Struts文件上传功能的实现_struts-config怎么配置fileuploadbase-优快云博客

工具： myeclipse 6.5

1. 新建项目 StrutsFileUpload

导入 struts1.x 的属性包：

在 struts-config.xml 里面新建一个 action 和 form 为 fileupload

struts-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">

<struts-config>
<form-beans >
    <form-bean name="fileuploadForm" type="com.shiryu.form.FileuploadForm" />
</form-beans>

<global-exceptions />
<global-forwards />
<action-mappings >
    <action
      attribute="fileuploadForm"
      input="/fileupload.jsp"
      name="fileuploadForm"
      path="/fileupload"
      scope="request"
      type="com.shiryu.action.FileuploadAction">
      <forward name="index" path="/index.jsp" />
    </action>

</action-mappings>

<message-resources parameter="com.shiryu.ApplicationResources" />
</struts-config>

2.com.shiryu.action 包下的 FileuploadAction.java

package com.shiryu.action;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
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.shiryu.form.FileuploadForm;

public class FileuploadAction extends Action {

    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response) {

        FileuploadForm fileuploadForm = (FileuploadForm) form;

        FormFile upfile=fileuploadForm.getFilecontext();

        // 文件上传功能实现
        try {

            byte[] buf=upfile.getFileData();

                OutputStream out=new FileOutputStream(new File("d://"+fileuploadForm.getFilecontext().toString()));

                out.write(buf);

                out.close();

        } catch (FileNotFoundException e) {
                e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return mapping.findForward("index");
    }
}

3.com.shiryu.form 包下的 FileuploadForm.java

package com.shiryu.form;

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

public class FileuploadForm extends ActionForm {

    private static final long serialVersionUID = 5572854553277148095L;

     // 类型是 FormFile
    private FormFile filecontext;

    private String filename;

    public FormFile getFilecontext() {
        return filecontext;
    }

    public String getFilename() {
        return filename;
    }

    public void setFilename(String filename) {
        this.filename = filename;
    }

    public void setFilecontext(FormFile filecontext) {
        this.filecontext = filecontext;
    }
}
