The value selected is 2014, but I want that is 2016. How to do this? I'm using Primefaces.

选择的值是2014年，但我想要的是2016年。如何做到这一点呢?我用Primefaces。

You must include the attribute "value" in the element "selectOneMenu". Something like that:

您必须在元素“selectOneMenu”中包含属性“值”。这样的:

<p:selectOneMenu id="anios" value="#{pruebaCalendarBean.anioSeleccionado}">
    <f:selectItems value="#{pruebaCalendarBean.anios}" var="anio" itemLabel="#{anio}"       itemValue="#{anio}"  />
</p:selectOneMenu>

Then in your bean (pruebaCalendarBean) you must define a new attribute, in this case "anioSeleccionado" that represents the selected value in the dropdown

然后在您的bean (pruebaCalendarBean)中，您必须定义一个新属性，在这个例子中，“anioSeleccionado”表示下拉菜单中所选的值。
