概要:
实例代码具体解释:
文件夹结构
Car.java
package com.coslay.beans.autowire;public class Car { private String brand; private double price; public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } @Override public String toString() { return "Car [brand=" + brand + ", price=" + price + "]"; } public Car(){ System.out.println("Car's Constructor..."); }}Main.java
package com.coslay.beans.scope;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.coslay.beans.autowire.Car;public class Main { public static void main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-scope.xml"); Car car = (Car) ctx.getBean("car"); Car car2 = (Car) ctx.getBean("car"); System.out.println(car == car2); }}
beans-scope.xml
而在每次请求时都创建一个新的Bean实例。并返回。
--> <bean id="car" class="com.coslay.beans.autowire.Car" scope="prototype"> <property name="brand" value="Audi"></property> <property name="price" value="300000000"></property> </bean> </beans>
