是否有任何办法使过滤器不包含分方向?
例如。
我有根基中的C.xhtml档案,我还有一小数点,称为“测试”,其卷宗范围相同。 是否有人可以把过滤器绘制成背景材料,而不是“测试”目录中的文档?

<代码>ur-pattern在配对方面确实有限制性。 它只允许准确、事先确定或准确匹配。 不进行中校/校对配对。 e.g./*xhtml
您打算做的工作。
如果您希望在<代码>/测试代码>中排除XVD 仅以倍数计算,您的最好方式是Filter
倾听url-pattern
>> ∗.xhtml,该编码基本上在doFilter(
方法>上做了以下工作:
// First cast ServletRequest to HttpServletRequest.
HttpServletRequest hsr = (HttpServletRequest) request;
// Check if requested resource is not in /test folder.
if (!hsr.getServletPath().startsWith("/test/")) {
// Not in /test folder. Do your thing here.
}
如有必要,请将“<代码>/test”作为“<init-param>”;
的过滤器,以便你能够控制“密码”内而不是“过滤器代码”内的价值。
解决办法是,你基本上需要自己的“过滤器”类别,并将“URLs”界定为“过滤器的内分数”。
package test;

import javax.servlet.FilterChain;

public class LoginValidationFilter implements Filter {
private String loginPage = "";

public void init(FilterConfig filterConfig) throws ServletException {
this.loginPage = filterConfig.getInitParameter("loginPage");
String[] excluded = filterConfig.getInitParameter("excludedURLs").split(";");
excludedURLs = new ArrayList<String>();
for (int i = 0; i < excluded.length; i++) {
excludedURLs.add(excluded[i]);
}
}
public void destroy() {
this.loginPage = "";
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException,
ServletException {
HttpServletRequest httpRequest = request instanceof HttpServletRequest ? (HttpServletRequest) request : null;
HttpServletResponse httpResponse = response instanceof HttpServletResponse ? (HttpServletResponse) response
: null;
if (httpRequest == null || httpResponse == null) {
filterChain.doFilter(request, response);
return;
}
boolean isExcludedURL = false;
for (int i = 0; i < excludedURLs.size(); i++) {
if (httpRequest.getRequestURL().indexOf(excludedURLs.get(i)) > -1) {
isExcludedURL = true;
break;
}
}
if (isExcludedURL) {
filterChain.doFilter(request, response);
} else {
if (UserUtil.validateUserLogin(httpRequest)) {
filterChain.doFilter(request, response);
} else {
httpResponse.sendRedirect(httpRequest.getContextPath() + loginPage);
}
}
}
}
并界定过滤器、绘图和在网上排除URLs。
<filter>
<filter-name>LoginValidationFilter</filter-name>
<filter-class>test.LoginValidationFilter</filter-class>
<init-param>
<param-name>loginPage</param-name>
<param-value>/login.jsp</param-value>
</init-param>
<init-param>
<param-name>excludedURLs</param-name>
<param-value>/admin/;/assets/;/content/;/css/;/js/;/login.jsp;/login.cmd;/logout.cmd;forgot_password.jsp;pageName=</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>LoginValidationFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
利用标准服务器/过滤器的现有材料,没有直接办法排除该次子,因为<代码>*.ext风格测绘包括次子。 您可以通过宣布另一个专门处理<代码>/测试/*.xhtml的过滤器来开展这项工作,并相应地进行这项工作。
您能够增加你在环境中根基的每个档案的彩色价值,因此,过滤器将适用于这些档案,但不适用于测试夹中的档案(实际上它只适用于这些具体档案)。 以下是我的工作。
<url-pattern>/index.faces</url-pattern>
一些集装箱(如树脂)界定了在网络xml中过滤制图定义的延伸范围,该定义允许具体说明<代码>url-regexp,允许根据常规表述对l进行匹配。 (。) 参见贵集装箱是否有类似之处。
