Spel

  <bean id="server" class="java.net.InetAddress" factory-method="getLocalHost"/>

    @Value("#{server.hostName}")

<bean id="persistentMessageStore"
class="org.springframework.integration.jdbc.JdbcMessageStore">
<property name="tablePrefix" value="channel_" />
<property name="region" value="#{server.name}" />
<constructor-arg ref="masterDataSource" />
</bean>

PropertyEditor

<bean id="dateEditor"  class="org.springframework.beans.propertyeditors.CustomDateEditor">

    <constructor-arg>

      <bean class="java.text.SimpleDateFormat">

        <constructor-arg value="yyyy-MM-dd HH:mm:ss" />

      </bean>

    </constructor-arg>

    <constructor-arg value="true" />
