具有多个带空格参数的Java ProcessBuilder

我知道有很多关于从java执行进程的问题已经解决了，但是我无法用提供的答案来解决我的问题。 我正在尝试从java应用程序创建postgresql数据库备份。我使用以下代码

        //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();

//ProcessBuilder probuilder=new ProcessBuilder（新字符串[]{“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（新字符串[]{“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\\backups\\tests\\test\U 27-1-2013\U 210.backup”、“test”}）；
ProcessBuilder probuilder=new ProcessBuilder（新字符串[]{“cmd”、“/c”、“\”D:\\PostgreSQL 8.2\\bin\\pg\U dump.exe\”、“-U”、“usr”、“-i”、“-h”、“localhost”、“-p”、“5432”、“-F”、“c”、“-b”、“-F”、“\”D:\\backup test backups\\backups\\tests\test\u27-1-2013\u210.backup\”、“test”）；
Map env=probuilder.environment（）；
环境密码（“PGPASSWORD”、“mypass”）；
最终流程=probuilder.start（）；

执行上述代码后，我得到以下错误：

D:\PostgreSQL'未被识别为内部或外部命令，
可操作的程序或批处理文件。

只有当备份文件的路径包含空格时才会出现问题，否则将创建备份。 我尝试在文件路径中使用斜杠和反斜杠，并引用了文件路径，但每次都会出现相同的错误。可以从命令提示符执行命令

我做错了什么。ProcessBuilder中带有空格的参数数量是否存在一些限制。

谢谢

因为

pg_dump.exe

是一个exe（而不是.bat），你根本不需要

cmd

，而且它可能会导致比它解决的问题更多的问题。只需直接调用

exe

，并删除文件路径周围的额外引号：

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"}
