Question

我正在使用primefaces 3.4.2 jar。我有一个有四列的数据表。在两列中，我有一个datalist，我想导出datalist显示的文本。但是当我导出它时，它会显示以下内容＆＃34; org.primefaces.component.datalist.DataList@1195cc3"在pdf和xls文件中。

  <p:dataTable emptyMessage="#{messages['empty.result.set']}" id="searchResult" var="row" value="#{managePessoaJuridica.manageableList}" rows="10" paginator="true" paginatorPosition="top" paginatorAlwaysVisible="false" style="display:#{managePessoaJuridica.manageableList == null? 'none': ''}">
        <p:column styleClass="column_icons" exportable="false">
            <p:panelGrid columns="#{pessoaJuridicaController.showSelectAction?3:2}">

                    onclick="return confirm('#{messages['confirm.delete.this']} #{messages['pessoa.juridica.view.title']}');" />

Answer 1

但是当我导出它时，它会显示以下内容 pdf和中的“org.primefaces.component.datalist.DataList@1195cc3” xls文件。

显然，Primefaces的数据导出器使用对象的toString（）方法来打印其“值（s）”。

建议：

编写自定义导出程序（推荐）
覆盖toString()的{{1}}方法（不建议）

导出文本然后在Excel中使用datalist，使用dataexporter导出pdf
