参考了这几个搭建了FastDFS文件系统
主要是fastDFS,nginx,以及在nginx中加入fastDFS模块;这里只有一台服务器,所以搭建的是单机版的。
至于java客户端的包可以自己用maven编译,分分钟的事儿
编译完了打包到maven仓库中,直接用下面这个dependency
org.csource fastdfs-client-java 1.27-SNAPSHOT
demo里面一共就引了这么几个:
commons-io commons-io 1.4 org.csource fastdfs-client-java 1.27-SNAPSHOT junit junit 4.11 test
客户端操作的Demo:
public class FileUtilsDemo { private static StorageClient1 storageClient1 = null; // 初始化FastDFS Client static { try { ClassLoader classLoader = FileUtilsDemo.class.getClassLoader(); URL resource = classLoader.getResource("fastdfs.conf"); String path = resource.getPath(); System.out.println(path); ClientGlobal.init(path); TrackerClient trackerClient = new TrackerClient(ClientGlobal.g_tracker_group); TrackerServer trackerServer = trackerClient.getConnection(); if (trackerServer == null) { throw new IllegalStateException("getConnection return null"); } StorageServer storageServer = trackerClient.getStoreStorage(trackerServer); if (storageServer == null) { throw new IllegalStateException("getStoreStorage return null"); } storageClient1 = new StorageClient1(trackerServer,storageServer); } catch (Exception e) { e.printStackTrace(); } } /** * 上传文件 * @param file 文件对象 * @param fileName 文件名 * @return */ public static String uploadFile(File file, String fileName) { return uploadFile(file,fileName,null); } /** * 上传文件 * @param file 文件对象 * @param fileName 文件名 * @param metaList 文件元数据 * @return */ public static String uploadFile(File file, String fileName, MapmetaList) { try { byte[] buff = IOUtils.toByteArray(new FileInputStream(file)); NameValuePair[] nameValuePairs = null; if (metaList != null) { nameValuePairs = new NameValuePair[metaList.size()]; int index = 0; for (Iterator > iterator = metaList.entrySet().iterator(); iterator.hasNext();) { Map.Entry entry = iterator.next(); String name = entry.getKey(); String value = entry.getValue(); nameValuePairs[index++] = new NameValuePair(name,value); } } return storageClient1.upload_file1(buff, FilenameUtils.getExtension(fileName),nameValuePairs); } catch (Exception e) { e.printStackTrace(); } return null; } /** * 获取文件元数据 * @param fileId 文件ID * @return */ public static Map getFileMetadata(String fileId) { try { NameValuePair[] metaList = storageClient1.get_metadata1(fileId); if (metaList != null) { HashMap map = new HashMap (); for (NameValuePair metaItem : metaList) { map.put(metaItem.getName(),metaItem.getValue()); } return map; } } catch (Exception e) { e.printStackTrace(); } return null; } /** * 删除文件 * @param fileId 文件ID * @return 删除失败返回-1,否则返回0 */ public static int deleteFile(String fileId) { try { return storageClient1.delete_file1(fileId); } catch (Exception e) { e.printStackTrace(); } return -1; } /** * 下载文件 * @param fileId 文件ID(上传文件成功后返回的ID) * @param outFile 文件下载保存位置 * @return */ public static int downloadFile(String fileId, File outFile) { FileOutputStream fos = null; try { byte[] content = storageClient1.download_file1(fileId); fos = new FileOutputStream(outFile); IOUtils.copy(new ByteInputStream(content, content.length),fos); return 0; } catch (Exception e) { e.printStackTrace(); } finally { if (fos != null) { try { fos.close(); } catch (IOException e) { e.printStackTrace(); } } } return -1; }}
客户端测试的Demo:
public class FastDFSClientTest { /** * 文件上传测试 */ @Test public void testUpload() { File file = new File("C:\\Users\\023b5bb5c9ea15ce4ed7034ebc003af33a87b2b8.jpg"); MapmetaList = new HashMap (); metaList.put("width","1024"); metaList.put("height","768"); metaList.put("date","20161018"); String fid = FileUtilsDemo.uploadFile(file,file.getName(), metaList); System.out.println("upload local file " + file.getPath() + " ok, fileid=" + fid); } /** * 文件下载测试 */ @Test public void testDownload() { int r = FileUtilsDemo.downloadFile("group1/M00/00/00/cjdUkFo3fXeAAvUDAAFiCZy66os105.jpg", new File("DownloadFile_fid.jpg")); System.out.println(r == 0 ? "下载成功" : "下载失败"); } /** * 获取文件元数据测试 */ @Test public void testGetFileMetadata() { Map metaList = FileUtilsDemo.getFileMetadata("group1/M00/00/00/wKgAyVgFk9aAB8hwAA-8Q6_7tHw351.jpg"); for (Iterator > iterator = metaList.entrySet().iterator(); iterator.hasNext();) { Map.Entry entry = iterator.next(); String name = entry.getKey(); String value = entry.getValue(); System.out.println(name + " = " + value ); } } /** * 文件删除测试 */ @Test public void testDelete() { int r = FileUtilsDemo.deleteFile("group1/M00/00/00/wKgAyVgFk9aAB8hwAA-8Q6_7tHw351.jpg"); System.out.println(r == 0 ? "删除成功" : "删除失败"); }}

反正我这个文件里面写了注释,然后就报错了,我就把注释删除了就好了。一套下来接近2个小时可以搞定,搞不定问我,哈哈
