在Spring中配置默认​​URI

Question

Reading the doc about configuring a defaultUri ( http://docs.spring.io/spring-ws/site/reference/html/client.html ) I have this :

<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory"/>

<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
    <constructor-arg ref="messageFactory"/>
    <property name="defaultUri" value="http://example.com/WebService"/>
</bean>

I want to amend the property defaultUri so that it is read from a property configured in a different bean.

I could use something like :

<bean id="myBean" class="org.myBean" "factory-method=getDefaultUri"/>

the bean class "myBean" is then defined like :

public class myBean {

public String getDefaultUri(){
 ///invoke other method which get the URI
return "myUri"
}

}

So basically I want to configure the defaultUri using a property.

Are there other implementations other than what I outlined ?

Take a look at BeanPostProcessor interface, I believe is what you are looking for ... I use to do some processing in a scenario like this...

public interface BeanPostProcessor

"Factory hook that allows for custom modification of new bean instances, eg checking for marker interfaces or wrapping them with proxies."
