struts2多文件上傳

1.web.xml配置 ，和之前一樣，就不說了

2.file.jsp

文件上傳
<form action="f_files.action" method="post" enctype="multipart/form-data">
    <input type="file" name="files">
    <input type="file" name="files">
    <input  type="submit" value="上傳">
</form>

   上傳文件必須用 enctype="multipart/form-data"

3.FileAction

 private File[] files;
 private String[] filesContentType;
 private String[] filesFileName;

加get 和 set方法

單個文件上傳就是-->

 private File uploadFile;
 private String uploadFileContentType;
 private String uploadFileFileName;

加get 和 set方法

/**
     * 多文件上傳
     * 鄭平
     * @return
     * 2014-7-23
     */
    public String files(){
        System.out.println("多文件上傳");
        String realPath = "E:\\現計/images";
        File f = new File(realPath);
        if(!f.exists()){
            f.mkdirs();
        }
        System.out.println("file.length:"+files.length);
        for(int i=0;i<files.length;i++){
            System.out.println("filesFileName[i]):"+filesFileName[i]);
            File fe = files[i];
            try {
                FileUtils.copyFile(fe, new File(f, filesFileName[i]));
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        return "success";
    }

 4..file.xml中配置

<struts>
        <constant name="struts-multipart.maxSize" value="16777216"></constant>
        <package name="file" extends="struts-default">
            <action name="file_*" class="com.filed.action.FiledUpload" method="{1}">
                <result name="success">/success.jsp</result>
                <result name="input" >/default.jsp</result>
            </action>
        </package>
    </struts>

 5.struts.xml配置

Java代碼

<include file="com/struts/config/file.xml"></include>
