Command-line Program Support

The Nop platform has built-in support for command-line programs. As long as you register a bean that implements the ICommand interface, you can invoke it directly via command-line instructions. The application will exit immediately after the command finishes.

1. Register an implementation class of the ICommand interface, with the bean name nopCommand_xxx

  <bean id="nopCommand_test" class="test.TestCommand" />

2. Invoke the corresponding command via the nop-exec command

 java -jar app.jar nop-exec --command=test --myArg=a --myArg2=123

Detailed Configuration

1. Toggle nop.core.nop-command-executor.enabled to control whether the command-line processing feature is enabled; enabled by default.

2. Pass more complex commands as files

jar -jar app.jar nop-exec --command=test.json

test.json is a JSON-formatted command file corresponding to a CommandBean object.

{
  "command": "test",
  "params": {
    "myArg1": "a",
    "myArg2": 123
  }
}

3. Execute multiple commands sequentially

java -jar app.jar nop-exec --command=test1.json --command=test2.json

Execution will be interrupted if any command returns a non-zero value.
