[英]How to start a process from Java with arguments which contain double-quotes
[英]Java - ProcessBuilder command arguments with spaces and double-quotes fails
我正在使用 ProcessBuilder 運行 Windows 可執行文件...我需要運行的確切命令是:
"C:\Program Files\CCBU\CCBU.exe" -d"C:\My Data\projects\ccbu\ciccb-report.xls" -tf"C:\Program Files\CCBU\loss-billing-filters.txt"
如果我從命令提示符運行上述命令,它工作正常。
然后,如果我按照以下 StackOverflow 帖子( ProcessBuilder 在命令行中添加額外的引號)中指示的命令和參數作為 String [] 數組發出命令和參數,它會失敗,因為目錄路徑中的空格會以某種方式將參數破壞為 CCBU.exe 可執行文件:
[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]
如果我將數據文件和過濾器移動到沒有空格的目錄路徑,這可以正常工作:
"C:\Program Files\CCBU\CCBU.exe" -d"C:\Users\n0002501\ccbu\ciccb-report.xls" -tf"C:\Users\n0002501\ccbu\loss-billing-filters.txt"
問題是,這個過程的用戶將把文件放在有空格的文件夾(目錄)中。 所以不知何故,我必須讓它與空間一起工作。 我在想這很簡單,但我錯過了什么?
我正在使用此帖子中的類來處理 STDOUT 和 STDERR 的線程:http: //alvinalexander.com/java/java-exec-processbuilder-process-2
這是代碼:
// 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,最終有效的代碼:
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() );
我所要做的就是去掉所有的雙引號,讓 ProcessBuilder 自己處理目錄路徑......
蒂亞,阿迪姆
添加不帶“雙”引號的單個字符串..
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 將負責對 args 進行必要的處理。
拉起評論:
Jayan,你的想法讓我思考:以下工作:
commands.add ( "-dC:\\My Data\\projects\\ccbu\\ciccb-report.xls" ); commands.add ( "-tfC:\\Program Files\\CCBU\\loss-billing-filters.txt"
); – 林肯
