Java – spring boot remote shell custom command

I tried to add a new custom command to the spring boot remote shell, but failed

http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-remote-shell.html I also looked at the crash document: http://www.crashub.org/1.3/reference.html#_java_commands

I put my classes in package commands and crash Commands, but if I connect to the shell via SSH and type help, I won't see my new command You know what I did wrong?

This is my java code:

package commands;

import org.crsh.cli.Command;
import org.crsh.cli.Usage;
import org.crsh.command.BaseCommand;
import org.springframework.stereotype.Component;

@Component
public class hello extends BaseCommand {

  @Command
  @Usage("Say Hello")
  public String test() {
    return "HELLO";
  }
}

Solution

If your class is called 'hello', please put it in

resources/crash/commands/hello/hello.java

Package statements do not matter You don't have to put anything in SRC, just in internal resources

@Component is not required

This class is compiled at run time See:

org.crsh.lang.impl.java.JavaCompiler#compileCommand

Therefore, delayed initialization is needed to consider any dependency injection requirements
