            <!-- 使用類構造器實例化 -->
            <bean id="personService1" class="service.PersonServiceImpl"></bean>
            <!-- 使用靜態工廠方法實例化 -->
            <bean id="personService2" class="service.PersonServiceFactory" factory-method="createPersonService"></bean>
            <!-- 使用實例工廠方法實例化 -->
            <bean id="personServiceFactory" class="service.PersonServiceFactory"></bean>

依賴注入兩種方法：

<bean id="personDao" class="dao.PersonDaoImpl"></bean> 
<bean id="personService1" class="service.PersonServiceImpl">
    <!-- ref注入-->
    <property name="personDao" ref="personDao"></property>
</bean>

<bean id="personService4" class="service.PersonServiceImpl">
                <!-- 內部bean注入 -->
                <property name="personDao">
                    <bean class="dao.PersonDaoImpl"/>
                </property>
            </bean>

其中還可以爲Service的基本屬性注入值，比如service有屬性：private String name;

<bean id="personService4" class="service.PersonServiceImpl">
                <!-- 內部bean注入 -->
    <property name="name" value=“hello”>
     </property>
 </bean>

集合屬性的注入

<bean id="personService4" class="service.PersonServiceImpl">
<property name="list">
<list>
<value>1</value>
<value>2</value>
</list>
</property>
</bean>
