Java - 带有空格和双引号的 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运行上述命令，它工作正常。

如果我随后将命令和参数发出为 String [] 数组，如以下 StackOverflow 帖子（ProcessBuilder 在命令行中添加额外的引号）所示，则会失败，因为目录路径中的空格以某种方式破坏了 CCBU.exe 可执行文件的参数:

[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，则效果很好：

"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。所以我必须以某种方式让它与空格一起工作。我认为这很简单，但我错过了什么？

我正在使用这篇文章中的类来处理 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，最终有效的代码：

            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() );

我所要做的就是取出所有双引号并让 ProcessBuilder 自己处理目录路径......

添加不带“双”引号的单个字符串。

\n\n

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

ProcessBuilder 将负责对参数进行必要的处理。

Jayan，你的想法让我思考：以下方法有效：

\n\n

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