Class WebPBEInitializationContextListener

Object
  org.jasypt.web.pbeconfig.WebPBEInitializationContextListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public final class WebPBEInitializationContextListener
extends Object
implements javax.servlet.ServletContextListener

ContextListener which takes a WebPBEInitializer implementation class name as a parameter (<context-param>) and calls its initializeWebPBEConfigs() method to allow the webapp to create its PBE encryptors and declare their associated WebPBEConfig objects.

An example web.xml fragment:

    <context-param>
      <param-name>webPBEInitializerClassName</param-name>
      <param-value>myapp.MyWebPBEInitializer</param-value>
    </context-param>

    <listener>
      <listener-class>
        org.jasypt.web.pbeconfig.WebPBEInitializationContextListener
      </listener-class>
    </listener>
 

Important: If the web application uses Spring Framework, WebPBEConfig objects are declared as beans in the Spring context and this Spring context is initialized at application deploy time (with Spring's ContextLoaderListener), the use of this context listener will become unnecessary.
