JSF&RichFaces配置方法-优快云博客

本文介绍如何配置JSF及引入JBOSS RichFaces增强UI体验。详细讲解了JSF的基本配置步骤，包括web.xml配置、faces-config.xml创建及Spring集成等。同时介绍了RichFaces的配置方法，包括web.xml设置、支持库添加与标签导入。

最近在一个项目中用到JSF来进行开发，JSF用的是SUN的标准包，感觉UI支持略显单薄。上个月开始引入JBOSS的Richfaces，感觉很好很强大，特别是a4j组件...

1. 配置JSF

配置web.xml

<context-param>
    <param-name>javax.faces.CONFIG_FILES</param-name>
    <param-value>/WEB-INF/faces-config.xml</param-value>
 </context-param> 

<context-param>
     <param-name>javax.faces.STATE_SAVING_METHOD</paramname>
      <param-value>client</param-value>
</context-param> 

<context-param>
        <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
        <param-value>.xhtml</param-value>
 </context-param> 

<servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

添加支持库文件

如果是使用J2EE5.0 则已经加入了支持文件库

JSF标签
A、JSP
<%@taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
B、XHTML
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f=http://java.sun.com/jsf/core

4、建立faces-config.xml,文件位置/WEB-INF/faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>

</faces-config>

5、在JSF中加入Spring支持：在faces-config.xml文件中加入如下配置：

<application>
        <variable-resolver>
            org.springframework.web.jsf.DelegatingVariableResolver
        </variable-resolver>
</application>

2. 配置RichFaces

配置web.xml

<context-param>
        <param-name>org.ajax4jsf.SKIN</param-name>
        <param-value>blueSky</param-value>
 </context-param> 

<context-param>
        <param-name>org.ajax4jsf.COMPRESS_SCRIPT</param-name>
        <param-value>false</param-value>
 </context-param> 

<filter>
        <display-name>Ajax4jsf Filter</display-name>
        <filter-name>ajax4jsf</filter-name>
        <filter-class>org.ajax4jsf.Filter</filter-class>
        <init-param>
            <param-name>forceparser</param-name>
            <param-value>false</param-value>
        </init-param>
</filter>
<filter-mapping>
        <filter-name>ajax4jsf</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
</filter-mapping>

添加支持库

可以到JBOSS官方网站下载http://labs.jboss.com/jbossrichfaces/

richfaces-api-3.1.4.GA.jar

richfaces-impl-3.1.4.GA.jar

richfaces-ui-3.1.4.GA.jar

RichFaces标签导入

A、JSP

<%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%>
<%@ taglib uri="http://richfaces.ajax4jsf.org/rich" prefix="rich"%>

B、XHTML

xmlns:a4j="https://ajax4jsf.dev.java.net/ajax"
xmlns:rich="http://richfaces.ajax4jsf.org/rich"
