1 Importing JAR Packages

• This article will give the address of the project at the end, you do not need to look urgently.

2 Configuring the Web. xml file

<?XML version= "1.0" encoding= "UTF-8"?><Web-appxmlns= "Http://xmlns.jcp.org/xml/ns/javaee"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"version= "3.1">    <!--Spring's listener -    <Listener>        <Listener-class>Org.springframework.web.context.ContextLoaderListener</Listener-class>    </Listener>    <Context-param>        <Param-name>Contextconfiglocation</Param-name>        <Param-value>Classpath*:applicationcontext.xml</Param-value>    </Context-param>    <Filter>        <Filter-name>Opensessioninviewfilter</Filter-name>        <Filter-class>Org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</Filter-class>    </Filter>    <filter-mapping>        <Filter-name>Opensessioninviewfilter</Filter-name>        <Url-pattern>/*</Url-pattern>    </filter-mapping>    <!--Struts2 's core filter -    <Filter>        <Filter-name>Struts2</Filter-name>        <Filter-class>Org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</Filter-class>    </Filter>    <filter-mapping>        <Filter-name>Struts2</Filter-name>        <Url-pattern>/*</Url-pattern>    </filter-mapping>            </Web-app>

• Among them, Struts2 's core filter does not have to say much.
• Spring's listener is the ServletContext listener, and when the project starts, Contextloaderlistener puts applicationcontext.xml into the domain properties of the ServletContext object.
• Because of the ServletContext object, the <context-param> node needs to be configured in Web. Xml.

3 Action.java

• Example: Classesaction.java
