FASTDFS安装（四）JAVA API

1.fdfs_client.conf

tracker_server = 192.168.117.100:22122

2.FDFSTest.java 

package com.siyuan.fastdfs;

import java.io.File;

import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient;

public class FDFSTest {
	
	private static String CONF_PATH = null;
	static {
		String classPath;
		try {
			classPath = new File(FDFSTest.class.getResource("/").getFile()).getCanonicalPath();
			CONF_PATH = classPath + File.separator + "fdfs_client.conf";  
			ClientGlobal.init(CONF_PATH);
		} catch (Exception e) {
			System.out.println("fail to init fastdfs configuration " + e);
			e.printStackTrace();
		}  
	}
	
	public static void main(String[] args) throws Exception {
        StorageClient storageClient = new StorageClient();
        
        // 文件上传
        NameValuePair[] meta_list = new NameValuePair[1];  
        meta_list[0] = new NameValuePair("originalName", "fdfs_client.conf");  
        String fileIds[] = storageClient.upload_file(CONF_PATH, null, meta_list);
        
        System.out.println(fileIds[0]);
        System.out.println(fileIds[1]);
        
        // 文件删除
        storageClient.delete_file(fileIds[0], fileIds[1]);
	}

}

 建议：

1）fdfs_client.conf中配置多个tracker_server

2）使用无参构造构建StorageClient

原因：

每次操作都重新获取可用的TrackerServer并从中获取可用的StorageServer，使用实现HA

缺点：

每次请求都浪费几次请求
