JavaEE框架整合开发入门到实战：Spring+SpringMVC+MyBAtis(微课版）——代码练习第一章

纯手敲，谢谢支持

	使用eclipse编写，工程目录结构如下：

第一单元

目录结构

其中使用的Spring核心jar放在WEB-INF的lib目录下

TestDao.java

package dao;

public interface TestDao {
	public void sayHello();
}

TestDaoImpl.java

package dao;

public class TestDaoImpl implements TestDao {

	@Override
	public void sayHello() {
		// TODO Auto-generated method stub
        System.out.println("Hello,Study hard!");
	}

}

Test.java

package 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.context.support.FileSystemXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;

import dao.TestDao;

public class test {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		/*初始化Spring容器，加载配置文件
		   BeanFactory工厂
		  BeanFactory beanFac=new XmlBeanFactory(new FileSystemResource("C:\\Users\\gao\\Desktop\\Spring环境搭建\\ch1\\src\\applicationContext.xml"));      
		   TestDao tt=(TestDao)beanFac.getBean("test");
		 */
			 
		//ApplicationContext appCon=new ClassPathXmlApplicationContext("applicationContext.xml");
        //TestDao tt=(TestDao)appCon.getBean("test");
		ApplicationContext appcon=
				new FileSystemXmlApplicationContext("C:\\\\Users\\\\gao\\\\Desktop\\\\Spring环境搭建\\\\ch1\\\\src\\\\applicationContext.xml");
		TestDao tt=(TestDao)appcon.getBean("test");
		tt.sayHello();
	}
}

application.xml

package 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.context.support.FileSystemXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;

import dao.TestDao;

public class test {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		/*初始化Spring容器，加载配置文件
		   BeanFactory工厂
		  BeanFactory beanFac=new XmlBeanFactory(new FileSystemResource("C:\\Users\\gao\\Desktop\\Spring环境搭建\\ch1\\src\\applicationContext.xml"));      
		   TestDao tt=(TestDao)beanFac.getBean("test");
		 */
			 
		//ApplicationContext appCon=new ClassPathXmlApplicationContext("applicationContext.xml");
        //TestDao tt=(TestDao)appCon.getBean("test");
		ApplicationContext appcon=
				new FileSystemXmlApplicationContext("C:\\\\Users\\\\gao\\\\Desktop\\\\Spring环境搭建\\\\ch1\\\\src\\\\applicationContext.xml");
		TestDao tt=(TestDao)appcon.getBean("test");
		tt.sayHello();
	}
}

web.xml
