Modify the Struts.xml profile location for Struts2

By default, the profile name of Struts2 is called Struts.xml, and the file is placed under the SRC root directory. As shown in the following:

If you need to modify the location of the struts.xml, for example, put Struts.xml in the Struts2 folder, as shown in the structure, what should I do?

The general configuration of Struts2 in Web. XML is as follows:

    <!--configuration Struts2 filter: Strutsprepareandexecutefilter--    <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>

To find out how STUTS2 loads the configuration file, first look at the Struts2 Strutsprepareandexecutefilter class:

Package org.apache.struts2.dispatcher.ng.filter;/** * Handles Both the preparation and execution phases of the Struts disp  Atching process.  This filter was better to the use * if you don't have another filter, the needs access to action context information, such as Sitemesh.    */public class Strutsprepareandexecutefilter implements Strutsstatics, Filter {protected prepareoperations prepare;    Protected Executeoperations execute;protected list<pattern> excludedpatterns = null;        public void init (Filterconfig filterconfig) throws Servletexception {initoperations init = new Initoperations ();            try {filterhostconfig config = new Filterhostconfig (filterconfig);            init.initlogging (config);            Dispatcher Dispatcher = init.initdispatcher (config);            Init.initstaticcontentloader (config, dispatcher);            Prepare = new Prepareoperations (Filterconfig.getservletcontext (), dispatcher); Execute = new Executeoperations (FiltercoNfig.getservletcontext (), dispatcher); this.excludedpatterns = init.buildexcludedpatternslist (dispatcher);        Postinit (Dispatcher, filterconfig);        } finally {Init.cleanup ();  }}/** * Callback for post initialization */protected void Postinit (Dispatcher Dispatcher, Filterconfig Filterconfig) {} public void DoFilter (ServletRequest req, servletresponse Res, Filterchain chain) throws Ioexcepti        On, servletexception {httpservletrequest request = (httpservletrequest) req;        HttpServletResponse response = (httpservletresponse) res;            try {Prepare.setencodingandlocale (request, response);            Prepare.createactioncontext (request, response); Prepare.assigndispatchertothread (); if (excludedpatterns! = null && prepare.isurlexcluded (Request, Excludedpatterns) {Chain.dofilter (request, response);} else {request = Prepare.wraprequest (request); actionmapping mapping = prepare.findactionmapping(Request, response, true); if (mapping = = NULL) {Boolean handled = Execute.executestaticresourcerequest (Request, response if (!handled) {chain.dofilter (request, Response);}}        else {execute.executeaction (request, response, mapping);}}        } finally {prepare.cleanuprequest (request);    }} public void Destroy () {prepare.cleanupdispatcher (); }}

As you can see, there is a public void init (Filterconfig filterconfig) throws Servletexception {...} method, and it is clear that this method will be called at startup, and then Load the Struts.xml configuration file under the classes directory . The configuration file parameter name is Filterconfig. Therefore, we can specify the parameters of the Struts2 Filter, which is the same as specifying the servlet parameter, and is configured <init-param>. The configuration is as follows:

    <filter>        <filter-name>struts2</filter-name>        <filter-class> Org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class>        <init-param >            <param-name>filterConfig</param-name>            <param-value>classpath:struts2/struts.xml </param-value>        </init-param>    </filter>    <filter-mapping>        < filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </ Filter-mapping>

With this configuration, the specified struts profile can be loaded normally.
