jsp ajax上传标签原始版本


好久没有更新博客了,写了个jsp 上传组件给大家看看

  1.下载下来,新建个j2ee工程,把qingcai-upload.jar放到lib下,然后upload.tld放到WEB-INF下。

  2.在web.xml

  例如:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_4.xsd"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_4.xsd"
 id="WebApp_ID" version="2.4">
  <display-name>aa</display-name>
 <welcome-file-list>
  <welcome-file>index.html</welcome-file>
  <welcome-file>index.htm</welcome-file>
  <welcome-file>index.jsp</welcome-file>
  <welcome-file>default.html</welcome-file>
  <welcome-file>default.htm</welcome-file>
  <welcome-file>default.jsp</welcome-file>
 </welcome-file-list>
 <taglib>
  <taglib-uri>/upload</taglib-uri>
  <taglib-location>/WEB-INF/upload.tld</taglib-location>
 </taglib>
 <servlet>
  <servlet-name>UploadServlet</servlet-name>
  <servlet-class>com.qingcai.upload.servlet.UploadServlet</servlet-class>
  <init-param>
   <param-name>savePath</param-name>
   <param-value>C:\\upload\\</param-value>
  </init-param>
  <init-param>
   <param-name>extension</param-name>
   <param-value>gif,rar</param-value>
  </init-param>
  <init-param>
   <param-name>maxFileSize</param-name>
   <param-value>20</param-value>
  </init-param>
 </servlet>
 <servlet-mapping>
  <servlet-name>UploadServlet</servlet-name>
  <url-pattern>/fileupload</url-pattern>
 </servlet-mapping>
</web-app>

  3.新建个jsp

  如

<%@ page language="java" contentType="text/html; charset=GBK"
    pageEncoding="GBK"%>
        <%@ taglib uri="/upload" prefix="qingcaiUpload"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>Insert title here</title>
</head>
<body>
<qingcaiUpload:upload/>
</body>
</html>

  这样就可以调用了

  这才是最基础的上传,我近几天会把功能做的更完善点,然后会把代码发出来,一起去研究,一起探讨。
