我使用PF 4.0编写了一个JSF应用程序。它工作正常，但是来自ManagedBean的日期不正确。我检查了日志。它在dateSelect事件上是正确的，但它显示前一天＆lt; p：inputMask＆gt;。问题是什么？这是我的代码：
的index.xhtml
<h:form id="form">
<p:growl id="messages" showDetail="true" />
<p:schedule id="schedule" value="#{scheduleController.eventModel}" widgetVar="myschedule">
<p:ajax event="dateSelect" listener="#{scheduleController.onDateSelect}" update="eventDetails" oncomplete="PF('eventDialog').show()" />
<p:ajax event="eventSelect" listener="#{scheduleController.onEventSelect}" update="eventDetails" oncomplete="PF('eventDialog').show()" />
<p:ajax event="eventMove" listener="#{scheduleController.onEventMove}" update="messages" />
<p:ajax event="eventResize" listener="#{scheduleController.onEventResize}" update="messages" />
</p:schedule>
<p:dialog widgetVar="eventDialog" header="Event Details" showEffect="clip" hideEffect="clip">
<h:panelGrid id="eventDetails" columns="2">
<h:outputLabel for="title" value="Title:" />
<p:inputText id="title" value="#{scheduleController.event.title}" required="true"/>
<h:outputLabel for="from" value="From:" />
<p:inputMask id="from" value="#{scheduleController.event.startDate}" mask="99/99/9999">
<f:convertDateTime pattern="dd/MM/yyyy" />
</p:inputMask>
<h:outputLabel for="to" value="To:" />
<p:inputMask id="to" value="#{scheduleController.event.endDate}" mask="99/99/9999">
<f:convertDateTime pattern="dd/MM/yyyy" />
</p:inputMask>
<h:outputLabel for="allDay" value="All Day:" />
<h:selectBooleanCheckbox id="allDay" value="#{scheduleController.event.allDay}" />
<h:panelGrid columns="3" border="0">
<p:commandButton type="reset" value="Reset" />
<p:commandButton id="addButton" value="Save"
actionListener="#{scheduleController.addEvent}"
oncomplete="myschedule.update();eventDialog.hide();"/>
<p:commandButton value="Cancel" oncomplete="myschedule.update();eventDialog.hide();"
actionListener="#{scheduleController.cancelEvent}" />
</h:panelGrid>
</h:panelGrid>
</p:dialog>
</h:form>

我有同样的问题，我通过在计划组件中添加时区来解决它。
<p:schedule id="schedule" value="#{turnoController.eventModel}" widgetVar="myschedule" locale="es" timeZone="GMT-3">
<p:ajax event="dateSelect" listener="#{turnoController.onDateSelect}" update=":TurnoCreateDlg :growl" oncomplete="PF('TurnoCreateDialog').show()" />
<p:ajax event="eventSelect" listener="#{turnoController.onEventSelect}" update=":TurnoCreateDlg :growl" oncomplete="PF('TurnoCreateDialog').show()" />
</p:schedule>
在这种情况下布宜诺斯艾利斯的时区

最有可能的是，这是一个时区问题。即使它不是，那就是你应该开始寻找的地方你还没有为convertDateTime组件设置时区。假设你在GMT + 1，它应该是：
<p:inputMask id="from" value="#{scheduleController.event.startDate}" mask="99/99/9999">
<f:convertDateTime pattern="dd/MM/yyyy" timeZone="GMT+1" type="date" />
</p:inputMask>
您的日历也是如此
private Calendar today() {
Calendar calendar = Calendar.getInstance();
calendar.setTimeZone(TimeZone.getTimeZone("GMT+1"));
calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DATE), 0, 0, 0);
return calendar;
}

为了解决这个问题，我增加了一天（+1）。它不是最好的解决方案，但对我有用，并且不会影响太多。
