In this sample I'm integrating the spring & velocity with struts2 and portlets, but could be extrapolated to any other environment.
The recipe consists of:
- applicationContextBeans.xml -> the sprig config file (the glue)
- registrarse.vm -> a velocity template of our e-mail
- EmailService.java & EmailServiceImpl.java -> the classes to apply the data to the template and send the e-mail. These classes will be the same for all the e-mails, so could be in a separate jar.
- RegistrarseAction.java -> the struts2 action
-applicationContextBeans.xml:
<bean id="emaiInformacionlService" class="es.project.miGestion.administracionDatos.service.EmailServiceImpl" scope="prototype">
<property name="velocityEngine" ref="velocityEngine"></property>
