带有空格和双引号的Java - ProcessBuilder命令参数失败。
带有空格和双引号的Java - ProcessBuilder命令参数失败。
提问于 2015-08-31 15:22:11
我正在使用ProcessBuilder运行一个Windows executable...the确切的命令，我需要运行的是：
"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中运行上面的命令，它就能正常工作。
如果然后以字符串[]数组的形式发出命令和参数，如下面的StackOverflow post (ProcessBuilder adds extra quotes to command line)所示，则会失败，因为目录路径中的空格会将参数以某种方式中断到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中，则工作正常：
"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，此过程的用户将把文件放在有空格的文件夹(目录)中。所以我得让它和空间一起工作。我想这很简单，但我错过了什么？
我使用本文中的类来处理STDOUT和STDERR：http://alvinalexander.com/java/java-exec-processbuilder-process-2的线程
下面是代码：
// 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，工作的最终代码：
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() );我所要做的就是取出所有双引号，让ProcessBuilder自己处理目录路径.

添加没有“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将负责对args的必要处理。
拉出评论：
贾扬，你的想法让我思考:以下几点奏效了： commands.add ( "-dC:\My Data\projects\ccbu\ciccb-report.xls“)；commands.add ( "-tfC:\Program Files\CCBU\loss-tfC：\Program-filters.txt”) - lincolnadym
