我正在尝试使用 setPropertyActionListener 设置枚举属性,但我不知道该怎么做。这是实体:
@Entity
public class Invoice {
public enum InvoiceStatus { ACTIVE, CANCELED }
...
@Enumerated(EnumType.STRING)
private InvoiceStatus status;
...
public InvoiceStatus getStatus() {
return status;
}
public void setStatus(InvoiceStatus status) {
this.status = status;
}
这是命令按钮,假设使用 setPropertyActionListener 将状态设置为 ACTIVE
...
<h:form id="invoiceCreatedSuccessfully">
<p:dialog header="#{msg['title.success']}" widgetVar="invoiceCreatedSuccessfullyDialog" resizable="false" showEffect="fade" hideEffect="fade">
<h:panelGrid columns="2" rows="3" style="margin-bottom: 10px">
<h:outputText value="#{msg['message.invoiceCreatedSuccessfully']}" />
</h:panelGrid>
<p:commandButton value="#{msg['label.acknowledged']}" actionListener="#{invoiceManager.reload}" action="viewInvoices">
<f:setPropertyActionListener target="#{invoiceManager.invoice.status}" value="ACTIVE" />
</p:commandButton>
</p:dialog>
</h:form>
未报告错误,但未设置数据库中的“状态”字段。有人能告诉我为什么吗?
