您可以使用LazyDataModel。在此示例中，我将使用NetBeans通过“从实体创建JSF
CRUD页面”创建的BackBean和JpaController（BackBean必须为@SessionScoped）

private LazyDataModel<Car> lazyModel;
private int pageSize = 5;

public void setPageSize(int pageSize) {
    this.pageSize = pageSize;
}

public int getPageSize() {
    return pageSize;

public void LoadData() {
    lazyModel = new LazyDataModel<Car>() {

        @Override
        public List<Car> load(int first, int pageSize, String sortField, boolean sortOrder, Map<String, String> filters) {

            //Sorting and Filtering information are not used for demo purposes just random dummy data is returned

            List<Car> result = new ArrayList<Car>();

            try {
                result = getJpaController().findCarEntities(pageSize, first);
            } catch (Exception ex) {
                JsfUtil.addErrorMessage(ex, search);
            }

            return result;
        }
    };

    /** 
     * In a real application, this number should be resolved by a projection query 
     */
    lazyModel.setRowCount(getJpaController().getCarCount());
    lazyModel.setPageSize(pageSize);
}

public LazyDataModel<Car> getLazyModel() {
    return lazyModel;
}

我已经添加

    lazyModel.setPageSize(pageSize);

因为除以0知道问题http://code.google.com/p/primefaces/issues/detail?id=1544

        <p:dataTable  var="item" value="#{controller.lazyModel}"
                      rows="#{controller.pageSize}" paginator="true"
                      paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"  
                      rowsPerPageTemplate="9,12,15"
                      page=""
                      lazy="true"
                      dynamic="true"
                      id="pnlResult"
