解決了,給大家 看一下,多多指教
1.重寫FilterDispatcher 類的三個方法,我的struts-*.xml的路徑在WEB-INF/modules/struts文件夾下,JLTEnvironment類爲我的應用的配置路徑
public class JLTFilterDispatcher extends FilterDispatcher {
@Override
protected Dispatcher createDispatcher(FilterConfig filterConfig) {
Map <String, String> params = new HashMap <String, String>();
for (Enumeration e = filterConfig.getInitParameterNames(); e
.hasMoreElements();) {
String name = (String) e.nextElement();
String value = filterConfig.getInitParameter(name);
params.put(name, value);
}
// 加載modules下的struts配置文件
getStrutsConfig(params);
return new Dispatcher(filterConfig.getServletContext(), params);
}
* 加載modules下的struts配置文件
private void getStrutsConfig(Map <String, String> m) {
String strutsPath = new String(
"struts-default.xml,struts-plugin.xml,struts.xml");
File f = new File(JLTEnvironment.getModulesHome()+"/struts");
if (f.getName().equals("struts")) {
File[] ff = f.listFiles();
if (ff != null && ff.length > 0) {
for (int i = 0; i < ff.length; i++) {
String fname = ff[i].getName();
if (fname.startsWith("struts-") && fname.endsWith(".xml")) {
strutsPath+=","+ff[i].getAbsolutePath();
}
}
}
}
m.put("config", strutsPath);
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
//獲得應用的路徑
ServletContext ctx = filterConfig.getServletContext();
String home = ctx.getRealPath("/");
home = home.replace('//', '/');
if (!home.endsWith("/")) {
home = home + "/";
}//初始化應用環境參數
JLTEnvironment.init(home, ctx);
super.init(filterConfig);
}
}
2.web.xml更改爲
<filter>
<filter-name>struts2 </filter-name>
<filter-class>
com.jlt.core.JLTFilterDispatcher
</filter-class>
</filter>
3.這樣,WEB-INF/modules/struts下的所有以struts-開關的以xml結尾的xml文件都會被自動加載進去,不用去改其它配置了,呵呵
WEB-INF/struts/struts-sample.xml
配置如下
<filter>
<filter-name>struts2 </filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher </filter-class>
<init-param>
<param-name>config </param-name>
<param-value>
struts-default.xml
,struts-plugin.xml
,../struts/struts.xml
,../struts/struts-sample.xml
</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2 </filter-name>
<url-pattern>/* </url-pattern>
</filter-mapping>
