upload.jsp这个页面选择提交文件，提交到uploadImage.action

<%@pagelanguage="java"contentType="text/html;charset=utf-8"
pageEncoding="utf-8"%>




Inserttitlehere



pleaseselectthefile:

FileUploadAction.java将传来的file进行处理

packageaction;

importjava.io.File;
importjava.io.FileInputStream;
importjava.io.FileOutputStream;

importorg.apache.commons.io.IOUtils;
importorg.apache.struts2.ServletActionContext;

importcom.opensymphony.xwork2.ActionSupport;

publicclassFileUploadActionextendsActionSupport{
privateFileupload;
privateStringuploadFileName;
privateStringuploadContentType;


publicFilegetUpload(){
returnupload;
}


publicvoidsetUpload(Fileupload){
this.upload=upload;
}


publicStringgetUploadFileName(){
returnuploadFileName;
}


publicvoidsetUploadFileName(StringuploadFileName){
this.uploadFileName=uploadFileName;
}


publicStringgetUploadContentType(){
returnuploadContentType;
}


publicvoidsetUploadContentType(StringuploadContentType){
this.uploadContentType=uploadContentType;
}


publicStringexecute(){
System.out.println(upload);
System.out.println(uploadContentType);
System.out.println(uploadFileName);

StringsavePath=ServletActionContext.getServletContext().getRealPath("/upload/"+this.uploadFileName);
System.out.println(savePath);

try{
FileInputStreamfis=newFileInputStream(upload);
FileOutputStreamfos=newFileOutputStream(savePath);
IOUtils.copy(fis,fos);
fos.flush();
fos.close();
fis.close();
}catch(Exceptione){
e.printStackTrace();
}
return"success";
}
}

uploadFileName和uploadContentType，这两个属性分别用于封装上传文件的文件名、上传文件的文件类型

Struts.xml配置


uploadSuccess.jsp
uploadError.jsp

成功失败界面随便写一个就行了，不贴了。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持毛票票。
