Spring也是一个开源框架,我在学习Spring的时候,觉得最重要的几点是:IOC(控制反转)、AOP(面向切面)和容器概念。
具体的教程还请大家去看网上的视频,这里贴一个小Demo以供学习。(前提是大家把该导入的jar包都导入了)
1、Student类和Teacher类
public class Student { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } public void sayHello() { System.out.println("Hi," + name); } }
import java.util.List; public class Teacher { private List<Student> stuList; private String name; public List<Student> getStuList() { return stuList; } public void setStuList(List<Student> stuList) { this.stuList = stuList; } public String getName() { return name; } public void setName(String name) { this.name = name; } public void myStu() { System.out.println(name + " :"); for(int i = 0; i < stuList.size(); i++) System.out.println(stuList.get(i).getName()); } }
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="student_1" class="Student"> <property name="name" value="小明"> </property> </bean> <bean id="student_2" class="Student"> <property name="name" value="小凡"> </property> </bean> <bean id="teacher" class="Teacher"> <property name="name" value="崔老师"/> <property name="stuList"> <list> <ref bean= "student_1"/> <ref bean= "student_2"/> </list> </property> </bean> </beans>
import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class main { public static void main(String[] args) { // TODO Auto-generated method stub ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); Student stu = (Student) ac.getBean("student_1"); stu.sayHello(); Teacher tec = (Teacher) ac.getBean("teacher"); tec.myStu(); } }
