File upload 将图像文件保存在jsf primefaces项目的特定目录中

File upload 将图像文件保存在jsf primefaces项目的特定目录中,file-upload,jsf-2,primefaces,directory,File Upload,Jsf 2,Primefaces,Directory,我想将byte[]文件保存到特定目录中: 我从这个方法中得到: public void setUploadedPicture(UploadedFile uploadedPicture) { System.out.println("set : "+uploadedPicture.getFileName()+" size : "+uploadedPicture.getSize()); this.uploadedPicture = uploadedPicture; }

我想将byte[]文件保存到特定目录中: 我从这个方法中得到:

public void setUploadedPicture(UploadedFile uploadedPicture)
{
    System.out.println("set : "+uploadedPicture.getFileName()+" size : "+uploadedPicture.getSize());        
    this.uploadedPicture = uploadedPicture;
}
我通过以下方式访问字节[]:

uploadedPicture.getContents()
我对此进行了测试,但没有结果

如何将其保存到项目内部或外部的特定目录中

多谢各位

*********编辑************ 以下是代码,但有时会出现错误:

public void setUploadedPicture(UploadedFile uploadedPicture)
{
    System.out.println("set : "+uploadedPicture.getFileName()+" size : "+uploadedPicture.getSize());        
    this.uploadedPicture = uploadedPicture;

    InputStream inputStr = null;
    try {
        inputStr = uploadedPicture.getInputstream();
    } catch (IOException e) {
        e.printStackTrace();
    }

    //create destination File
    String destPath = "C:\\"+uploadedPicture.getFileName();
    File destFile = new File(destPath);

    //use org.apache.commons.io.FileUtils to copy the File
    try {                    
        FileUtils.copyInputStreamToFile(inputStr, destFile);
    } catch (IOException e) {
        e.printStackTrace();
    }

}

感谢您提供这部分代码(我将对其进行测试),我不使用这种方法,因为我使用简单的uploadfile模式,然后我直接使用byte[]contentatbegin,
getInputStream()
无论采用何种上传模式,都应该可以正常工作。唯一的区别是它不会将整个文件放在服务器的内存中,因此效率更高。@pantominas我测试了你的代码,但问题是有时我在提交时会出现以下错误:
C:\Users\user\AppData\Local\Temp\upload\uuu54ab5703\u13da6c8fc2c\u8000\u00000016.tmp(Le fichier spécifi est introvable)
public void handleFileUpload(FileUploadEvent event) {  

    //get uploaded file from the event
    UploadedFile uploadedFile = (UploadedFile)event.getFile();

    //create an InputStream from the uploaded file
    InputStream inputStr = null;
    try {
        inputStr = uploadedFile.getInputstream();
    } catch (IOException e) {
        //log error
    }

    //create destination File
    String destPath = "your path here";
    File destFile = new File(destPath);

    //use org.apache.commons.io.FileUtils to copy the File
    try {                    
        FileUtils.copyInputStreamToFile(inputStr, destFile);
    } catch (IOException e) {
        //log error
    }
}
