具有带空格的多个参数的Java ProcessBuilder

我知道有很多关于从java.But执行进程时解决的问题我无法使用提供的答案解决我的问题。我想从java应用程序创建postgresql数据库备份。我用下面的代码具有带空格的多个参数的Java ProcessBuilder

 //ProcessBuilder probuilder = new ProcessBuilder(new String[]{"cmd","/c","D:/PostgreSQL 8.2/bin/pg_dump.exe","-U","usr","-i","-h","localhost","-p","5432","-F","c","-b","-f","D:/backup test/backups/test_27-1-2013_210.backup", "test"}); 
     //ProcessBuilder probuilder = new ProcessBuilder(new String[]{"cmd","/c","D:\\PostgreSQL 8.2\\bin\\pg_dump.exe","-U","usr","-i","-h","localhost","-p","5432","-F","c","-b","-f","D:\\backup test\\backups\\test_27-1-2013_210.backup", "test"}); 
     ProcessBuilder probuilder = new ProcessBuilder(new String[]{"cmd","/c","\"D:\\PostgreSQL 8.2\\bin\\pg_dump.exe\"","-U","usr","-i","-h","localhost","-p","5432","-F","c","-b","-f","\"D:\\backup test\\backups\\test_27-1-2013_210.backup\"", "test"}); 
     Map<String, String> env = probuilder.environment(); 
     env.put("PGPASSWORD", "mypass"); 

     final Process process = probuilder.start();

上面的代码执行我获得以下错误后：当路径备份文件包含空格，否则创建备份 D:\PostgreSQL' is not recognized as an internal or external command, operable program or batch file.

问题只occures。我试图在文件路径中同时使用斜杠和反斜杠，并且我引用了文件路径，但每次都收到相同的错误。命令可以从命令提示符执行。

我在做什么错。 ProcessBuilder中的空格参数数量是否有限制？谢谢

由于pg_dump.exe是一个exe文件（而不是.bat文件），所以根本不需要cmd，它可能会导致比解决问题更多的问题。请直接拨打exe，并删除文件路径附近的额外引号集：

new String[]{"D:\\PostgreSQL 8.2\\bin\\pg_dump.exe","-U","usr","-i", 
    "-h","localhost","-p","5432","-F","c","-b", 
    "-f","D:\\backup test\\backups\\test_27-1-2013_210.backup", "test"}
