1. web.xml 写全文拦截器
WEBROOT--- WEB-INF ---- WEB.XML
<filter> <filter-name>Struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>Struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
2.写个文件上传页面
WEBROOT--E文件夹下----- upload.jsp
<body>
<form action="${pageContext.request.contextPath }/fileuploadaction" method="post" enctype="multipart/form-data">
用户名:<input type="text" name="username"><br/>
文件:<input type="file" name="file1"><br/>
<input type="submit" value="上传">
</form>
</body>
3. 项目文件下 struts.xml
<struts>
<!-- 二、总配置文件：引入其他所有配置文件 -->
<include file="cn/itcast/e_fileupload/upload.xml"></include>
</struts>
4. 项目src下 建立包： cn.itcast.e_fileupload 下 新建 upload.xml
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="upload_" namespace="/" extends="struts-default" abstract="false"> <action name="fileuploadaction" class="cn.itcast.e_fileupload.fileupload" > <result name="success">/e/success.jsp</result> </action> </package> </struts>
5. cn.itcast.e_fileupload 下新建 fileupload.java
package cn.itcast.e_fileupload; import java.io.File; import org.apache.commons.io.FileUtils; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; public class fileupload extends ActionSupport{ private File file1; private String file1FileName; //该变量 固定格式 "file1" + FileName(注意大小写) private String file1ContextType; //该变量 固定格式 public void setFile1(File file1) { this.file1 = file1; } public void setFile1filename(String file1FileName) { this.file1FileName = file1FileName; } public void setFile1contexttype(String file1ContextType) { this.file1ContextType = file1ContextType; } @Override public String execute() throws Exception { String path=ServletActionContext.getServletContext().getRealPath("/upload"); File desfile=new File(path,file1FileName); FileUtils.copyFile(file1, desfile); return SUCCESS; } }
