依赖注入_p标签方法

注意:实体,必须要有空参,全参构造方法,和setter方法

第一步:实体

public class Car {
    private String name;
    private Double price;

    public Car() {
    }

    public Car(String name, Double price) {
        this.name = name;
        this.price = price;
    }

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

    public void setPrice(Double price) {
        this.price = price;
    }

第二步:配置

<!--p标签注入-->
<bean id="car2" class="it.heima.domain.Car"
p:name="宝马" p:price="1200000"/>

第三步：测试

@Test
public void test(){
    ClassPathXmlApplicationContext applicationContext=new ClassPathXmlApplicationContext("applicationContext.xml");
    Car car = applicationContext.getBean("car2", Car.class);
    System.out.println(car);
}
