浏览数：22 / 时间：2015年06月12日

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");

try {

String name = sdf.format(new Date());
String filePath = System.getProperty("user.dir") + "//" + name + ".sql";

// 系统执行器
Runtime rt = Runtime.getRuntime();

// 导出数据库语句
StringBuffer cmd = new StringBuffer();
cmd.append("mysqldump -u");
cmd.append(ServeConfig.dbUser);
cmd.append(" -p");
cmd.append(ServeConfig.dbPass);
cmd.append(" --set-charset=utf8 ");
cmd.append(ServeConfig.dbName);

// 执行导出获取输入流
Process child = rt.exec(cmd.toString());
InputStream in = child.getInputStream();
InputStreamReader ir = new InputStreamReader(in, "utf8");

// 输出文件
FileOutputStream fo = new FileOutputStream(filePath);
OutputStreamWriter os = new OutputStreamWriter(fo, "utf8");

// 开始读取数据
char[] temp = new char[1024000];
int len = 0;
while ((len = ir.read(temp)) > 0) {
os.write(temp, 0, len);
os.flush();
}

// 别忘记关闭输入输出流
in.close();
ir.close();
os.close();
fo.close();

// 将文件发送到备份服务器
FileUpLoad upload = FileUpLoad.createFileUpLoad(ServeConfig.backAddr, new File(filePath));
upload.tryStart();
upload.waitFinish();
upload.doClose();

} catch (Exception e) {
e.printStackTrace();
}
