修改Struts2的struts.xml配置文件位置

　　默認情況下Struts的配置文件名稱為strutsxml且該文件放在src根目錄下如下圖所示

　　如果需要修改strutsxml的位置例如把strutsxml放到struts文件夾下結構如下圖所示該怎麼辦呢?

　　Struts在webxml中的一般配置如下

　　[html]

　　struts

　　orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter

　　struts

　　/*

　　struts

　　orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter

　　struts

　　/*

　　為了弄清Stuts是如何加載配置文件的先查看Struts的StrutsPrepareAndExecuteFilter類

　　[java] package orgapachestrutsdispatcherngfilter;

　　/**

　　* Handles both the preparation and execution phases of the Struts dispatching process This filter is better to use

　　* when you dont have another filter that needs access to action context information such as Sitemesh

　　*/

　　public class StrutsPrepareAndExecuteFilter implements StrutsStatics Filter {

　　protected PrepareOperations prepare;

　　protected ExecuteOperations execute;

　　protected List excludedPatterns = null;

　　public void init(FilterConfig filterConfig) throws ServletException {

　　InitOperations init = new InitOperations();

　　try {

　　FilterHostConfig config = new FilterHostConfig(filterConfig);

　　initinitLogging(config);

　　Dispatcher dispatcher = initinitDispatcher(config);

　　initinitStaticContentLoader(config dispatcher);

　　prepare = new PrepareOperations(filterConfiggetServletContext() dispatcher);

　　execute = new ExecuteOperations(filterConfiggetServletContext() dispatcher);

　　thisexcludedPatterns = initbuildExcludedPatternsList(dispatcher);

　　postInit(dispatcher filterConfig);

　　} finally {

　　initcleanup();

　　}

　　}

　　/**

　　* Callback for post initialization

　　*/

　　protected void postInit(Dispatcher dispatcher FilterConfig filterConfig) {

　　}

　　public void doFilter(ServletRequest req ServletResponse res FilterChain chain) throws IOException ServletException {

　　HttpServletRequest request = (HttpServletRequest) req;

　　HttpServletResponse response = (HttpServletResponse) res;

　　try {

　　preparesetEncodingAndLocale(request response);

　　preparecreateActionContext(request response);

　　prepareassignDispatcherToThread();

　　if ( excludedPatterns != null && prepareisUrlExcluded(request excludedPatterns)) {

　　chaindoFilter(request response);

　　} else {

　　request = preparewrapRequest(request);

　　ActionMapping mapping = preparefindActionMapping(request response true);

　　if (mapping == null) {

　　boolean handled = executeexecuteStaticResourceRequest(request response);

　　if (!handled) {

　　chaindoFilter(request response);

　　}

　　} else {

　　executeexecuteAction(request response mapping);

　　}

　　}

　　} finally {

　　preparecleanupRequest(request);

　　}

　　}

　　public void destroy() {

　　preparecleanupDispatcher();

　　}

　　}

　　package orgapachestrutsdispatcherngfilter;

　　/**

　　* Handles both the preparation and execution phases of the Struts dispatching process This filter is better to use

　　* when you dont have another filter that needs access to action context information such as Sitemesh

　　*/

　　public class StrutsPrepareAndExecuteFilter implements StrutsStatics Filter {

　　protected PrepareOperations prepare;

　　protected ExecuteOperations execute;

　　protected List excludedPatterns = null;

　　public void init(FilterConfig filterConfig) throws ServletException {

　　InitOperations init = new InitOperations();

　　try {

　　FilterHostConfig config = new FilterHostConfig(filterConfig);

　　initinitLogging(config);

　　Dispatcher dispatcher = initinitDispatcher(config);

　　initinitStaticContentLoader(config dispatcher);

　　prepare = new PrepareOperations(filterConfiggetServletContext() dispatcher);

　　execute = new ExecuteOperations(filterConfiggetServletContext() dispatcher);

　　thisexcludedPatterns = initbuildExcludedPatternsList(dispatcher);

　　postInit(dispatcher filterConfig);

　　} finally {

　　initcleanup();

　　}

　　}

　　/**

　　* Callback for post initialization

　　*/

　　protected void postInit(Dispatcher dispatcher FilterConfig filterConfig) {

　　}

　　public void doFilter(ServletRequest req ServletResponse res FilterChain chain) throws IOException ServletException {

　　HttpServletRequest request = (HttpServletRequest) req;

　　HttpServletResponse response = (HttpServletResponse) res;

　　try {

　　preparesetEncodingAndLocale(request response);

　　preparecreateActionContext(request response);

　　prepareassignDispatcherToThread();

　　if ( excludedPatterns != null && prepareisUrlExcluded(request excludedPatterns)) {

　　chaindoFilter(request response);

　　} else {

　　request = preparewrapRequest(request);

　　ActionMapping mapping = preparefindActionMapping(request response true);

　　if (mapping == null) {

　　boolean handled = executeexecuteStaticResourceRequest(request response);

　　if (!handled) {

　　chaindoFilter(request response);

　　}

　　} else {

　　executeexecuteAction(request response mapping);

　　}

　　}

　　} finally {

　　preparecleanupRequest(request);

　　}

　　}

　　public void destroy() {

　　preparecleanupDispatcher();

　　}

　　}可以看到有個public void init(FilterConfig filterConfig) throws ServletException { } 方法很明顯這個方法在啟動時會被調用然後加載classes目錄下的strutsxml配置文件配置文件參數名稱為filterConfig因此我們可以指定Struts Filter 的參數這和指定Servlet參數相同配置即可配置如下

　　[html]

　　struts

　　orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter

　　filterConfig

　　classpath:struts/strutsxml

　　struts

　　/*

　　struts

　　orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter

　　filterConfig

　　classpath:struts/strutsxml

　　struts

　　/*

　　這樣配置後就可以正常加載指定的Struts配置文件了
