由于使用nohup，“Bad File Descriptor”异常

Question

My application can be launched via Terminal in linux OS as shell executable file. I have no issues while executing it normally, however when i execute it along with 'nohup' command , it logs below exception in 'nohup.out' file

`Exception in thread "Spring Shell" java.lang.IllegalStateException: Shell line reading failure

Now, as per my analysis, my application is based on spring shell and it tries to open/access the Terminal/Console initially while executing the application. But as nohup is used , standard input is redirected from /dev/null and hence my application tries to open/access /dev/null as Terminal and hence i get above exception.

Please can someone point me whether i am going in correct direction or not? and also is there any alternative for nohup command?

你可以尝试这样的事情：

nohup java -jar shell-app.jar 'spring shell command' > log.log 2>&1
