25))
    elif (startx - endx) <= -25:
            self.category_tree.verticalScrollBar().setSliderPosition(self.category_tree.verticalScrollBar().sliderPosition()-abs(25))
