spring05配置文件之间的关系

一：配置文件包含关系

1.创建对应的实体类

public class Student {   //学生实体类

    private  String   name;  //姓名
    private  Integer  age;  //年龄
    private  Grade   grade;  //年级

    @Override
    public String toString() {
        return "Student [name=" + name + ", age=" + age + ", grade=" + grade
                + "]";
    }
    
    public Student() {
        super();
    }
    public Student(String name, Integer age, Grade grade) {
        super();
        this.name = name;
        this.age = age;
        this.grade = grade;
    }
    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 Grade getGrade() {
        return grade;
    }
    public void setGrade(Grade grade) {
        this.grade = grade;
    }
}
