Mysql备份还原，cmd命令支持带空格的路径

备份代码如下：

logger.info(dbName + "开始备份!");
String cmd = "\"\" \""+dataBaseBS.getInstallPath() +"bin\\mysqldump\" -h localhost -uroot -p123456 " + dbName
    + " > \"" + uploadPath + dbName + ".sql\""; // 一定要加 -h,localhost(或是服务器IP地址)
Process process = Runtime.getRuntime().exec("cmd /c start /b " + cmd);
InputStreamReader isr = new InputStreamReader(process.getErrorStream());
LineNumberReader input = new LineNumberReader(isr);
String line;
while ((line = input.readLine()) != null) {
}
logger.info(dbName + "备份成功!");

还原代码如下：

logger.info(dbName + "开始还原!");
String cmd = "\"\" \""+dataBaseBS.getInstallPath() +"bin\\mysql\" -h localhost -uroot -p123456 " + dbName
   + " < \"" + uploadPath + dbName + ".sql\""; // 一定要加 -h,localhost(或是服务器IP地址)
Process process = Runtime.getRuntime().exec("cmd /c start /b " + cmd);
InputStreamReader isr = new InputStreamReader(process.getInputStream());
LineNumberReader input = new LineNumberReader(isr);
String line;
while ((line = input.readLine()) != null) {
}
logger.info(dbName + "还原成功!");
