Java IntelliJ 13 Tomcat 错误配置类 org.springframework.web.util.Log4jConfigListener 的应用程序侦听器

IntelliJ 13 Tomcat Error configuring application listener of class org.springframework.web.util.Log4jConfigListener

提问by brad142

I'm attempting to run a Java/Spring/Hibernate/Ivy application using IntelliJ 13 and its built in Tomcat deployment plugin. I'm using Tomcat 8.0.9, but I've also attempted this using Tomcat 6.0.39. I'm creating an artifact when I attempt to spin up Tomcat; a exploded war to be more specific. I'm using Ivy to resolve my dependencies and this is because it's a legacy app that doesn't use Maven. Stupid, I know.

我正在尝试使用 IntelliJ 13 及其内置的 Tomcat 部署插件运行 Java/Spring/Hibernate/Ivy 应用程序。我使用的是 Tomcat 8.0.9，但我也尝试过使用 Tomcat 6.0.39。当我尝试启动 Tomcat 时，我正在创建一个工件；更具体地说，是一场爆发式的War。我正在使用 Ivy 来解决我的依赖项，这是因为它是一个不使用 Maven 的遗留应用程序。愚蠢，我知道。

When attempting to run this application from inside of IntelliJ using any version of Tomcat I recieve the following messages in my 'Server' log:

尝试使用任何版本的 Tomcat 从 IntelliJ 内部运行此应用程序时，我在“服务器”日志中收到以下消息：

This is where those listeners are declared in my web.xml

这是在我的 web.xml 中声明这些侦听器的地方

<!-- Spring log4j listener -->
  <listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener> 
  <!-- Spring bootstrap listener -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>  
  <!-- Spring cleanup listener -->
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>

All of those classes are available on my classpath, but the problem seems to be that they're not available on Tomcat's classpath.

所有这些类都在我的类路径上可用，但问题似乎是它们在 Tomcat 的类路径上不可用。

After attempting to add my Ivy cache to the catalina.properties file under the 'shared.loader' property, in an effort to make those jars available to Tomcat's classpath, I was unable to format the directory correctly. Supposedly that would make the necessary jars available to Tomcat, and of course Tomcat doesn't provide documentation on the necessary syntax for specifying a shared loader... Help...

在尝试将我的 Ivy 缓存添加到 'shared.loader' 属性下的 catalina.properties 文件后，为了使这些 jar 可用于 Tomcat 的类路径，我无法正确格式化目录。据说这将使 Tomcat 可以使用必要的 jar，当然 Tomcat 没有提供有关指定共享加载程序的必要语法的文档...帮助...

问题是未将库添加到工件中。

To Fix, File-> Project Structure

要修复，File->Project Structure

then click Fix on all the errors that have been found, then click ok.

然后单击“修复所有已发现的错误”，然后单击“确定”。

Next time I ran the projects I encountered no errors.

下次我运行这些项目时，我没有遇到任何错误。

I had the same issue: When I build with maven, it ran well, but there was an error when running in the IDE by tomcat.

我遇到了同样的问题：当我使用maven构建时，它运行良好，但是在使用tomcat在IDE中运行时出现错误。

I think it is because the IDE cannot copy jar libraries to output folder, ie..WEB-INF/lib/ check it

我认为是因为IDE无法将jar库复制到输出文件夹，即..WEB-INF/lib/ 检查它

For me (a lazy method), just copy the missing jars to webapp/WEB-INF/lib/[ps: under the development directory, not the output one]

对我来说（一个懒人的方法），只需将丢失的jars复制到webapp/WEB-INF/lib/[ps：在开发目录下，而不是输出目录]
