关于Spring

1.首先依然是导入相关的jar包�?br />2.创徏配置文�g�Q�applicationContext.xml�?br /> 2.1.导入schema�?br /> 2.2<bean id="user" class="com.lei.pojo.User">bean>

注：(x��)
1.BeanFactory和ApplicationContext的主要区别：(x��)BeanFactory延迟加蝲所有的 Bean�Q�直�?getBean()�Ҏ(gu��)��被调用的

时�?Bean才会(x��)被创建；ApplicationContext则会(x��)预蝲入单�?Bean�Q�当调用 getBean()�Ҏ(gu��)��的时候， Bean已经被创建成功�?br /> 2.配置bean的时候其中可以有id和name属性，id��h��唯一性，在��用中必须�?java 中命名变量一样去命名id的��|��但是
name属性值则没有要求。name 属性�ƈ不是必须的，当不�?name 属性时�Q�spring 容器�?x��)自动生�?name 属性倹{��那么在�?br />取该 bean的时候，name属性和class属性值相同�?br /> 3. 通过alias节点可以为bean指定一个别名，

如：(x��)<bean name="userDao" class="com.lei.dao.UserDao">bean>

写一个Hibernate�E�序的步骤：(x��)
1.导入相关jar包�?br />2.创徏持久化类�?br />3.创徏映射文�g�?nbsp;

1 xml version="1.0" encoding="UTF-8"?>
2 DOCTYPE hibernate-mapping PUBLIC
3     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
4     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
