Spring阶段性学习总结（二）构造器的方式填充Bean

package SpringBeanDeploy;

public class Student {
    private  String name;
    private  int age;
    private  String sex;

    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public Student(String name, int age, String sex) {
        this.name = name;
        this.age = age;
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }
}

 

package SpringBeanDeploy;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("SpringBeanDeploy/SpringapplicationContext.xml");
        Student student = (Student) applicationContext.getBean("Student");
        System.out.println(student);
        student = (Student) applicationContext.getBean("Student1");
        System.out.println(student);
    }
}
