Spring项目搭建

1，新建web项目

2，导入jar包

3，编写配置文件

<?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="userDao" class="com.songyan.demo1.UserDaoImpl" ></bean>

</beans>

4，新建包

5，新建接口类

package com.songyan.demo1;

public interface UserDao {
public void say();
}

6，新建接口的实现类

package com.songyan.demo1;


public class UserDaoImpl implements UserDao{
    public void say()
    {
        System.out.println("UsdeDao say helloWord");
    }

}

7，编写测试类

package com.songyan.demo1;

import javax.xml.registry.infomodel.User;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
public static void main(String[] args) {
    //初始化容器，加载xml
    ApplicationContext application =new ClassPathXmlApplicationContext("applicationContext.xml");
    //通过容器获取javabean对象实例
    UserDao userDao=(UserDao)application.getBean("userDao");
    //调用实例的方法
    userDao.say();
}
}

8，目录
