Is there a shorthand for creating a String constant in Spring context XML file?

Question

I need to define a string value in Spring context XML file that is shared by multiple beans.

This is how I do it:

<bean id="aSharedProperty" class="java.lang.String">     <constructor-arg type="java.lang.String" value="All beans need me :)"/> </bean> 

Creating a java.lang.String bean by passing a constructor argument of java.lang.String seems kludgy.

Is there a shortcut?

I know this property can be passed using PropertyOverrideConfigurer, but I want to keep this property within the XML file.

You can use PropertyPlaceholderConfigurer and keep values in xml:

<context:property-placeholder properties-ref="myProperties"/>  <bean id="myProperties"      class="org.springframework.beans.factory.config.PropertiesFactoryBean">   <property name="properties">     <props>       <prop key="aSharedProperty">All beans need me :)</prop>     </props>   </property> </bean> 

Then you reference it with:

<bean id="myBean" class="my.package.MyClass">   <property name="someField" value="${aSharedProperty}"/> </bean>
