一个简单的Spring应用程序

步骤

1  新建java工程

2  Spring相关的jar包放到lib目录下

3  写一个测试bean

4  写配置文件

<?xml version="1.0" encoding="UTF-8"?>



<beans xmlns="http://www.springframework.org/schema/beans" 

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"

       default-lazy-init="true">

       

    <bean id="test" class="abc.Test"></bean>

</beans>

5  写main函数

        ApplicationContext context = new FileSystemXmlApplicationContext("classpath:config.xml");

        Test test = (Test)context.getBean("test");

        System.out.println(test.getName());
