springboot的5种读取配置方式（1）：直接读取bean

1.直接读取bean：

/**
 * 学生实体类
 * Created by ASUS on 2018/5/4
 */
public class Student {
    private String name;
    private  int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

/**
 * springboot启动类
 *
 */

@SpringBootApplication
public class Application
{
    public static void main( String[] args )
    {
        ApplicationContext applicationContext= SpringApplication.run(Application.class,args);
        Student student= (Student) applicationContext.getBean("s1");
        Student student1= (Student) applicationContext.getBean("ss");
        System.out.println("message:"+student.toString());
        System.out.println("message:"+student1.toString());
        
    }

    /**
     * 声明bean，name为s1
     * @return
     */
    @Bean(name = "s1")
    public Student s1(){
        Student student=new Student("哈哈",12);
        return  student;

    }

    /**
     * 声明bean,name为ss
     * @return
     */
    @Bean(name = "ss")
    public Student ss(){
        Student student=new Student("哈哈",18);
        return  student;

    }
}

测试结果：

不过这种方式是不建议用的，因为这样要写的bean是很多，而且不好，知道下就好。

我的座右铭：不会，我可以学；落后，我可以追赶；跌倒，我可以站起来；我一定行。
