+== 資料集合 == 
+
+對於像 '''陣列、java.util.List、java.util.Set、java.util.Map''' 等'''集合物件'''，在注入前必須填充入一些物件至集合中，然後再將集合物件注入至所需的Bean中，
+
+ * SomeBean ：
+
+{{{
+#!java
+public class SomeBean {
+    private String[] someStrArray;
+    private SomeObj[] someObjArray;
+    private List someList;
+    private Map someMap;
+    ....
+
+}
+}}}
+
+ * B.xml ：陣列,List => <list>  ; Map => <map>
+
+{{{
+#!xml
+<beans>
+    <bean id="someBean" class="onlyfun.caterpillar.SomeBean">
+        <property name="someArray">
+            <list>
+                <value>Hello!Justin!</value>
+                <value>Hello!Momor!</value>
+                <value>Hello!Bush!</value>
+            </list>
+        </property>
+        <property name="someObjArray">
+            <list>
+                <ref bean="someObj1"/>
+                <ref bean="someObj2"/>
+            </list>
+        </property>
+        <property name="someList">
+            <list>
+                 <value>Hello!Justin!</value>
+                 <ref bean="someObj1"/>
+                 <ref bean="someObj2"/>
+            </list>
+        </property>
+        <property name="someMap">
+            <map>
+                 <entry key="somekey1">
+                     <ref bean="someObj1"/>
+                 </entry>
+                 <entry key="somekey2">
+                     <value>Hello!Justin!</value>
+                 </entry>
+            </map>
+        </property>
+    </bean>
+</beans>
+}}}
+
+上面的Bean定義檔是個綜合示範，陣列與List物件都是用<list>標籤來設定，而Map物件使用<map>標籤設定，並需要一個key值設定。
+
+ * Set => <set> ：
+
+{{{
+#!xml
+<set>
+    <value>a set element</value>
+    <ref bean="otherBean"/>
+    <ref bean="anotherBean"/>
+</set>
+}}}
