12、(知識篇)Spring使用xml配置bean01

//Spring IOC - Inversion of Control（控制反轉）
//DI Dependency Injection 依賴注入
//XML版表現形式

//1、property形式：<property name="equirementNaame" value="盔甲"></property>
//2、constructor形式：<constructor-arg name="attack" value="10000"></constructor-arg>
//3、p形式（需要引入命名空間） <bean id="skill3" class="com.spring.beans.Skill" p:name="劍擊" p:attack="7000">
//4、特殊字符的處理（CDATA）<property name="sex" ><value><![CDATA[男]]></value></property>
//5、自動裝配 bean設置自動裝配autowire <bean id="person" class="com.spring.beans.Person" autowire="byType"/>
//6、作用於Scope 默認singleton <bean id="person" class="com.spring.beans.Person" scope="singleton">
//7、讀取外部文件（如讀取數據源）
// 引入 <context:property-placeholder location="classpath:database.properties"/>
// 然後使用${xxx}(類似EL) <property name="driverClass" value="${driverclass}"></property>
//8、SpringEL 使用#{} 可以運算/調用靜態方法 <property name="field1" value="#{'field1'}"></property>
//9、list、map、Properties的使用
/*<list>
<ref bean="skill"/>
<ref bean="skill2"/>
<ref bean="skill3"/>
<bean class="com.spring.beans.Skill">
<property name="name" value="天賦技能"></property>
<property name="attack" value="20000"></property>
</bean>
</list>
