我在 Eclipse 中使用 Tomcat。我最近升级到 Neon 并在那里重新创建了我的 Tomcat 服务器配置。从那时起，我就无法将我的 Web 应用程序正确地记录到 Eclipse 控制台。具体来说，如果我在 Web 应用程序附加程序中设置了 INFO 级别，它们将成功进入日志文件，而不是控制台。

奇怪的是，只有当我将 ROOT 级别从 WARN 更改为 INFO 时，控制台才会显示我的应用程序的 INFO 级别。但当然，这也将其他所有内容都放在 INFO 中，这使得它不是很有用。

我也通过 logback 发送所有 Tomcat 日志记录。对于我的启动配置，我在参数中使用：

-Dcatalina.base="C:\dev\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0" -Dcatalina.home="C:\dev\apache-tomcat-7.0.52" -Dwtp.deploy="C:\dev\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps" -Djava.endorsed.dirs="C:\dev\apache-tomcat-7.0.52\endorsed" -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager" -Djava.util.logging.config.file="C:/dev/apache-tomcat-7.0.52/conf/logging.properties" -Ddeployment.security.SSLv2Hello=false -Ddeployment.security.SSLv3=false -Ddeployment.security.TLSv1=false -Ddeployment.security.TLSv1.1=true -Ddeployment.security.TLSv1.2=true -Dlogback.configurationFile="C:/dev/apache-tomcat-7.0.52/lib/logback.xml"

在类路径中，我添加了tomcat-juli.jarand jul-to-slf4j-1.7.25.jar。

这是我的 logback.xml：

<?xml version="1.0" encoding="UTF-8"?>

        </rollingPolicy>
    </appender>

  <!-- If desired, we can create a class logger with additivity false to put that in its own log file -->

  <!-- be quiet -->
  <logger name="org.apache.struts2.util.TokenHelper" level="ERROR" />
  <logger name="org.dbunit.dataset.AbstractTableMetaData" level="ERROR"/>

  <logger name="org.w3c.tidy" level="OFF"/>

  <root level="WARN">

</configuration>

此时，我加载了一个网页，该网页使用 INFO 日志记录触发 Catalog 类。它成功登录到上面列出的tomcat7.log 文件。但它不会出现在控制台中。

如果我将目录附加程序更改为 WARN 级别，则日志文件会正确遗漏 INFO 消息。如前所述，如果我将目录附加程序留在 INFO并将ROOT 附加程序更改为 INFO，它将与其他所有内容一起显示在控制台中。

我已经升级到最新版本的 logback 和 slf4j 并没有帮助。任何帮助表示赞赏。

我能够解决这个问题。

我有一个自定义context.xml作为我的 Eclipse Tomcat 服务器配置的一部分。它具有属性，swallowOutput="true"。这对生产机器有好处（它抑制标准输出），但不适用于我在这里尝试做的事情。设置为 false 后，一切正常。

为什么它以前在 Luna 中有效，但在 Neon 中无效，谁知道呢。
