Map依赖注入（选）

package com.hnucm.spring;

import java.util.Map;

public class Student {
    Map stuMap;

    public Map getStuMap() {
        return stuMap;
    }

    public void setStuMap(Map stuMap) {
        this.stuMap = stuMap;
    }

    @Override
    public String toString() {
        return "Student{" + "stuMap=" + stuMap + '}';
    }
}
