spring property initialization with java property

[Kazimierz Trzonek]

Hi, I would like to initialize my byte property with java constant, is it
possible? how can I do it? where is it explained? i checked spring reference, and there's no such example (http://static.springframework.org/spring/docs/2.5.x/reference/beans.html).
I would like sth like:
<property name="whenExhaustedAction" >
<value>
org.apache.commons.pool.impl.GenericObjectPool.WHEN_EXHAUSTED_FAIL
</value>
</property>

You could use a FieldRetrievingFactoryBean to retrieve the static WHEN_EXHAUSTED_FAIL.

 <bean id="org.apache.commons.pool.impl.GenericObjectPool.WHEN_EXHAUSTED_FAIL" class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean" />
 
 <bean id="myBean" class="com.springDemo.custprops.ConnectionType">
   <property name="whenExhaustedAction">
   <ref bean="org.apache.commons.pool.impl.GenericObjectPool.WHEN_EXHAUSTED_FAIL"/>
   </property>
 </bean>

Actually it is much easier than that.

The util namespace can access a constant for you. I believe it is

<util:constant> and tell it which constant to use.

Here is the documentation link

http://static.springframework.org/spring/docs/2.5.x/reference/xsd-config.html#xsd-config-body-schemas-util-constant

You will notice the first example is the same that Christophe posted, then the next code example is with using <util:constant> to make it easier.

Thank You, both solutions work.

Thanks Mark, I didn't know about util:constant.
