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: <?xml version="1.0" encoding="UTF-8"?> javax.faces.STATE_SAVING_METHOD client <!-- Context Listener creates and sets the application handler --> <!-- Faces Servlet --> Faces Servlet javax.faces.webapp.FacesServlet 1 <!-- Faces Servlet Mapping --> Faces Servlet *.jsf ExtensionsFilter org.apache.myfaces.component.html.util.ExtensionsFilter uploadMaxFileSize 10m uploadThresholdSize 100k ExtensionsFilter 中的一致--> Faces Servlet index.html 上传文件的页面如下: <%@ include file="tags.jsp"%> 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: myBean fileupload.MyBean request 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() { return myFile; } public void setMyFile(UploadedFile myFile) { this.myFile = myFile; } public String uploadedfile() { 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
