如下代码中的Student类，有基础类型，数组类型，列表类型，字典类型，该如何进行依赖注入呢

package com.loubin.pojo;

import java.util.Arrays;
import java.util.List;
import java.util.Map;

public class Student {
    private int id;
    private String name;
    private String[] books;
    private List<Cat> cats;
    private Map<String, Dog> dogs;

    public int getId() {
        return id;
    }

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", books=" + Arrays.toString(books) +
                ", cats=" + cats +
                ", dogs=" + dogs +
                '}';
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public String[] getBooks() {
        return books;
    }

    public void setBooks(String[] books) {
        this.books = books;
    }

    public List<Cat> getCats() {
        return cats;
    }

    public void setCats(List<Cat> cats) {
        this.cats = cats;
    }

    public Map<String, Dog> getDogs() {
        return dogs;
    }

    public void setDogs(Map<String, Dog> dogs) {
        this.dogs = dogs;
    }
}

 

注入方式如下所示
