【SpringBoot学习笔记】使用xml配置容器

首先创建所需要的类：

package com.blushyes.vo;

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

    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

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

然后在resources文件夹下创建xml文件“beans.xml”，并添加Bean：

从容器中提取对象：

String config = "beans.xml";	//指定config文件
ApplicationContext context = new ClassPathXmApplicationContext(config);	//由config文件创建容器
Student student = (Student) context.getBean("myStudent");	//从容器中取得对象
System.out.println(student);

输出：

Student{name=‘张三’, age=19, sex=‘男’}
