使用eclipse搭建Spring框架

1.为了便于快速开发，所以我们需要下载一个spring tool工具
具体详情请参考http://blog.csdn.net/zhangkaidsy/article/details/77470908

但是和下载Hibernate Tools工具不一样的是，这次不需要去掉任何工具的勾选，默认全部勾选的就好，然后静静等待几分钟，成功后eclipse会提示是否重启，选择YES

2.重启后，在pom.xml添加Spring依赖

<dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>4.3.10.RELEASE</version>    </dependency>

如果需要添加Spring其他版本的依赖
请去Spring官网www.spring.io
或者去Maven repository自行查询Spring依赖版本

3.依赖添加成功后，在resources下新建xml

然后Finish即可

4.使用
新建HumanBody实体类

package com.zhangkai.entity;public class HumanBody {    private Hand hand;    private Foot foot;    private Renal renal;    public HumanBody(Hand hand, Foot foot, Renal renal) {        super();        this.hand = hand;        this.foot = foot;        this.renal = renal;    }    public HumanBody() {        super();    }    public Hand getHand() {        return hand;    }    public void setHand(Hand hand) {        this.hand = hand;    }    public Foot getFoot() {        return foot;    }    public void setFoot(Foot foot) {        this.foot = foot;    }    public Renal getRenal() {        return renal;    }    public void setRenal(Renal renal) {        this.renal = renal;    }    @Override    public String toString() {        return "HumanBody [hand=" + hand.getHand() + ", foot=" + foot.getFoot() + ", renal=" + renal.getRenal() + "]";    }}

在编写三个接口，在这我就只是用其中一个接口作为示例

package com.zhangkai.entity;public interface Foot {    public String getFoot();}

实现接口

package com.zhangkai.dao;import com.zhangkai.entity.Hand;public class HandRightDao implements Hand{    public String getHand() {        return "这是右手";    }}

applicationContext.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.xsd">    <bean id="HumanBody" class="com.zhangkai.entity.HumanBody"><!-- 引用实体类 -->        <property name="hand" ref="HandRightDao"></property><!-- 为实体类属性引用方法实现类  ref:方法实现类id在下方-->        <property name="foot" ref="FootLiftDao"></property>        <property name="renal" ref="RenalLiftDao"></property>    </bean>    <bean id="HandRightDao" class="com.zhangkai.dao.HandRightDao"></bean><!-- 引用方法实现类 -->    <bean id="FootLiftDao" class="com.zhangkai.dao.FootLiftDao"></bean>    <bean id="RenalLiftDao" class="com.zhangkai.dao.RenalLiftDao"></bean>    <!-- 注意：id要保持一致 --></beans>

测试：

package com.zhangkai.test;import org.junit.Test;import org.springframework.beans.factory.BeanFactory;import org.springframework.beans.factory.xml.XmlBeanFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.core.io.ClassPathResource;import com.zhangkai.entity.HumanBody;public class SpringTest {    //延时加载：解析xml时并不会加载所有bean,只会在调用bean时去加载。优缺点：服务器启动速度较快,但用户等待时间较长    public void test1(){//延时加载(懒加载)        BeanFactory bf=new XmlBeanFactory(new ClassPathResource("applicationContext.xml"));        HumanBody humanBody=(HumanBody) bf.getBean("HumanBody");        System.out.println(humanBody);    }    //即时加载：解析XMl时将所有bean全部加载,调用bean时便不会再去xml解析了。优缺点：服务器启动速度较慢,但用户等待时间较短    @Test    public void test2(){//即时加载        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");        HumanBody humanBody=(HumanBody) ac.getBean("HumanBody");        System.out.println(humanBody);    }}
