Spring属性注入

通过spring的属性注入解决如下问题 ：

1、

创建一个学生类，包括姓名、性别属性。

创建一个浴池管理人员，其中有一个方法，对一组学生进行检查，如果是男生，可以进入浴池洗浴，如果是女生，不能进入浴池。

现有如下学生  

张三   男  

李四   男

王五   女

赵六   男

请管理人员输出，最后检查结果

package com.xzit.model;

//学生类
public class Student {
    private String name;
    private String sex;

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

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

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

package com.xzit.model;

import java.util.Set;

//泳池管理员类
public class Manager {
    private String name;
    private Set<Student> student;

    public String getName() {
        return name;
    }

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

    public Set<Student> getStudent() {
        return student;
    }

    public void setStudent(Set<Student> student) {
        this.student = student;
    }

    public void checkStudent(){
        Set<Student> students = this.getStudent();
        for (Student student : students){
            if (student.getSex().equals("男")){
                System.out.println(name+"允许"+student.getName()+"进入泳池");
            }else{
                System.out.println(name+"不允许"+student.getName()+"进入泳池");
            }
        }
    }

    @Override
    public String toString() {
        return "Manager{" +
                "name='" + name + '\'' +
                ", student=" + student +
                '}';
    }
}
