Run the date command in Spring Shell (“Cannot run program … the system cannot find the file specified”)

Question

As per the documentation which says

OsCommands - the keyword for this command is the exclamation point, after the exclamation point you can pass in a Unix/windows command string to be executed

This means, we can execute OS commands in Spring Shell by prefixing the OS command with ! (exclamation).

But I believe there is some issue or I am missing something. When I tried, I got the below error.

hw-shell>! date
command is: date
Unable to execute command date [Cannot run program "date" (in directory "."): CreateProcess error=2, The system cannot find the file specified]

Answer 1

I thinks you may be forgot to set class path in your spring shell class,Set the class path using below line then try...

new ClassPathXmlApplicationContext("classpath*:/META-INF/spring/spring-shell-plugin.xml");

根据异常消息的缺失，您是否在Windows的％PATH％环境中真正拥有了“日期”命令。

Answer 3

"date" is a built-in command of the windows command shell. It seems that these built-in commands are not available within spring-shell and spring-shell looks after commands which exist real as file in the windows path.

Windows-Commands like calc ( ! calc ) which are not built-in are available.
