Question

对不起，如果这是微不足道的，但我对此很陌生。

这是我的pom依赖项：

这一切都是这样的，但如果我取消注释web.xml中的<filter>部分，我就得到了

一个或多个过滤器无法启动。

错误。我试过谷歌搜索，但没有成功。我正在使用Tomcat 8.我不知道还有什么可以说的问题，因为我试图弄明白自己。我正在关注this链接的教程（使用XML配置）。我尝试了不同的弹簧和弹簧安全版本，但每次战争爆炸时都会爆炸。它给出了上面的错误（当然，应用程序是无法访问的）

我更新了一些我不知道的事情......或者我错过了别的什么？我将在底部发布完整的错误堆栈。

Answer 1

所以，显然，问题在于spring-security.xml无法调用，所以我只是将spring-servlet.xml的内容移到了spring-security.xml，这一切现在都按预期工作了。

我希望将contextConfigLocation放在web.xml的{{1}}中，但是我无法添加多个（spring-servlet.xml），但我希望将它们分开。看起来这样做不会很好。

非常感谢@wero的日志提示！

Answer 2

我的情况下根本没有日志。发生这种情况是因为我的Filter实现类/方法之一抛出了NullPointerException。

Answer 3

问题：您的应用程序无法读取“ context-param”中web.xml中提到的“ spring-security.xml”文件。

RCA：按照以下步骤查找为什么/哪个过滤器无法启动。（通用方法）步骤1：以“调试模式”启动应用程序，并立即从IDE（Eclipse / Intelija ...）附加远程调试。第2步：在web.xml文件中提到的Filter类中应用断点。就我而言，它是“ DelegatingFilterProxy”。步骤3：一旦应用程序达到断点，则启用“ Java Exception BreakPoint-> org.springframework.beans.factory.BeansException”。步骤4：现在，IDE将向您显示发生异常的确切位置。您可以进一步调试并轻松解决此问题。

解决方案：确保您的应用程序能够读取“ context-param”中提到的spring-security.xml文件，才能解决此问题。

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring/appContext.xml /WEB-INF/spring/spring-security.xml
    </param-value>
</context-param>

注意：从日志中我没有得到任何信息。

Answer 4

我有一个类似的问题。我发现我的一个过滤器在init方法中引发了一个异常，它被记录在/usr/local/tomcat/logs/localhost.2019-12-07.log中，而不是'通常'日志（/ usr / local / tomcat / logs / catalina.out或/usr/local/tomcat/logs/catalina.2019-12-07.log）

将过滤器添加到web.xml后，一个或多个过滤器无法启动
