Rhythmk 一步一步学 JAVA (12) Spring-1 之入门

（一）简单对象Spring XML配置说明

使用Spring (Spring 3.0) 实现最简单的类映射以及引用,属性赋值：

1.1、新建类UserModel：

package com.spring.ioc_1;

/*rhythmk.cnblogs.com*/

public class UserModel {

	public int getAge() {

		return Age;

	}

	public void setAge(int age) {

		Age = age;

	}

	public String getName() {

		return Name;

	}

	public void setName(String name) {

		Name = name;

	}

	private int Age;

	private String  Name;

	private Apple apple;

	public Apple getApple() {

		return apple;

	}

	public void setApple(Apple apple) {

		this.apple = apple;

	}

	public void Info()

	{

		System.out.println(String.format("我的姓名是%s,我的年纪是%s",this.Name,this.Age ));

	}

	public void Say(String msg)

	{

		System.out.println(String.format("“%s”说：%s!",this.Name,msg));

	}

	public void Eat()

	{

		System.out.println(String.format("“%s”正在吃%s的苹果!",this.Name,this.apple.getColor()));

	}

}

　　Apple 类：

package com.spring.ioc_1;

public class Apple {

	private String Color;

	public String getColor() {

		return Color;

	}

	public void setColor(String color) {

		Color = color;

	}

}

1.2、Spring配置文件：

one.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

      http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <bean id="apple" class="com.spring.ioc_1.Apple">

    <!-- 通过 property-Name 以及 value  映射对应的setPropretyName方法 赋值  -->

    <property name="Color" value="红色"></property>

    </bean>

    <bean  id="userModel" class="com.spring.ioc_1.UserModel">

      <property name="Age" > <value> 12</value></property>

      <property name="Name"><value>rhythmk</value> </property>

      <!-- ref 引用对应的 指定 id 的bean -->

      <property name="Apple" ref="apple"></property>

    </bean>

</beans>

1.3、调用

@Test

    public void UserSay()

    {

        BeanFactory factory = new ClassPathXmlApplicationContext("one.xml");

        UserModel userModel = (UserModel) factory

                .getBean("userModel");

        userModel.Say("Hello");

        userModel.Info();

        userModel.Eat();

    }

输出：

“rhythmk”说：Hello!
我的姓名是rhythmk,我的年纪是12
“rhythmk”正在吃红色的苹果!

（二）Map,Set,List,Properties XML配置说明

2.1、Order 类

package com.spring.ioc_1;

import java.util.List;

import java.util.Map;

import java.util.Properties;

import java.util.Set;

public class Order {

    // 商品集合

    private Map goods;

    public Map getGoods() {

        return goods;

    }

    public void setGoods(Map goods) {

        this.goods = goods;

    }

    public Set getGoodsType() {

        return goodsType;

    }

    public void setGoodsType(Set goodsType) {

        this.goodsType = goodsType;

    }

    public List getOrderType() {

        return orderType;

    }

    public void setOrderType(List orderType) {

        this.orderType = orderType;

    }

    public Properties getPrice() {

        return price;

    }

    public void setPrice(Properties price) {

        this.price = price;

    }

    // 包括物品种类

    private Set goodsType;

    // 订单类型

    private List orderType;

    //  物品价格

    private Properties price;

    public void Show()

    {

        System.out.println("订单创建完成：");

                // **  输出属性******

    }

}

2.2、属性配置 :Two.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

      http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <bean id="Order" class="com.spring.ioc_1.Order">

        <property name="goods">

            <map>

                <entry key="0001">

                    <value>啤酒</value>

                </entry>

                <entry key="0002">

                    <value>电脑</value>

                </entry>

            </map>

        </property>

        <property name="goodsType">

            <set>

                <value>虚拟订单</value>

                <value>百货</value>

                <value>图书</value>

            </set>

        </property>

        <property name="price">

            <props>

                <prop key="pj001">2.3</prop>

                <prop key="dn001">1232.3</prop>

            </props>

        </property>

        <property name="orderType">

            <list>

                <value>虚拟货物</value>

                <value>生活用品</value>

                <value>书</value>

            </list>

        </property>

    </bean>

</beans>

调用：

 @Test

    public void Order()

    {

    	BeanFactory factory = new ClassPathXmlApplicationContext("two.xml");

    	Order order = (Order) factory

				.getBean("Order");

    	order.Show();

    }
