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 block e.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 block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return ""; } }

OK 完事
