• Struts1.x上传


    1,jsp页面上传控件

    <form action="/easyuiSSH/model/upload.do" enctype="multipart/form-data" method="post">
    <input type="file" name="myfile"/>
    <html:submit/><html:cancel/>
    </form>

    2,form定义上传文件类型

    package com.platform_easyuiSSH.struts1.action.form;

    import org.apache.struts.action.ActionForm;
    import org.apache.struts.upload.FormFile;

    public class UploadForm extends ActionForm{
    /**
    * 序列号相当于类的身份证,如果你持久化操作,之后该类做了改动,在持久化会报错,而有了序列号,则会把持久化到硬盘的类一起改变

    */
    private static final long serialVersionUID = 1L;
    private FormFile myfile;

    public FormFile getMyfile() {
    return myfile;
    }

    public void setMyfile(FormFile myfile) {
    this.myfile = myfile;
    }
    }

    3,action执行上传操作

    package com.platform_easyuiSSH.struts1.action;

    import java.io.FileOutputStream;
    import java.io.InputStream;
    import java.io.OutputStream;

    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    import org.apache.struts.action.Action;
    import org.apache.struts.action.ActionForm;
    import org.apache.struts.action.ActionForward;
    import org.apache.struts.action.ActionMapping;
    import org.apache.struts.upload.FormFile;

    import com.platform_easyuiSSH.struts1.action.form.UploadForm;

    public class UploadAction extends Action{
    @Override
    public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response)
    throws Exception {
    UploadForm uf = (UploadForm) form;
    FormFile myfile = uf.getMyfile();
    //文件名
    String fileName = myfile.getFileName();
    //文件大小
    int fileSize = myfile.getFileSize();
    //文件类型
    String fileType = myfile.getContentType();
    System.out.println("文件名:"+fileName+" 文件大小:"+fileSize+" 文件类型:"+fileType);

    String realPath = request.getSession().getServletContext().getRealPath("/upload");
    System.out.println(realPath);
    if( fileSize != 0){
    //输入流接收文件,字节数组太小不适合
    InputStream is = myfile.getInputStream();
    byte[] buf = new byte[1024];
    OutputStream os = new FileOutputStream(realPath+"\"+fileName);
    while(true){
    int len = is.read(buf);
    if(len == -1){
    break;
    }
    os.write(buf, 0, len);
    }
    os.close();
    is.close();
    }
    return mapping.findForward("logoutSuccess");
    }
    }
