依赖注入的几种方式
为数组类型属性赋值
直接配置property中的array属性
<bean id="studentFive" class="com.gu.spring.pojo.Student">
<property name="sid" value="1003"></property>
<property name="sname" value="lisi"></property>
<property name="age" value="23"></property>
<property name="gender" value="男"></property>
<property name="hobby">
<array>
<value>抽烟</value>
<value>喝酒</value>
<value>烫头</value>
</array>
</property>
</bean>
为集合属性赋值
为list属性赋值
<bean id="clazzOne" class="com.gu.spring.pojo.Clazz">
<property name="cid" value="1111"></property>
<property name="cname" value="最强王者班"></property>
<property name="students" ref="studentList"></property>
<property name="students">
<list>
<ref bean="studentOne"></ref>
<ref bean="studentTwo"></ref>
<ref bean="studentThree"></ref>
</list>
</property>
</bean>
若为Set集合类型属性赋值，只需要将其中的list标签改为set标签即可
为map属性赋值
<property name="teacherMap" ref="teacherMap"></property>
<property name="teacherMap">
<map>
<entry key="10086" value-ref="teacherOne"></entry>
<entry key="10087" value-ref="teacherTwo"></entry>
</map>
</property>
引用集合类型的bean
<!-- 配置一个集合类型的bean需要使用util的约束 -->
<util:list id="studentList">
<ref bean="studentOne"></ref>
<ref bean="studentTwo"></ref>
<ref bean="studentThree"></ref>
</util:list>
<bean id="teacherOne" class="com.gu.spring.pojo.Teacher">
<property name="tid" value="10086"></property>
<property name="tname" value="yiyi"></property>
</bean>
<bean id="teacherTwo" class="com.gu.spring.pojo.Teacher">
<property name="tid" value="10087"></property>
<property name="tname" value="erer"></property>
</bean>
<util:map id="teacherMap">
<entry key="10086" value-ref="teacherOne"></entry>
<entry key="10087" value-ref="teacherTwo"></entry>
</util:map>
<bean id="studentSix" class="com.gu.spring.pojo.Student"
p:sid="1005" p:sname="xiaoming" p:gender="女" p:teacherMap-ref="teacherMap"
></bean>
