I've used Jasypt but I haven't gone the next step of integrating it with
Hibernate. Regardless, I think this might do the trick...
At the same level as components, pages, css, etc, create a package called
startup or something like that. It needs to build into WEB-INF/classes/. Then
put a class in it like this...
package mywebapp.startup;
public class MyHibernateEncyptorInitializer implements ServletContextListener {
ServletContext servletContext;
public void contextInitialized(ServletContextEvent servletContextEvent)
{
StandardPBEStringEncryptor strongEncryptor = new
StandardPBEStringEncryptor();
...
HibernatePBEEncryptorRegistry registry =
HibernatePBEEncryptorRegistry.getInstance();
registry.registerPBEStringEncryptor("strongHibernateStringEncryptor",
strongEncryptor);
}
public void contextDestroyed(ServletContextEvent servletContextEvent) {
// Nothing to do here
}
}
...it should compile into the webapp's classesand in web.xml, you'll find you
have display-name, context-param, filter, and filter-mapping sections...
<listener>
<listener-class>mywebapp.startup.MyHibernateEncryptorInitializer</listener-class>
</listener>
The encryptor will then be registered into Hibernate when the ServletContext is
initialized, ie. when the web server starts up.
