請注意，是通過工廠注入bean，而不是注入工廠。

例項工廠

package tang;

public class InstanceFactory {
	public Person getPerson(String name, Integer age){
		return new Person(name, age);
	}
}

靜態工廠

package tang;

public class StaticFactory {
	public static Person getPerson(String name,Integer age){
		return new Person(name,age);
	}
}
 

實體

package tang;
public class Person {
	private String name;
	private Integer age;
	public Person() {
		System.out.println("person");
	}
	public Person(String name, Integer age) {
		super();
		this.name = name;
		this.age = age;
	}

	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "Person [name=" + name + ", age=" + age + "]";
	}
	
}

Person [name=tangxiansheng, age=19, car=null]
Person [name=tangmouren, age=20, car=null]
