我有Spring-boot-starter-remote-shell的Spring Boot应用程序.当我把这个hello.groovy脚本打印出'hello'时就可以了.

package commands

import org.crsh.cli.Usage
import org.crsh.cli.Command

class hello {

    @Usage("Say Hello")
    @Command
    def main(InvocationContext context) {
        return "hello";
    }

}

但是当我尝试注入一些Spring bean时,它总是为null.

package commands

import org.crsh.cli.Usage
import org.crsh.cli.Command
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.stereotype.Component
import org.springframework.batch.core.launch.JobLauncher

@Component
class hello {
    @Autowired
    JobLauncher jobLauncher;

    @Usage("Say Hello")
    @Command
    def main(InvocationContext context) {
        if(jobLauncher != null){
            return "OK";
        }else{
            return "NULL";
        }
        return "hello j";
    }

}

我有 @ComponentScan(basePackages={"com....", "commands"})
