spring創建對象的多種xml配置

普通 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"

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
 
     <!-- IOC容器的配置，要創建的所有的對象都配置在這裏 -->
     <!-- 構造方法 -->
    <bean id="admin1" class="a_erchou.Admin" scope="singleton">
       <constructor-arg value="1"></constructor-arg>
       <constructor-arg value="1"></constructor-arg>
       <constructor-arg value="1"></constructor-arg>
    </bean>
    <!-- set方法 -->
    <bean id = "admin2" class="a_erchou.Admin" scope="singleton">
       <property name="id" value="2"></property>
       <property name="userName" value="2"></property>
       <property name="password" value="2"></property>
    </bean>
</beans>

內部bean配置 ：

     <bean id = "adminAction" class="DI.AdminAction" scope="prototype">
        <property name="service" ref="adminService"></property>
     </bean> -->
     <!-- 內部bean 只能自己使用-->
     <!-- <bean id = "adminAction" class="DI.AdminAction" scope="prototype">

     <bean id = "adminAction" class="DI.AdminAction" scope="prototype" p:service-ref="adminService"></bean>
     
</beans>

工廠配置：

     <!-- IOC容器的配置，要創建的所有的對象都配置在這裏 -->
     
     <!-- 默認無參數 -->
     <bean id = "admin1" class="erchou.Admin" scope="singleton"></bean>
     
     <!-- 帶參數構造器 -->
     <bean id = "admin2" class="erchou.Admin" scope="singleton">

     </bean>
     <!-- 工廠創建對象方法 -->
     <!-- 調用實例方法   :1.先創建工廠 2.創建對象-->
     <bean id = "factroy" class="erchou.ObjectFactoty"></bean>
     <bean id = "admin3" factory-bean="factroy" factory-method="getAdmin"></bean>
     
     
     <!-- 靜態方法 -->
     <bean id = "admin4" class="erchou.ObjectFactoty" factory-method="getStaticAdmin"></bean>
