基于XML配置

Beans.xml

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"       1.默认命名空间
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        2.xsi标准命名空间,用于指定自定义命名空间的Schema文件
    xmlns:p="http://www.springframework.org/schema/p"            3.声明p命名空间
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
         http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
<bean id="car" class="com.smart.ditype.Car"                      4.id为bean的名称,可以通过getbean("car")获取容器中的Bean,class为Bean的类名
      p:brand="红旗123&amp;CA72"                                  5.采用p命名空间配置Bean属性值
      p:maxSpeed="100"
      p:price="20000.00"/>
</beans>

Car.class

package com.smart.ditype;

public class Car {
    public String brand;
    private String corp;    
    private double price;
    private int maxSpeed;

    public Car() {}    
    public Car(String brand, double price) {
        this.brand = brand;
        this.price = price;
    }    

    public Car(String brand, String corp, double price) {
        this.brand = brand;
        this.corp = corp;
        this.price = price;
    }
    public Car(String brand, String corp, int maxSpeed) {
        this.brand = brand;
        this.corp = corp;
        this.maxSpeed = maxSpeed;
    }

    public String getBrand() {
        return brand;
    }

    public void setBrand(String brand) {
        this.brand = brand;
    }

    public int getMaxSpeed() {
        return maxSpeed;
    }

    public void setMaxSpeed(int maxSpeed) {
        this.maxSpeed = maxSpeed;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }
    
    public String toString(){
        return "brand:"+brand+"/maxSpeed:"+maxSpeed+"/price:"+price;
    }

}

Test

package com.smart.ditype;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.testng.annotations.*;
import  static  org.testng.Assert.*;

public class DiTypeTest {
    public ApplicationContext factory = null;

    private static String[] CONFIG_FILES = { "com/smart/ditype/beans.xml" };

    @BeforeClass
    public void setUp() throws Exception {
        factory = new ClassPathXmlApplicationContext(CONFIG_FILES);
    }

    @Test
    public void testCar(){
        Car car = (Car)factory.getBean("car");
        assertNotNull(car);
        System.out.println(car);
    }
}
