JSF文件上传

依赖的文件： tomahawk-1.1.3.jar commons-fileupload-1.2.jar commons-io-1.3.1.jar Tomahawk.tld 把这个三个包放在/WEB_INF/lib目录下面。Jsf依赖的包也放在这个目录下面 Tomahawk.tld放在/WEB-INF目录下。Jsf标签也放在这个目录下面。 这个主要讲jsf上传文件，因此只罗列了上传文件用到的包和标签。 Web-xml文件如下： &lt;?xml version="1.0" encoding="UTF-8"?&gt; <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <context-param> <param-name>javax.faces.STATE_SAVING_METHOD</param-name> <param-value>client</param-value> </context-param> &lt;!-- Context Listener creates and sets the application handler --&gt; &lt;!-- Faces Servlet --&gt; <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> &lt;!-- Faces Servlet Mapping --&gt; <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> <filter> <filter-name>ExtensionsFilter</filter-name> <filter-class> org.apache.myfaces.component.html.util.ExtensionsFilter </filter-class> <init-param> <param-name>uploadMaxFileSize</param-name> <param-value>10m</param-value> </init-param> <init-param> <param-name>uploadThresholdSize</param-name> <param-value>100k</param-value> </init-param> </filter> <filter-mapping> <filter-name>ExtensionsFilter</filter-name> <!—要和<servlet-mapping>中的<servlet-name>一致--&gt; <servlet-name>Faces Servlet</servlet-name> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app> 上传文件的页面如下： <%@ include file="tags.jsp"%> <f:view> <h:form id="MyForm" enctype="multipart/form-data" > <h:messages globalOnly="true" styleClass="message"/> <h:panelGrid columns="3" border="0" cellspacing="5"> <h:outputLabel for="myFileId" value="File: "/> <x:inputFileUpload id="myFileId" value="#{myBean.myFile}" storage="file" required="true"/> <h:message for="myFileId"/> <h:outputLabel for="myParamId" value="Param: "/> <h:selectOneMenu id="myParamId" value="#{myBean.myParam}" required="true"> <f:selectItem itemLabel="" itemValue=""/> <f:selectItem itemLabel="MD5" itemValue="MD5"/> <f:selectItem itemLabel="SHA-1" itemValue="SHA-1"/> <f:selectItem itemLabel="SHA-256" itemValue="SHA-256"/> <f:selectItem itemLabel="SHA-384" itemValue="SHA-384"/> <f:selectItem itemLabel="SHA-512" itemValue="SHA-512"/> </h:selectOneMenu> <h:message for="myParamId"/> <h:outputText value=" "/> <h:commandButton value="Submit" action="#{myBean.processMyFile}"/> <h:outputText value=" "/> </h:panelGrid> </h:form> </f:view> 其中tags.jsp文件如下： <%@ page language="java" pageEncoding="GB18030"%> <%@ page contentType="text/html" %> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %> <%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="x"%> Faces-config.xml文件如下： <faces-config> <managed-bean> <managed-bean-name>myBean</managed-bean-name> <managed-bean-class> fileupload.MyBean </managed-bean-class> <managed-bean-scope>request</managed-bean-scope> </managed-bean> </faces-config> MyBean如下： package com.dhc; import java.io.BufferedInputStream; import java.io.FileOutputStream; import java.io.InputStream; import javax.faces.application.FacesMessage; import javax.faces.context.FacesContext; import org.apache.myfaces.custom.fileupload.UploadedFile; public class oaMailMainForm { private UploadedFile myFile; public UploadedFile getMyFile&#40;&#41; { return myFile; } public void setMyFile&#40;UploadedFile myFile&#41; { this.myFile = myFile; } public String uploadedfile&#40;&#41; { System.out.println("Entry"); try { InputStream in = new BufferedInputStream(myFile.getInputStream()); try { byte[] buffer = new byte[64 * 1024]; FileOutputStream fileOutputStream = new FileOutputStream( "C:\\My Files\\tst.jpg");// 这里可以把上传的文件写服务器目录，或者数据库中 while (in.read(buffer) > 0) { fileOutputStream.write(buffer); } } finally { in.close(); } System.out.println("End"); return "success"; } catch (Exception x) { System.out.print("Exception"); FacesMessage message = new FacesMessage( FacesMessage.SEVERITY_FATAL, x.getClass().getName(), x .getMessage()); FacesContext.getCurrentInstance().addMessage(null, message); return null; } } } 参考文献：http://www.blogjava.net/cooky/archive/2007/10/02/150176.html http://blog.csdn.net/meteorlWJ/archive/2008/01/09/2032505.aspx http://tml808.javaeye.com/blog/166853
