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
作者:互联网
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
