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
https://github.com/happyfish100/fastdfs-client-java
编译完了打包到maven仓库中，直接用下面这个dependency
<dependency>
<groupId>org.csource</groupId>
<artifactId>fastdfs-client-java</artifactId>
<version>1.27-SNAPSHOT</version>
</dependency>
demo里面一共就引了这么几个：
<dependencies>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>org.csource</groupId>
<artifactId>fastdfs-client-java</artifactId>
<version>1.27-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
</dependencies>
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) {

public static String uploadFile(File file, String fileName, Map<String,String> metaList) {
try {
byte[] buff = IOUtils.toByteArray(new FileInputStream(file));

}

*/
public static int downloadFile(String fileId, File outFile) {

return 0;
} catch (Exception e) {

} finally {
if (fos != null) {
try {

} 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");
Map<String,String> metaList = new HashMap<String, String>();
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<String,String> metaList = FileUtilsDemo.getFileMetadata("group1/M00/00/00/wKgAyVgFk9aAB8hwAA-8Q6_7tHw351.jpg");
for (Iterator<Map.Entry<String,String>> iterator = metaList.entrySet().iterator(); iterator.hasNext();) {
Map.Entry<String,String> entry = iterator.next();
String name = entry.getKey();
String value = entry.getValue();
System.out.println(name + " = " + value );
}
}
/**

*/
@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");
}
}
配置文件：
connect_timeout = 10
network_timeout = 30
charset = UTF-8
http.tracker_http_port = 8999
http.anti_steal_token = no
http.secret_key = FastDFS1234567890

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
