Using STRUTS2 in Intellij idea

It is said that there are a lot of loopholes in the struts2, but as a study I also use it, because the book is based on this said Ah.

No wonder the official website also has no struts2.2.1 version of the download.

1. Download struts2.2.1 GA version

2. Create a new Web project

3. Import the following packages into the Web/web-inf/lib directory and add the packages

4. Add the following configuration to the Web. xml file

<?xml version= "1.0" encoding= "UTF-8"?>
<web-app xmlns= "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" >

    <!--define the core of STRUTS2 filter--
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <!--let Struts2 's core filter intercept all requests--
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>


</web-app>
