页面核心代码：

struts.xml核心配置代码

<constant name="struts.multipart.maxSize" value="204800" />

  <action name="import">
   <result>/WEB-INF/jsp/common/import.jsp</result>
  </action>
  <action name="file_upload"
   class="com.doximi.logistics.actions.common.FileUploadAction">
   <interceptor-ref name="baseStack"/>
   <interceptor-ref name="fileUpload">
    <param name="allowedTypes">

   </interceptor-ref>
   <result name="error">/page/error.jsp</result>
   <result name="success">/page/success.jsp</result>
  </action>
</package>

java核心代码:

public class FileUploadAction extends ActionSupport {

/**
*
*/
private static final long serialVersionUID = 1L;
private File upFile;
private String upFileFileName; // 文件名
private String upFileContentType; // 文件类型
private String upFileCaption; // 文件备注
//getter,setter省略
public String execute() throws Exception {
  System.out.println("\n文件名:" + upFileFileName);
  System.out.println("文件类型：" + upFileContentType);

  //获取当前项目绝对路径+拼接文件路径
  //注意如果目标文件夹(upload)不存在可能会找不到上传的文件
  String filePath = ServletActionContext.getServletContext().getRealPath(
    "/upload")
    + "/" + upFileFileName;
  File tarFile = new File(filePath);

  try {
   copyFile(upFile, tarFile);
  } catch (Exception e) {
   e.printStackTrace();
   return ERROR;
  }
  System.out.println("文件存放位置:"+filePath+"\n");
  return SUCCESS;
}

/**
* 复制文件
*
* @param java
*            .io.File src
* @param java
*            .io.File tar
* @throws IOException
*/
private void copyFile(File src, File tar) throws IOException {
  InputStream inputStream = new FileInputStream(src);
  OutputStream outputStream = new FileOutputStream(tar);
  System.out.println("文件大小:" + inputStream.available());
  byte[] content = new byte[1024];
  while (inputStream.read(content) > 0) {
   outputStream.write(content);
  }
  outputStream.close();
  inputStream.close();
}

}

访问URL

common/import.action

完工

注意：

上传页面中的

name要对应java代码中的字段。

半年没写代码竟然连这都忘记了，弄一下午猛然发现没对应，难道脑袋被门卡了还没好？

郁闷，郁闷。。。
