Annotation Interface Route

@Retention(RUNTIME) @Target(TYPE) @Inherited @Documented public @interface Route
Defines the route template suffix for components that function as navigation targets in routing.

The route template of the navigation target is composed of the values of all RoutePrefix annotated on the layout() and ParentLayout class values, starting from the root parent and joined together using slash delimiter to form a path form string.

There is also RouteAlias annotation which may be declared in addition to this annotation and may be used multiple times.

    • value

      String value
      Sets the route template suffix value of the annotated class.

      If no value is provided, the path will be derived from the class name of the component. The derived name will be in lower case and trailing "View" will be removed. Also, MainView or Main names will be mapped to root (value will be "").

      This value accepts also parameter template segments which can be defined using following format: :parameterName[?|*][(regex)].

      Note for framework developers: do not use the value directly, but use the helper method RouteUtil.resolve(VaadinContext, Class), so that naming convention based values are dealt correctly.

      Returns:
      the explicit path value of this route
      Default:
      "___NAMING_CONVENTION___"

    • layout

      Class<? extends RouterLayout> layout
      Sets the parent component for the route target component.

      When navigating between components that use the same layout, the same component instance is reused. Default layout target is the UI, but the layout should not be a custom UI as UI is a special class used to know where the route stack ends and no parent layouts should be involved.

      All layout stacks will be appended to the UI as it represents the Body element.

      Returns:
      the layout component class used by the route target component.

      Default:
      com.vaadin.flow.component.UI.class

    • absolute

      boolean absolute
      Ignore route prefixes from parent layouts and only use the path defined in this annotation.
      Returns:
      true to ignore parent layout prefixes, false otherwise
      Default:
      false

    • registerAtStartup

      boolean registerAtStartup
      Marks if this Route should be registered during the initial route registration on servlet startup.

      Default is to register route at startup.

      Returns:
      setting to false skips automatic registration
      Default:
      true
