org.settings4j.helper.spring

Class Settings4jFactoryBean

java.lang.Object

org.settings4j.helper.spring.Settings4jFactoryBean

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean

public class Settings4jFactoryBean
extends Object
implements org.springframework.beans.factory.FactoryBean<Object>, org.springframework.beans.factory.InitializingBean

BeanFactory which gets the Object from Settings4j.getObject(String).
This can also be used for DataSource-Objects with the JNDI-Name as Key.

Simple SpringBean Example:

The following Example can be configured with the settings4j-Key "env/MyVariable".
e.g.: System.setProperty("env/MyVariable", "Hallo World");
OR with JNDI-Context OR in a Classpath-File under "classpath:env/MyVariable" Or with a custom Connector-Implementation.

  <bean id="MyConfigurableValue" class="org.settings4j.helper.spring.Settings4jFactoryBean">
      <property name="key"><value>env/MyVariable</value></property>
  </bean>
 

More complex SpringBean Example:

This Example shows how a Hibernate SessionFactory can optional customized with additional HibernateProperties.

  <bean id="hibernateProperties"
      class="org.springframework.beans.factory.config.PropertiesFactoryBean">
      <property name="locations">
          <list>
              <value>classpath:org/settings4j/helper/spring/DefaultHibernate.properties</value>
              <bean class="org.settings4j.helper.spring.Settings4jFactoryBean">
                  <property name="key">
                      <value>env/MyCustomProprtiesLocationKey</value>
                  </property>
                  <property name="defaultObject">
                      <!-- This could also be an empty Property-File But it must Exist. -->
                      <!-- PropertiesFactoryBean cannot handle invalid Paths. -->
                      <value>classpath:org/settings4j/helper/spring/DefaultHibernate.properties</value>
                  </property>
              </bean>
          </list>
      </property>
  </bean>

  <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
      <property name="dataSource" ref="db2Datasource2" />
      <property name="hibernateProperties" ref="hibernateProperties" />
      ....
  </bean>
