Java-带空格和双引号的ProcessBuilder命令参数失败

Question

我正在使用ProcessBuilder运行Windows可执行文件…我需要运行的确切命令是：

"C:\Program Files\CCBU\CCBU.exe" -d"C:\My Data\projects\ccbu\ciccb-report.xls" -tf"C:\Program Files\CCBU\loss-billing-filters.txt"

如果我从命令提示符处运行上述命令，它将正常工作。

然后，如果我按照下面的帖子（ProcessBuilder在命令行中添加额外的引号）中的String
[]数组的形式发出命令和参数，则它将失败，因为目录路径中的空格以某种方式将参数打断到CCBU.exe可执行文件：

[log-snippet]
2015-08-31 10:39:08,937 [main] INFO  rpd.primary - C:\Program Files\CCBU\CCBU.exe
logging to the given report's directory
Configuration file is: ./CCBUConfigFile.txt
Running with the following settings:
Report Filepath:       C:\My
Search Terms FilePath: C:\Program

2015-08-31 10:39:08,948 [main] INFO  rpd.primary - STDERR:--------------------
2015-08-31 10:39:08,961 [main] INFO  rpd.primary - 
Warning: parameter Data\projects\ccbu\ciccb-report.xls not recognized. Ignoring

Warning: parameter Files\CCBU\loss-billing-filters.txt not recognized. Ignoring

Error: C:\Program not found or not readable
[/log-snippet]

如果我将数据文件和过滤器移动到没有空格的目录路径，则可以正常工作：

"C:\Program Files\CCBU\CCBU.exe" -d"C:\Users\n0002501\ccbu\ciccb-report.xls" -tf"C:\Users\n0002501\ccbu\loss-billing-filters.txt"

问题是，此过程的用户将文件放置在确实有空格的文件夹（目录）中。因此，我必须以某种方式使其与空间配合使用。我想这很简单，但是我想念的是什么？

我正在使用本文中的类来处理STDOUT和STDERR的线程：http : //alvinalexander.com/java/java-exec-
processbuilder-process-2

这是代码：

            // Split the Arguments : 
            // In Eclipse and runtime, the arguments get broken : 
            // The STDOUT from the command shows the Report Filepath
            // and Search Teams FilePath as broken at the 1st space...
            // 
            // Report Filepath:       C:\My
            // Search Terms FilePath: C:\Program
            // 
            // SHOULD BE : 
            // 
            // Report Filepath:       C:\My Data\projects\ccbu\ciccb-report.xls
            // Search Terms FilePath: C:\Program Files\CCBU\loss-billing-filters.txt
            // 
            try { 
                commands.add ( "\"C:\\Program Files\\CCBU\\CCBU.exe\""                      );
                commands.add ( "-d\"C:\\My Data\\projects\\ccbu\\ciccb-report.xls\""        );
                commands.add ( "-tf\"C:\\Program Files\\CCBU\\loss-billing-filters.txt\""   );
                commandExecutor = new SystemCommandExecutor(commands);
                commandExecutor.setLog ( getLog() );

                // DEBUG : Build and printout the commands...
                // 
                lstrCommand = "";
                for ( int theIdx=0; theIdx<commands.size (); theIdx++ ) {
                    if ( theIdx == 0 ) { 
                        lstrCommand = lstrCommand + commands.get ( theIdx );
                    }
                    else { 
                        lstrCommand = lstrCommand + " " + commands.get ( theIdx );
                    }
                    getLog().debug ( SHORT_NAME + " Building Command[] [" + commands.get ( theIdx ) + "]" );
                }

                getLog().debug ( SHORT_NAME + " Running Command[] [" + lstrCommand + "]" );

                result = commandExecutor.executeCommand();

                // get the stdout and stderr from the command that was run
                stdout = commandExecutor.getStandardOutputFromCommand();
                stderr = commandExecutor.getStandardErrorFromCommand();

                // print the stdout and stderr
                getLog().info ( "SystemCommandExecutor - Status Code [" + result + "]" );
                getLog().info ( "STDOUT:--------------------" );
                getLog().info( stdout );
                getLog().info ( "STDERR:--------------------" );
                getLog().info( stderr );
            }
            catch ( Exception ltheXcp ) { 
                getLog().error ( SHORT_NAME + ".runTask () - Error/exception on commands [3-spaces] [" + lstrCommand + "]" );
            }
            finally { 
                commands.clear ();
                stdout = null;
                stderr = null;
                commandExecutor = null;
            }

Jayan，有效的最终代码：

            try { 
                commands.add ( "C:\\Program Files\\CCBU\\CCBU.exe"                      );
                commands.add ( "-dC:\\My Data\\projects\\ccbu\\ciccb-report.xls"        );
                commands.add ( "-tfC:\\Program Files\\CCBU\\loss-billing-filters.txt"   );

                commandExecutor = new SystemCommandExecutor ( commands );
                commandExecutor.setLog ( getLog() );

我要做的就是取出所有双引号，让ProcessBuilder自己处理目录路径…

添加不带双引号的单个字符串。

                commands.add ( "C:\\Program Files\\CCBU\\CCBU.exe"                      );
                commands.add ( "-d");
                commands.add ("C:\\My Data\\projects\\ccbu\\ciccb-report.xls"        );
                commands.add ( "-tf");
                commands.add("C:\\Program Files\\CCBU\\loss-billing-filters.txt"   );
                commandExecutor = new SystemCommandExecutor(commands);

ProcessBuilder将处理必要的args处理。

拉起评论：

Jayan，您的主意让我开始思考：以下方法有效：

 commands.add ( "-dC:\\My Data\\projects\\ccbu\\ciccb-report.xls" );
 commands.add ( "-tfC:\\Program Files\\CCBU\\loss-billing-filters.txt"
