之前有说道搭建fastdfs作为图片服务器，但是没有说明如何真正在代码里调用，那么今天大致讲一下，如何使用java客户端进行上传
首先你得要有一个客户端，导入到eclipse中即可
git地址如下：
https://github.com/leechenxiang/fastdfs-client-java
js:
$(function () { $('#fileupload').fileupload({ dataType: 'json', done: function (e, data) { console.log(data); if (data.result.status != "200") { alert(data.result.msg); } else { $.each(data.result.data, function (index, file) { $("#lee").html("<a href='" + file.url + "' target='_blank'><img src='" + file.url + "' width='80' hight='80'></img></a>"); $("#picUrl").attr("value", file.urlDB); }); } }, progressall: function (e, data) { var progress = parseInt(data.loaded / data.total * 100, 10); $('#progress .bar').css( 'width', progress + '%' ); }, dropZone: $('#dropzone') }); });
html:
<input id="fileupload" type="file" name="files[]" data-url="/file/upload.action" multiple> <div id="dropzone" class="fade well">Drop files here</div> <div id="progress" class="progress"> <div class="bar" style="width: 0%;"></div> </div> <div id="lee"></div>
controller:
@RequestMapping(value="/upload", method = RequestMethod.POST) @ResponseBody public LeeJSONResult upload(MultipartHttpServletRequest request, HttpServletResponse response) throws Exception { List<PictureResult> picList = new ArrayList<PictureResult>(); Iterator<String> itr = request.getFileNames(); MultipartFile mpf = null; while (itr.hasNext()) { mpf = request.getFile(itr.next()); PictureResult pic = pictureService.uploadPic(mpf); picList.add(pic); } return LeeJSONResult.ok(picList); }
service:
@Value("${IMAGE_SERVER_BASE_URL}")
private String IMAGE_SERVER_BASE_URL;
@Value("${SERVER_PATH}")
private String SERVER_PATH;
@Override
public PictureResult uploadPic(MultipartFile picFile) {
PictureResult result = new PictureResult();
// 判断图片是否为空
if (picFile.isEmpty()) {
result.setError(YesOrNo.YES.value);
result.setMessage("图片为空");
return result;
}
// 上传到图片服务器
try {
// 取图片扩展名
String originalFilename = picFile.getOriginalFilename();
// 取扩展名不要“.”
String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
FastDFSClient client = new FastDFSClient("classpath:resource/client.conf");
String url = client.uploadFile(picFile.getBytes(), extName);
// 把url响应给客户端
result.setError(YesOrNo.NO.value);
result.setUrlDB(url);
result.setUrl(IMAGE_SERVER_BASE_URL + url);
} catch (Exception e) {
e.printStackTrace();
result.setError(YesOrNo.YES.value);
result.setMessage("图片上传失败");
}
return result;
}
最后配置：
tracker_server=192.168.1.188:22122
