导入

public static void load() {try {String fPath = "备份的文件路径名";Runtime rt = Runtime.getRuntime();Process child = rt.exec("mysql -u用户名 -p密码 数据库名");OutputStream out = child.getOutputStream();String inStr;StringBuffer sb = new StringBuffer("");String outStr;BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(fPath), "utf8"));while ((inStr = br.readLine()) != null) {sb.append(inStr + "\r\n");}outStr = sb.toString();OutputStreamWriter writer = new OutputStreamWriter(out, "utf8");writer.write(outStr);writer.flush();out.close();br.close();writer.close();} catch (Exception e) {e.printStackTrace();}}
