默认情况下Struts的配置文件名称为strutsxml且该文件放在src根目录下如下图所示
如果需要修改strutsxml的位置例如把strutsxml放到struts文件夹下结构如下图所示该怎么办呢?
Struts在webxml中的一般配置如下
[html]
struts
orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter
struts
/*
struts
orgapachestrutsdispatcherngfilterStrutsPrepareAndExecuteFilter
struts
/*
为了弄清Stuts是如何加载配置文件的先查看Struts的StrutsPrepareAndExecuteFilter类
[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;
/**

* 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();
}
}可以看到有个public void init(FilterConfig filterConfig) throws ServletException { } 方法很明显这个方法在启动时会被调用然后加载classes目录下的strutsxml配置文件配置文件参数名称为filterConfig因此我们可以指定Struts Filter 的参数这和指定Servlet参数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
/*
这样配置后就可以正常加载指定的Struts配置文件了
