java - 计划事件是在前一天创建的

Question

我正在尝试使用数据库实现 Primefaces Schedule:

        <p:outputLabel for="from" value="From:" />
        <p:calendar id="from" value="#{schedule.event.startDate}" timeZone="GMT+2" pattern="dd/MM/yyyy HH:mm"/>

        <p:outputLabel for="to" value="To:" />
        <p:calendar id="to" value="#{schedule.event.endDate}" timeZone="GMT+2" pattern="dd/MM/yyyy HH:mm"/>

        <p:outputLabel for="allDay" value="All Day:" />
        <h:selectBooleanCheckbox id="allDay" value="#{schedule.event.allDay}" />

        <p:commandButton type="reset" value="Reset" />
        <p:commandButton id="addButton" value="Save" actionListener="#{schedule.addEvent}" oncomplete="PF('myschedule').update();PF('eventDialog').hide();" />

        <p:commandButton value="Delete" oncomplete="PF('myschedule').update(); PF('eventDialog').hide();"
                         actionListener="#{schedule.deleteEvent}"/>
    </h:panelGrid>
</p:dialog>

CDI bean :

@Resource(name = "jdbc/DefaultDB")
private DataSource ds;
private ScheduleModel lazyEventModel;
private ScheduleEvent event = new DefaultScheduleEvent();

@PostConstruct
public void init()
{
    lazyEventModel = new LazyScheduleModel()
    {
        @Override
        public void loadEvents(Date start, Date end)
        {
            try
            {                   
                Connection conn = ds.getConnection();
                PreparedStatement ps = null;
                try
                {
                    ps = conn.prepareStatement("SELECT * FROM SCHEDULE WHERE START_DATE >= ? AND END_DATE < ?");

                    ps.setDate(1, new java.sql.Date(start.getTime()));
                    ps.setDate(2, new java.sql.Date(end.getTime()));
                    ResultSet rs = ps.executeQuery();
                    while (rs.next())
                    {
                        addEvent(new DefaultScheduleEvent(rs.getString("TITLE"), rs.getDate("START_DATE"), rs.getDate("END_DATE")));
                    }
                }
                finally
                {
                    if (ps != null)
                    {
                        ps.close();
                    }
                    conn.close();
                }
            }
            catch (Exception ex)
            {
                ex.printStackTrace();
            }
        }
    };

    addMessage(message);

{
    FacesContext.getCurrentInstance().addMessage(null, message);

    Connection conn = ds.getConnection();
    PreparedStatement ps = null;
    boolean committed = false;
    try

        if (ps != null)
        {
            ps.close();
        }
        conn.close();
    }
}

当我使用对话框创建新事件时，我成功地在前一天创建了新事件。当我插入新事件时，我将 java.util.Date 转换为 java.sql.Date。

你能告诉我如何解决这个问题吗？

在您的 .xhtml 文件中，将其添加到其中

<p:schedule clientTimeZone="local"> </p:schedule>
