Dog类代码;

package com.chinasofti.test2;

public class Dog {
    public int id ;
    public String name ;
    
    public void init() {
        System.out.println("初始化方法");
    }
    
    public void destroy() {
        System.out.println("销毁方法");
    }
    
    public Dog() {
        super();
        System.out.println("无参构造");
    }
    public Dog(java.lang.Integer id, java.lang.String name) {
        super();
        this.id = id;
        this.name = name;
        System.out.println("有参构造");
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "Dog [id=" + id + ", name=" + name + "]";
    }
}

Mydog类代码：

package com.chinasofti.test;

import com.chinasofti.test2.Dog;

public class Mydog {
    /*静态工厂方法
     * public static Dog getDog() {
        return new Dog(116, "小王");
    }*/
    
    //普通工厂方法
    public Dog getDog(){
        return new Dog();
    }
}

Person类代码（用于测试集合）：

package com.chinasofti.test;

import java.util.List;
import com.chinasofti.test2.Dog;

public class Person {
    
    public int id;
    public String name;
    public List<Dog> list;
    
    public Person() {
        super();
    }
    public List<Dog> getList() {
        return list;
    }
    public void setList(List<Dog> list) {
        this.list = list;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
}

 

测试类代码：

package com.chinasofti.test;

import java.util.List;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.chinasofti.test2.Dog;
public class TestSpring {
    
    @Test
    public void runnn() {
        ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("/ApplicationContext.xml");
        Dog dog = (Dog) ac.getBean("dog");
        System.out.println("dog.getName"+dog.getName());

        System.out.println(dog2);
        System.out.println(dog3);*/
        
        /*Person person = ac.getBean("person",Person.class);
        System.out.println(person.id);
        System.out.println(person.name);
        System.out.println(person.dog.id);
        System.out.println(person.dog.name);*/
        
        /*Person person = ac.getBean("person",Person.class);
        List<Dog> list =  person.getList();
        for (Dog dog : list) {
            System.out.println(dog);
        }*/
        
        ac.close();
    }
}
