相关疑难解决方法(0)

我正处于将简单的java项目转换为spring引导变体的过程中.Spring引用参考指南http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/一般都非常有用,但是大多数设置简单配置的例子都涉及一些基于Web的应用程序.来自https://spring.io/guides/gs/spring-boot/教程的入门教程没有提供我正在寻找的答案.

我有一个类HelloSpring需要运行一个方法printHello().为了简单起见,我已经配置了以下类,放在同一个包中:

Application.class

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

HelloConfiguration.class

@Configuration
public class HelloConfiguration {

    @Bean
    public HelloSpring helloSpring(){
        HelloSpring hs = new HelloSpring();
        hs.printHello();
        hs.printHelloAgain();
        return hs;
    }

    @Autowired
    public HelloSpring hs;

}

HelloSpring.class

public class HelloSpring {

    public void printHello() {
        System.out.println("Hello Spring!");
    }

    @PostConstruct
    public void printHelloAgain() {
        System.out.println("Hello Spring?");
    }

}

它打印(省略弹簧记录):

Hello Spring!
Hello Spring?
Hello Spring?

但是,我不确定执行HelloSpring类的正确方法. …
