Question

我正在尝试使用this在Primefaces数据表中实现selectOneMenu作为过滤器。当我尝试过滤数据表时，它显示每次都没有找到记录。如果我错过了什么，请告诉我。

<p:column filterBy="#{book.timeSlotId}" filterMatchMode="exact">

                            <f:facet name="header">
                                <h:outputText value="#{bundle.ListBookingDetailsTitle_timeSlotId}"/>
                            </f:facet>
                            <f:facet name="filter" >
                                <p:selectOneMenu  onchange="PF('bookDetTable').filter()"   >
                                    <f:selectItem itemLabel="Select One" itemValue="#{null}" 
                                                  noSelectionOption="true" />
                                    <f:selectItems value="#{bookingTimeSlotsController.itemsAvailableSelectOne}"
                                                    var="timeSlotIdItem"
                                                    itemValue="#{timeSlotIdItem}" itemLabel="#{timeSlotIdItem.toString()}" />
                                </p:selectOneMenu>
                            </f:facet>
                            <h:outputText value="#{book.timeSlotId.toString()}"/>
                        </p:column>

任何帮助都很适合。

实体类确实有hashCode（）和equals方法

@Override
public int hashCode() {
    int hash = 0;
    hash += (timeSlotId != null ? timeSlotId.hashCode() : 0);
    return hash;
}

@Override
public boolean equals(Object object) {
    // TODO: Warning - this method won't work in the case the id fields are not set
    if (!(object instanceof BookingTimeSlots)) {
        return false;
    }
    BookingTimeSlots other = (BookingTimeSlots) object;
    if ((this.timeSlotId == null && other.timeSlotId != null) || (this.timeSlotId != null && !this.timeSlotId.equals(other.timeSlotId))) {
        return false;
    }
    return true;
}

@Override
public String toString() {
    return JsfUtil.convertTimetoString(timeSlotStime) + " - " + JsfUtil.convertTimetoString(timeSlotEtime);
}

转换器

@FacesConverter(forClass = BookingTimeSlots.class)
public static class BookingTimeSlotsControllerConverter implements Converter {

    @Override
    public Object getAsObject(FacesContext facesContext, UIComponent component, String value) {
        if (value == null || value.length() == 0) {
            return null;
        }
        BookingTimeSlotsController controller = (BookingTimeSlotsController) facesContext.getApplication().getELResolver().
                getValue(facesContext.getELContext(), null, "bookingTimeSlotsController");
        return controller.getFacade().find(getKey(value));
    }

    java.lang.Integer getKey(String value) {
        java.lang.Integer key;
        key = Integer.valueOf(value);
        return key;
    }

    String getStringKey(java.lang.Integer value) {
        StringBuilder sb = new StringBuilder();
        sb.append(value);
        return sb.toString();
    }

    @Override
    public String getAsString(FacesContext facesContext, UIComponent component, Object object) {
        if (object == null) {
            return null;
        }
        if (object instanceof BookingTimeSlots) {
            BookingTimeSlots o = (BookingTimeSlots) object;
            return getStringKey(o.getTimeSlotId());
        } else {
            Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, "object {0} is of type {1}; expected type: {2}", new Object[]{object, object.getClass().getName(), BookingTimeSlots.class.getName()});
            return null;
        }
    }

}

也许我错过了什么。如果有人能突出，会非常高兴。请帮助我!!
