org.settings4j.helper.spring

Class Settings4jContextLoaderListener

java.lang.Object

org.springframework.web.context.ContextLoader

org.springframework.web.context.ContextLoaderListener

org.settings4j.helper.spring.Settings4jContextLoaderListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public class Settings4jContextLoaderListener
extends org.springframework.web.context.ContextLoaderListener

ServletContextListener to initialize the Settings4jContextLoader.

This Implementation replaces the ContextLoaderListener

Usage - Make SpringContext configurable

Example Configuration could look like the following:

 web.xml
 --------------------------------------
 <context-param>
     <param-name>settings4jContextConfigLocation</param-name>
     <param-value>
         ${com/myCompany/myApp/appContextSecurity},
         /WEB-INF/applicationContext-otherBeans.xml
     </param-value>
 </context-param>
 
 <listener>
     <display-name></display-name>
     <listener-class>org.settings4j.helper.spring.Settings4jContextLoaderListener</listener-class>
 </listener>
 --------------------------------------
 

With this configuration you define with tehKey teh path to your Security configuration.

Server config Example

Example Configuration in TOMCAT:
Start tomcat with -Dcom/myCompany/myApp/appContextSecurity=file:.../applicationContext-security-alwaysAdmin.xml
Or configured a JNDI Value:

 TOMCAT context.xml
 --------------------------------------
 <Environment name ="com/myCompany/myApp/appContextSecurity" 
              value="/WEB-INF/applicationContext-security.xml" 
              type="java.lang.String" />
 
 --------------------------------------
 

Default Values

It is recommended to use this in combination with DefaultPropertiesLoader:

 web.xml
 --------------------------------------
 <context-param>
     <param-name>settings4jDefaultProperties</param-name>
     <param-value>
         com/myCompany/myApp/appContextSecurity=/WEB-INF/applicationContext-security.xml
     </param-value>
 </context-param>
 
 <context-param>
     <param-name>settings4jContextConfigLocation</param-name>
     <param-value>
         ${com/myCompany/myApp/appContextSecurity},
         /WEB-INF/applicationContext-otherBeans.xml
     </param-value>
 </context-param>
 
 <listener>
     <display-name></display-name>
     <listener-class>org.settings4j.helper.spring.Settings4jContextLoaderListener</listener-class>
 </listener>
 --------------------------------------
