JSF，依賴於maven的環境搭建

依賴於maven，所以先配置pom.xml文件

pom.xml的配置請參考：

http://blog.csdn.net/limiteewaltwo/article/details/8796332

web.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<!-- 解決上傳亂碼問題 -->
	<filter>
		<filter-name>Character Encoding Filter</filter-name>
		<filter-class>com.vs.myjsf.filter.CharacterEncodingFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>Character Encoding Filter</filter-name>
		<servlet-name>Faces Servlet</servlet-name>
	</filter-mapping>
	<context-param>
		<param-name>javax.faces.CONFIG_FILES</param-name>
		<param-value>/WEB-INF/faces-config.xml</param-value>
	</context-param>
	<description>
		JSF Demo
	</description>
	<display-name>JSF Demo</display-name>
	<servlet>
		<servlet-name>Faces Servlet</servlet-name>
		<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>Faces Servlet</servlet-name>
		<url-pattern>*.xhtml</url-pattern>
	</servlet-mapping>
	
  <welcome-file-list>
    <welcome-file>/index.xhtml</welcome-file>
  </welcome-file-list>
</web-app>

faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
	<application>
		<locale-config>
			<default-locale>en</default-locale>
			<supported-locale>zh_CN</supported-locale>
		</locale-config>
	</application>
</faces-config>

JSF2.0中，推薦使用註解方式，所以faces-config.xml只推薦配置一些基本的參數。

統一使用utf-8編碼，解決中文亂碼問題，web.xml中的過濾器如下：

package com.vs.myjsf.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class CharacterEncodingFilter implements Filter {

	public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
		req.setCharacterEncoding("UTF-8");
		resp.setCharacterEncoding("UTF-8");
		chain.doFilter(req, resp);
	}

	public void init(FilterConfig filterConfig) throws ServletException {
		
	}
	
	public void destroy() {
		
	}
}

配置基本完成。
