PrimeFaces 11迁移：如何替换已移除的DataTableFeatureKey？

在PrimeFaces 11中，DataTableFeatureKey枚举已被移除，取而代之的是使用字符串常量作为特性映射的键值。以下是针对你原有代码的兼容替换方案：

替换后的代码实现 #

static Map<String, DataTableFeature> FEATURES;

static {
    FEATURES = new HashMap<>();
    FEATURES.put("filter", new ScwFilterFeature());
    FEATURES.put("page", new PageFeature());
    FEATURES.put("sort", new SortFeature());
    FEATURES.put("resizableColumns", new ResizableColumnsFeature());
    FEATURES.put("select", new SelectionFeature());
    FEATURES.put("rowEdit", new RowEditFeature());
    FEATURES.put("cellEdit", new CellEditFeature());
    FEATURES.put("rowExpand", new RowExpandFeature());
    FEATURES.put("scroll", new ScrollFeature());
    FEATURES.put("draggableRows", new DraggableRowsFeature());
}

关键说明 #

• 泛型调整：将原Map<DataTableFeatureKey, DataTableFeature>改为Map<String, DataTableFeature>，使用字符串作为特性标识键。
• 键值对应关系：原枚举值与新字符串键的一一对应如下：
  • DataTableFeatureKey.FILTER → "filter"
  • DataTableFeatureKey.PAGE → "page"
  • DataTableFeatureKey.SORT → "sort"
  • DataTableFeatureKey.RESIZABLE_COLUMNS → "resizableColumns"
  • DataTableFeatureKey.SELECT → "select"
  • DataTableFeatureKey.ROW_EDIT → "rowEdit"
  • DataTableFeatureKey.CELL_EDIT → "cellEdit"
  • DataTableFeatureKey.ROW_EXPAND → "rowExpand"
  • DataTableFeatureKey.SCROLL → "scroll"
  • DataTableFeatureKey.DRAGGABLE_ROWS → "draggableRows"
• 自定义特性兼容性：确保你的自定义特性类（如ScwFilterFeature）继承PrimeFaces 11中对应的基础特性类（例如org.primefaces.component.datatable.feature.FilterFeature），以保证API兼容性。
