一、新建项目，添加spring的相关jar包等
二、创建相关类以及属性和方法
Student.java
package com.yh; public class Student implements People { private Course course; @Override public void breath() { // TODO Auto-generated method stub System.out.println("呼吸"); } public Course getCourse() { return course; } public void setCourse(Course course) { this.course = course; } }
三、配置xml文件
自动装配方法一：设置autowire（这里为byName）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd"> <bean id="student" class="com.yh.Student" autowire="byName"></bean> <bean id="course" class="com.yh.Course"></bean> </beans>
装配方法：Student类的成员变量名对应bean的id。
自动装配方法二：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd"> <bean id="student" class="com.yh.Student"> <property name="course" ref="course"></property> </bean> <bean id="course" class="com.yh.Course"></bean> </beans>
装配方法：name对应Student类中名为course的成员变量，ref对应当前xml文件中id为course的bean。
四、编写测试类
package com.yh; import org.junit.*; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringDemoTest { @Test public void demo01(){ String xmlPath="applicationContext.xml"; ApplicationContext context = new ClassPathXmlApplicationContext(xmlPath); Student stu = (Student)context.getBean("student"); stu.breath(); stu.getCourse().showCourse(); } }
