UrlRewriteFilter錯誤

Question

我正在使用maven，並將urlrewrite.xml放在源文件夾src/main/resources /下。配置的web.xml是這樣的：

<filter> 
<filter-name>UrlRewriteFilter</filter-name> 
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class> 
<init-param> 
    <param-name>confPath</param-name> 
    <param-value>classpath:urlrewrite.xml</param-value>    
</init-param> 


</filter> 

    <filter-mapping> 
    <filter-name>UrlRewriteFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
    <dispatcher>REQUEST</dispatcher> 
    <dispatcher>FORWARD</dispatcher> 
    </filter-mapping> 

但得到的錯誤：org.tuckey.web.filters.urlrewrite.UrlRewriteFilter錯誤：無法找到classpath中urlrewrite的conf文件：urlrewrite.xml。如果我把它放在默認的loc中：/WEB-INF/urlrewrite.xml。有用。但我想符合maven規範並將所有配置放在資源文件夾下。

任何人都可以幫助我嗎？謝謝。

使用 'WEB-INF' This article這裏面

<init-param> 
    <param-name>confPath</param-name> 
    <param-value>/WEB-INF/urlrewrite.xml</param-value> 
</init-param> 

，並把urlrewrite.xml文件有安裝說明。

不是世界上最乾淨的解決方案，但我能找到解決辦法。請注意，我的應用程序是基於彈簧：

公共類EnhancedUrlRewriteFilter擴展UrlRewriteFilter {

private String confPath; 

private final Log logger = LogFactory.getLog (getClass()); 

@Override 
public void init(FilterConfig filterConfig) throws ServletException { 
    String confPathStr = filterConfig.getInitParameter("confPath"); 
    confPath = StringUtils.trim(confPathStr); 
    super.init (filterConfig); 
} 

@Override 
protected void loadUrlRewriter (FilterConfig aFilterConfig) throws ServletException { 

    try { 
     configure (aFilterConfig.getServletContext()); 
    } 
    catch (Throwable e) { 
     throw new IllegalArgumentException (e); 
    } 

} 

private void configure (ServletContext context) throws IOException { 

    ResourceLoader webApplicationContext = WebApplicationContextUtils.getWebApplicationContext (context); 

    Resource resource = webApplicationContext.getResource (confPath); 

    logger.debug ("Loaded urlrewrite.xml from " + resource.getFilename()); 

    InputStream inputStream = resource.getInputStream(); 

    URL confUrl = null; 

    try { 
     confUrl = context.getResource(confPath); 
    } catch (MalformedURLException e) { 
     logger.debug(e); 
    } 

    String confUrlStr = null; 
    if (confUrl != null) { 
     confUrlStr = confUrl.toString(); 
    } 

    if (inputStream != null) { 
     Conf conf = new Conf(context, inputStream, confPath, confUrlStr, false); 
     checkConf(conf); 
    } 
} 

}

，並在我的web.xml：

<filter> 
    <filter-name>UrlRewriteFilter</filter-name> 
    <filter-class>EnhancedUrlRewriteFilter</filter-class> 
    <init-param> 
     <param-name>confPath</param-name> 
     <param-value>classpath:urlrewrite.xml</param-value> 
    </init-param> 
    <init-param> 
     <param-name>logLevel</param-name> 
     <param-value>WARN</param-value> 
    </init-param> 
</filter>
