Info

Spring is a lightweight container, providing centralized, automated configuration and wiring of your application objects, using a technique called "Dependency Injection"

...

  • Configure the Spring listener
Code Block
xml
xml
titleweb.xmlxml
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
  • Register your objects via the Spring configuration
Code Block

titleapplicationContext.xmlxml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="autodetect">
    <bean id="personManager" class="com.acme.PersonManager" scope="prototype"/>
    ...
</beans>

...

Your struts.xml file would then have the Action class attributes changed.

Code Block

titlestruts.xmlxml
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <include file="struts-default.xml"/>

    <package name="default" extends="struts-default">
        <action name="foo" class="com.acme.Foo">
            <result>foo.ftl</result>
        </action>
    </package>

    <package name="secure" namespace="/secure" extends="default">
        <action name="bar" class="bar">
            <result>bar.ftl</result>
        </action>
    </package>
</struts>

...

A typical spring configuration for bar could look as following.

Code Block
xml
xml
titleapplicationConext.xmlxml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans default-autowire="autodetect">
    <bean id="bar" class="com.my.BarClass" singleton="false"/>
    ...
</beans>

Comma separated list of regular expressions of classes that will be loaded by the reloading class loader(we suggest to add regular expressions so only action classes are handled by the reloading class loader)
