Spring-12 Factory Beans and Methods
static method in Class person
non-static method in personFactory
Spring-13 The P Namespace
注意Constructor 中的Arg 和建立的Bean之间的关系
p: tag 和 property tag 不要同时使用
Spring-14 Setting List Property
In beans.xml file
Insert constructor argument ----> (Right click constructor argument)Insert List Element ---->(Right click list element)Insert Value Element
<bean id="basket" class="com.caveofprogramming.spring.test.FruitBasket"> <constructor-arg value="patrick‘s basket"></constructor-arg> <constructor-arg> <list> <value>apple</value> <value>peach</value> <value>pear</value> <value>orange</value> <value>banana</value> </list> </constructor-arg> </bean>
Difference between ‘set‘ and ‘list‘
‘set‘ remove duplicate value.
Spring-15 Lists of Beans
beans.xml
<bean id="jungle" class="com.caveofprogramming.spring.test.Jungle"> <property name="largest" ref="elephant"></property> <property name="animals"> <list> <ref bean="lion" /> <ref bean="snake" /> <ref bean="elephant" /> </list> </property> </bean>
App.java
Jungle jungle =(Jungle)context.getBean("jungle"); System.out.println(jungle);
Result
Largest: Animal [name=Richard, type=elephant] Others: Animal [name=Igor, type=lion] Animal [name=Bob, type=snake] Animal [name=Richard, type=elephant]
Spring-16 Inner Beans
Wrong edition
<bean id="jungle" class="com.caveofprogramming.spring.test.Jungle"> <property name="largest"> <bean id="elephant" class="com.caveofprogramming.spring.test.Animal"> <property name="name" value="Richard"></property> <property name="type" value="elephant"></property> </bean> （inner bean） </property> <property name="animals"> <list> <ref bean="lion" /> <ref bean="snake" /> <ref bean="elephant" /> (This part need to be deleted) </list> </property> </bean>
Reason: If you got an bean defined as an inner bean, you cannot refer to it somewhere else
<bean id="jungle" class="com.caveofprogramming.spring.test.Jungle"> <property name="largest"> <bean id="elephant" class="com.caveofprogramming.spring.test.Animal"> <property name="name" value="Richard"></property> <property name="type" value="elephant"></property> </bean> </property> <property name="animals"> <list> <bean id="lion" class="com.caveofprogramming.spring.test.Animal"> <property name="name" value="Igor"></property> <property name="type" value="lion"></property> </bean> <bean id="snake" class="com.caveofprogramming.spring.test.Animal"> <property name="name" value="Bob"></property> <property name="type" value="snake"></property> </bean> </list> </property> </bean>
Spring-17 Property map
Insert property(foods)--->Insert props--->Insert prop element
<bean id="jungle" class="com.caveofprogramming.spring.test.Jungle"> <property name="foods"> <props> <prop key="monkey">banana</prop> <prop key="panda">bamboo</prop> <prop key="snake">eggs</prop> </props> </property> </bean>
Spring-18 Arbitrary Maps as Bean Properties
Insert property(animals)--->insert Map--->insert Entity(entity key : lion value-ref: lion)
<bean id="jungle" class="com.caveofprogramming.spring.test.Jungle"> <property name="foods"> <props> <prop key="monkey">banana</prop> <prop key="panda">bamboo</prop> <prop key="snake">eggs</prop> </props> </property> <property name="animals"> <map> <entry key="lion" value-ref="lion"></entry> <entry key="snake" value-ref="snake"></entry> <entry key="elephant" value-ref="elephant"></entry> </map> </property> </bean>
