小编h2c*_*h2c的帖子

我正在使用JSP将blob文件从HTML表单上传到数据库.我需要将文件名插入DB.我知道文件名存储在Content-Disposition标题中,我怎么能得到它？

我正在使用JSF <h:inputFile>将图像上传到服务器.

<h:form enctype="multipart/form-data">
    <h:inputFile value="#{fileHandlerBean.file}"/>
    <h:commandButton action="#{fileHandlerBean.uploadImage()}"/>
</h:form>

我创建了一个虚拟主机/projectname/webapp/images.我可以成功地将文件创建到该文件夹​​中.

private Part file;

public String uploadImage(){
    InputStream is = null;
    try {
        String extension = FilenameUtils.getExtension(file.getSubmittedFileName());
        File tempFile = File.createTempFile("picture-", "."+extension, new File("/projectname/webapp/images"));
        Logger.getLogger("FILE SIZE").warning(String.valueOf(file.getSize()));
        Logger.getLogger("FILE EXTENSION").warning(extension);
        is = file.getInputStream();
        Logger.getLogger("STREAM AVAILABLE SIZE").warning(String.valueOf(is.available()));
        Files.copy(is, tempFile.toPath());
    } catch (IOException ex) {
        Logger.getLogger(FileHandlerBean.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        if( is!= null){
            try {
                is.close();
            } catch (IOException ex) {
                Logger.getLogger(FileHandlerBean.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }
    return "success";
}

但是所有这些都是空的,我 …

所以我做了一些用于发送消息的输入块,它在Chrome和Safari中工作正常,但Firefox用灰色边框显示它.在IE中也存在一个问题,因为它会让它们变大,直到你激活它,然后它会回到正常大小.

<form action="" method="post">
<label for="name">
<input class="input1" type="text" placeholder="Your name" name="name" id="name"/>
</label>
<label for="E-mail">
<input class="input1" type="text" placeholder="Your e-mail" id="email"/>
</label>
<label for="Subject">
<input class="input1" type="text" placeholder="Subject" id="subject" />
</label>
<label for="Message">
<textarea class="input2" name="message" rows="20" cols="20" id="message" placeholder="Message"></textarea>
</label>
<label>
</form>
