spring - ioc - 配置文件注入属性

application.xml

    <!--ioc注入属性的两种方式：构造器注入与set方法注入 | 注入基本数据类型与引用数据类型-->
    <!--1.无参构造器创建对象-->
    <bean id="human" class="com.levi.dao.Human"/>
    <!--2.有参构造器创建对象-->
    <bean id="user" class="com.levi.dao.User">
        <!--构造器注入:基本数据类型与引用数据类型-->
        <constructor-arg name="name" value="levi"/>
        <constructor-arg name="id" value="12"/>
        <constructor-arg name="human" ref="human"/>
        <!--set方法注入：基本数据类型与引用数据类型-->
        <property name="id" value="12"/>
        <property name="name" value="levi"/>
        <property name="human" ref="human"/>
    </bean>

    <!--3.注入集合-->
    <bean id="human_test" class="com.levi.dao.Human">
        <!--3.1 list集合-->
        <property name="list">
            <list>
                <value>1</value>
                <ref bean="human"/>
            </list>
        </property>
        <!--3.2 map集合-->
        <property name="map">
            <map>
                <entry key="1" value="1"/>
                <entry key-ref="human" value-ref="human"/>
            </map>
        </property>
        <!--3.3 set集合-->
        <property name="set">
            <set>
                <value>1</value>
                <ref bean="human"/>
            </set>
        </property>
        <!--3.4 数组-->
        <property name="array">
            <array>
                <value>1</value>
                <ref bean="human"/>
            </array>
        </property>
    </bean>
