有从服务器上直接把文件导出到本地路径，自然也可以从本地路径中直接读取文件。 好像只要取得远程的本地路径，然后用java类中读取文件的类读这个文件就行了。 FileInputStream ofi = new FileInputStream(文件路径+文件名); InputStreamReader in = new InputStreamReader(ofi, "GBK"); BufferedReader oBufReader = new BufferedReader(in); 然后用readLine()方法逐行读取了。 至于写入数据库，只要把读取的内容按你需要拆分开来，insert到数据库就行了。
