MyFaces
MyFaces используется как реализация JSF в этом приложении. Следующие детали должны быть добавлены в web.xml

PrimeFaces Theme.
Как уже было сказано, библиотека PrimeFaces используется для улучшения пользовательского интерфейса. Для этой библиотеки настройки почти не требуются. PrimeFaces предоставляет множество предварительно разработанных тем для вашего веб-приложения. В нашем случае мы используем тему «голубое небо». Мы просто добавляем следующий параметр в web.xml

<context-param>
  <param-name>primefaces.THEME</param-name><param-value>glass-x</param-value></context-param>

Интеграция JSF и Spring:
Чтобы интегрировать JSF с Spring, необходимо указать SpringBeanFacesELResolver в Faces-config.xml
Faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"

  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
   <application>
     <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
   </application>
   <factory>
 <partial-view-context-factory>org.primefaces.context.PrimePartialViewContextFactory</partial-view-context-factory>
   </factory>
</faces-config>

Сведения
