HttpClient 学习整理

先利用上传文件组件，把要上传的文件存入到一个临时路径，然后把临时路径的传递到uploadSingle(String sourceFile, String appId)方法中
/注：String 类型的sourceFile就是传的临时路径，appId是上传到服务器区域的唯一标示

// 临时保存上传的附件public void saveMediaData(FileUploadEvent event) {MediaStoreConfiguration msc = AirScapeApplicationContext.getBean("MediaStoreConfig", MediaStoreConfiguration.class);//String module = msc.getValue("ms.emall.module.global");System.out.println(event.getFile().getFileName());String filename = event.getFile().getFileName();String surffix = "." + FilenameUtils.getExtension(filename);//String mtype = event.getFile().getContentType();if (mediaService.ifMediaDataExists(MallConstant.EMALL_APP_ID, filename)){FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO, "File Exists!" + filename, ""));return;}File file;String url;String tmpName = String.valueOf(System.currentTimeMillis());try {file = File.createTempFile(tmpName,surffix);//创建一个文件默认存到临时目录下的FileUtils.copyInputStreamToFile(event.getFile().getInputstream(),file);//把要上传的文件存入到file文件中log.debug(file.getAbsolutePath());log.debug(file.getName());url = MediaKit.uploadSingle(file.getAbsolutePath(), MallConstant.EMALL_APP_ID);//上传到服务器之后，，服务器返回一个url，可以通过                        //输入浏览器地址来访问到上传到服务器的文件（各种类型）                        file.delete();//把临时文件删除//下面就是把这个文件封住成MediaData类存入到数据库中。。。。。。。。。。。。。。。。。。MediaData md = new MediaData();md.setModule(MallConstant.EMALL_APP_ID);md.setName(filename);md.setMimeType(surffix);md.setUrl(url);boolean result = mediaService.saveNewMedia(md);if (result) {FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO, "Success!" + filename, ""));} else {FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO, "Failed!" + filename,""));}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}
