篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring 配置和集成相关的知识，希望对你有一定的参考价值。

1 创建web工程

使用eclipse创建一个web工程，加入工程修改为支持web3.1，具体的步骤将看到我发表
maven安装配置

2 spring配置

spring配置文件

spring-bean.xml

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

</beans>

<bean id="demo" class="org.lisen.springdemo.model.Demo">
		<property name="name">
			<value>张三</value>
		</property>
	</bean>

配置文件说明：
属性：

id：在容器中查找Bean的id(唯一、且不能以/开头)
class：bean的完整类名
name：在容器中查找Bean的名字(唯一、允许以/开头、允许多个值，多个值之间用逗号或空格隔开)
scope:(singleton|prototype)默认是singleton
singleton: 单例模式, 在每个Spring IoC容器中一个bean定义对应一个对象实例
prototype：原型模式/多例模式, 一个bean定义对应多个对象实例
parent：指定一个父bean(必须要有继承关系才行)
abstract: 将一个bean定义成抽象bean(抽象bean是不能实例化的),抽象类一定要定义成抽象bean,非抽象类也可以定义成抽象bean
init-method=“init” 初始化调用对象的init方法
ref 引用
