JSF,Myfaces上传文件,以及不需要将excel保存到服务解析excel取出excel中的数据

Myeclipse7.0配置jsf就不用说了,上篇文章已经记载

这次教你们配置myfaces,网上有很多资料,我按照资料好顿配置

但是没有成功,我给你们分析下为什么没成功应该注意哪里

配置之前先把要用到的jar到入lib中,在我我的资源里已经有共享所有的jar

主要是配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <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>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.faces</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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>　　<servlet-name>Faces Servlet</servlet-name>　　</filter-mapping> </web-app><?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <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>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.faces</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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>　　<servlet-name>Faces Servlet</servlet-name>　　</filter-mapping> </web-app>

这个xml中要注意的是

<filter-mapping>　　<filter-name>ExtensionsFilter</filter-name>　　<servlet-name>Faces Servlet</servlet-name>　　</filter-mapping> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> 

 

这里的Faces Servlet的名字一定要对应上,否则不能提交服务请求

 

JSP代码,格式没调好 复制出自己调试,form里的属性 type="multipart/form-data" 必须要写上

 

<f:view><h:form enctype="multipart/form-data" ><x:inputFileUpload id="myFileId" value="#{MyBean.myFile}"storage="file" required="true" /><h:commandButton value="UPLOAD" action="#{MyBean.upload}"></h:commandButton></h:form></f:view>  

bean代码 这里上传excel的代码让我注释了

/** * */package com.jsf.bean;import java.io.BufferedOutputStream;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import jxl.Sheet;import jxl.Workbook;import jxl.read.biff.BiffException;import org.apache.commons.fileupload.FileItem;import org.apache.myfaces.custom.fileupload.UploadedFile;/** * @author Administrator * */public class MyBean {public MyBean() {}private UploadedFile myFile;public UploadedFile getMyFile() {return myFile;// org.apache.myfaces.component.html.util.ExtensionsFilter;// com.sun.faces.lifecycle.LifecycleImpl}public void setMyFile(UploadedFile myFile) {this.myFile = myFile;}public String upload() {try {String fileName = myFile.getName(); // 获得文件的全名，含路径try {Workbook workbook = Workbook.getWorkbook(myFile.getInputStream());Sheet sheet = workbook.getSheet(0);// 总行数int count = sheet.getRows();// 取出标题String a1 = sheet.getCell(0, 0).getContents();String a2 = sheet.getCell(1, 0).getContents();String a3 = sheet.getCell(2, 0).getContents();String a4 = sheet.getCell(3, 0).getContents();String a5 = sheet.getCell(4, 0).getContents();} catch (BiffException e) {// TODO Auto-generated catch blocke.printStackTrace();}// 上传excel// File temp = new File(fileName);// fileName = temp.getName();// 获得文件名//// BufferedOutputStream out = new BufferedOutputStream(// new FileOutputStream("d://" + fileName));// out.write(myFile.getBytes());// out.close();} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return "";}}

 

OK 完事
