struts2简单的文件上传实现

先实现简单的上传功能，更多细节以后再添加。

首先，form要有这个属性

 enctype="multipart/form-data"

其次，设置name的值

<input type="file" name="uploadLogo">

再次，action中给出set方法

private File uploadLogo;  // 上传的文件private String uploadLogoFileName; // 文件名，如：abc.jpg、abc.gifprivate String uploadLogoContentType;  // 文件类型，如：image/jpg、image/gifpublic void setUploadLogoContentType(String uploadLogoContentType) {this.uploadLogoContentType = uploadLogoContentType;}public void setUploadLogo(File uploadLogo) {this.uploadLogo = uploadLogo;}public void setUploadLogoFileName(String uploadLogoFileName) {this.uploadLogoFileName = uploadLogoFileName;}

最后，这样这样

if (uploadLogo != null) {String realPath = ServletActionContext.getServletContext().getRealPath("/images/brand");File diskFile = new File(realPath + "//" + uploadLogoFileName);FileUtils.copyFile(uploadLogo, diskFile);brand.setLogopath("images/brand/" + uploadLogoFileName);}
