Spring(4)-依赖注入之Set方式注入

依赖注入：Set注入！

依赖：bean对象的创建依赖于容器！

注入：bean对象中的所有属性，由容器来注入！

【环境搭建】

1.复杂类型

package com.kuang.pojo;

public class Address {
    private String address;

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "Address{" +
                "address='" + address + ''' +
                '}';
    }
}

2.真实测试对象

package com.kuang.pojo;
import java.util.*;
public class Student {
    private String name;
    private Address address;
    private String[] books;
    private List hobbies;
    private Map card;
    private Set games;
    private String wife;
    private Properties info;
    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + ''' +
                ", address=" + address +
                ", books=" + Arrays.toString(books) +
                ", hobbies=" + hobbies +
                ", card=" + card +
                ", games=" + games +
                ", wife='" + wife + ''' +
                ", info=" + info +
                '}';
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Address getAddress() {
        return address;
    }
    public void setAddress(Address address) {
        this.address = address;
    }
    public String[] getBooks() {
        return books;
    }
    public void setBooks(String[] books) {
        this.books = books;
    }
    public List getHobbies() {
        return hobbies;
    }
    public void setHobbies(List hobbies) {
        this.hobbies = hobbies;
    }
    public Map getCard() {
        return card;
    }
    public void setCard(Map card) {
        this.card = card;
    }
    public Set getGames() {
        return games;
    }
    public void setGames(Set games) {
        this.games = games;
    }
    public String getWife() {
        return wife;
    }
    public void setWife(String wife) {
        this.wife = wife;
    }
    public Properties getInfo() {
        return info;
    }
    public void setInfo(Properties info) {
        this.info = info;
    }
}

3.beans.xml

    
        
    
    
        
        
        
        
        
        
            
                西游记
                金瓶梅
                水浒传
                红楼梦
            
        

        
            
                唱
                跳
                rap
                篮球
            
        

        
            
        

        
            
                LOL
                COC
                BOB
            
        

        

        
            
                202027520516
                男
                小罗
                123
            
        
    

4.测试类

import com.kuang.pojo.Student;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
        Student student = (Student) context.getBean("student");
        System.out.println(student.toString());
        
    }
}
