Class ConstrettoSingletonFactoryBean

java.lang.Object
  org.constretto.spring.ConstrettoSingletonFactoryBean

All Implemented Interfaces:

FactoryBean

public class ConstrettoSingletonFactoryBean
extends Object
implements FactoryBean

A factory bean used to instantiate spring beans depending on the environment you are running in. This factory bean use the AssemblyContextResolver to lookup the running environment. the value of this property is used to lookup in the map of beans.

Usage :

 <bean id="productionBean" class="com..ProductionTestBean">
      <property name="value" value="production value" />
  </bean>
 

  <bean id="developmentBean" class="com..DevelopmentTestBean">
      <property name="value" value="development value" />
  </bean>
 

  <bean id="myBean" class="org.constretto.spring.ConstrettoSingletonFactoryBean">
      <constructor-arg>
          <map>
              <entry key="production" value-ref="productionBean" />
              <entry key="development" value-ref="developmentBean" />
          </map>
      </constructor-arg>
  </bean>
 

  <bean id="myBeanOverriddenDefaultPrefix" class="org.constretto.spring.propertyplaceholder.factory.ConstrettoSingletonFactoryBean">
    <constructor-arg>
          <map>
              <entry key="production" value-ref="productionBean" />
              <entry key="development" value-ref="developmentBean" />
          </map>
      </constructor-arg>
      <constructor-arg ref="developmentBean" />
  </bean>
