Introduction
Jetty can be assembled and configured in code or with almost any IoC style framework including spring. The jetty-spring module is included in jetty@codehaus with some convenience classes and a handy Main method to run jetty from spring.
Dependencies
As distributed, the jetty-hightide bundle does not include the spring dependencies:
- spring-1.2.8.jar
- commons-logging-1.0.4.jar
These dependencies should be downloaded and installed in $JETTY_HOME/lib/spring
Configuration
The configuration of Jetty via spring is simply a matter of calling the API as spring beans. The following is the default jetty-spring.xml file:
<beans> <bean id="contexts" class="org.eclipse.jetty.server.handler.ContextHandlerCollection"/> <bean id="Server" class="org.mortbay.jetty.spring.Server" init-method="start" destroy-method="stop"> <property name="threadPool"> <bean id="ThreadPool" class="org.eclipse.jetty.util.thread.QueuedThreadPool"> <property name="minThreads" value="10"/> <property name="maxThreads" value="50"/> </bean> </property> <property name="connectors"> <list> <bean id="Connector" class="org.eclipse.jetty.server.nio.SelectChannelConnector"> <property name="port" value="8080"/> </bean> </list> </property> <property name="handler"> <bean id="handlers" class="org.eclipse.jetty.server.handler.HandlerCollection"> <property name="handlers"> <list> <ref bean="contexts"/> <bean id="defaultHandler" class="org.eclipse.jetty.server.handler.DefaultHandler"/> </list> </property> </bean> </property> <property name="beans"> <list> <bean id="ContextDeployer" class="org.mortbay.jetty.spring.ContextDeployer"> <property name="contexts" ref="contexts"/> <property name="contextsDir" value="contexts"/> <property name="scanInterval" value="5"/> </bean> <bean id="WebAppDeployer" class="org.eclipse.jetty.deploy.WebAppDeployer"> <property name="contexts" ref="contexts"/> <property name="webAppDir" value="webapps"/> <property name="extract" value="true"/> <property name="defaultsDescriptor" value="etc/webdefault.xml"/> </bean> <bean class="org.eclipse.jetty.security.HashLoginService"> <property name="name" value="Test Realm"/> <property name="config" value="etc/realm.properties"/> <property name="refreshInterval" value="0"/> </bean> </list> </property> </bean> </beans>
Running Jetty with Spring
There are many ways to launch spring, including the jetty start.jar mechanism. The following command line starts the jetty spring config file including with the jetty-hightide distribution from codehaus:
java -jar start.jar OPTIONS=Server,All,spring \ start.class=org.mortbay.jetty.spring.Main \ etc/jetty-spring.xml
This uses the jetty-spring Main class to load the spring configuration file and join the resulting server.
