JSF 文件上傳

后臺實現類：

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

import javax.faces.context.FacesContext;

import org.apache.myfaces.custom.fileupload.UploadedFile;

public class Fileupload

{

private UploadedFile _upFile;

private String _name = "";

public UploadedFile getUpFile()

{

return _upFile;

}

public void setUpFile(UploadedFile upFile)

{

_upFile = upFile;

}

public String getName()

{

return _name;

}

public void setName(String name)

{

_name = name;

}

public String upload() throws IOException

{

FacesContext facesContext = FacesContext.getCurrentInstance();

int start=_upFile.getName().lastIndexOf("\\")==-1?_upFile.getName().lastIndexOf("\\"):_upFile.getName().lastIndexOf("\\")+1;

String file=_upFile.getName().substring(start,_upFile.getName().length());

String path=Fileupload.class.getResource("/").getPath().substring(1,Fileupload.class.getResource("/").getPath().length());

path=path.replace("%20", " ")+file;

try {

FileOutputStream keyFOS = new FileOutputStream(path);

keyFOS.write(_upFile.getBytes());

keyFOS.close();

} catch (Exception e) {

System.out.println("lalala");

}

facesContext.getExternalContext().getApplicationMap().put("fileupload_bytes", _upFile.getBytes());

facesContext.getExternalContext().getApplicationMap().put("fileupload_type", _upFile.getContentType());

facesContext.getExternalContext().getApplicationMap().put("fileupload_name", _upFile.getName());

return path;

}

public boolean isUploaded()

{

FacesContext facesContext = FacesContext.getCurrentInstance();

return facesContext.getExternalContext().getApplicationMap().get("fileupload_bytes")!=null;

}

前臺實現：Myfaces

<t:inputFileUpload id="fileupload"

value="#{action$fixing.myFile}"

storage="file"

styleClass="fileUploadInput"

maxlength="200000"/>

<h:commandButton value="#{prompt['Submit']}"

action="#{action$fixing.sel}" />

后臺管理Bean：

import org.apache.myfaces.custom.fileupload.UploadedFile;

public class FixingAction{

private UploadedFile myFile;

public UploadedFile getMyFile() {

return myFile;

}

public void setMyFile(UploadedFile myFile) {

this.myFile = myFile;

}

public String sel(){

Fileupload file=new Fileupload();

String path=file.setUpFile(this.myFile);

System.out.println("文件存放路徑："+path);

return null;

}
