本文介绍了一个使用Java实现的FastDFS客户端类，该类能够连接到FastDFS服务器并提供文件上传功能。支持从本地文件路径上传文件，也可以直接通过字节数组上传文件内容，并允许指定文件扩展名和元数据。

public class FastDFSClient {

private TrackerClient trackerClient = null;
private TrackerServer trackerServer = null;
private StorageServer storageServer = null;
private StorageClient1 storageClient = null;

public FastDFSClient(String conf) throws Exception {
if (conf.contains("classpath:")) {
conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
}
ClientGlobal.init(conf);
trackerClient = new TrackerClient();
trackerServer = trackerClient.getConnection();
storageServer = null;
storageClient = new StorageClient1(trackerServer, storageServer);
}

/**
* 上传文件方法
* Title: uploadFile
* Description: 
* @param fileName 文件全路径
* @param extName 文件扩展名，不包含（.）
* @param metas 文件扩展信息
* @return
* @throws Exception
*/
public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
String result = storageClient.upload_file1(fileName, extName, metas);
return result;
}

public String uploadFile(String fileName) throws Exception {
return uploadFile(fileName, null, null);
}

public String uploadFile(String fileName, String extName) throws Exception {
return uploadFile(fileName, extName, null);
}

/**
* 上传文件方法
* Title: uploadFile
* Description: 
* @param fileContent 文件的内容，字节数组
* @param extName 文件扩展名
* @param metas 文件扩展信息
* @return
* @throws Exception
*/
public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {

String result = storageClient.upload_file1(fileContent, extName, metas);
return result;
}

public String uploadFile(byte[] fileContent) throws Exception {
return uploadFile(fileContent, null, null);
}

public String uploadFile(byte[] fileContent, String extName) throws Exception {
return uploadFile(fileContent, extName, null);
}
}
