2.添加注解


    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

        <dependency>
            <groupId>org.springframework.shell</groupId>
            <artifactId>spring-shell-starter</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>



@ShellComponent
public class MyCommands {

    @ShellMethod("Add two integers together.")
    public int add(int a, int b) {
        return a + b;
    }

    @ShellMethod("echo")
    public String echo(String msg) {
        return msg;
    }
}
