3.4. Bootstrapping a Spring Context in a WAR
Overview
You can bootstrap a Spring context in a WAR using Spring's ContextLoaderListener class.
Bootstrapping a Spring context in a WAR
For example, the following
web.xml file shows how to boot up a Spring application context that is initialized by the XML file, /WEB-INF/applicationContext.xml (which is the location of the context file in the generated WAR package):
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Camel Routes</display-name>
<!-- location of spring xml files -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<!-- the listener that kick-starts Spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>Maven dependency
In order to access the
ContextLoaderListener class from the Spring framework, you must add the following dependency to your project's pom.xml file:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring-version}</version>
</dependency>
Where the
spring-version property specifies the version of the Spring framework you are using.
