一、基于xml的装配
Student.java
package com.yh; public class Student implements People public void breath() System.out.println("呼吸");
XML配置
<?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" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <bean id="student" class="com.yh.Student"></bean> </beans>
测试
@Test public void demo01() String xmlPath = "applicationContext.xml"; ApplicationContext context = new ClassPathXmlApplicationContext(xmlPath); Student stu = (Student) context.getBean("student"); stu.breath();
二、基于Annotation(注解)的装配
Student,java
package com.yh; import org.springframework.stereotype.Component; @Component public class Student implements People public void breath() System.out.println("呼吸");
XML配置
<?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" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <context:component-scan base-package="com.yh"></context:component-scan> </beans>
测试
@Test public void demo01() String xmlPath = "applicationContext.xml"; ApplicationContext context = new ClassPathXmlApplicationContext(xmlPath); Student stu = (Student) context.getBean("student"); stu.breath();
