我将Tomcat与Eclipse一起使用。我最近升级到Neon，并在那里重新创建了我的Tomcat服务器配置。从那以后，我无法将我的 Web 应用程序正确记录到 Eclipse 控制台。具体来说，如果我在 Web 应用程序追加器中设置 INFO 级别，它们将成功转到日志文件，但不会转到控制台。
奇怪的是，只有当我将根级别从 WARN 更改为 INFO 时，控制台才会显示我的应用程序的 INFO 级别。但是，当然，这也将其他所有内容都放在了INFO，因此这不是很有用。
我也通过回落发送所有Tomcat日志记录。对于我的启动配置，我在参数中使用：
-Dcatalina.base="C:deveclipseworkspace.metadata.pluginsorg.eclipse.wst.server.coretmp0" -Dcatalina.home="C:devapache-tomcat-7.0.52" -Dwtp.deploy="C:deveclipseworkspace.metadata.pluginsorg.eclipse.wst.server.coretmp0wtpwebapps" -Djava.endorsed.dirs="C:devapache-tomcat-7.0.52endorsed" -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.jar和jul-to-slf4j-1.7.25.jar.
这是我的回点.xml：

这是我启动Tomcat时在Eclipse控制台中获得的输出：

此时，我加载了一个网页，该网页触发了带有 INFO 日志记录的目录类。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。
如果我将目录追加器更改为警告级别，日志文件会正确省略 INFO 消息。如前所述，如果我将目录追加器保留在 INFO并将根追加器更改为 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，但它没有帮助。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(它抑制了标准输出(，但对我在这里尝试做的事情没有好处。在设置错误之后，事情就成功了。
为什么它以前在 Luna 中起作用，但不是霓虹灯，谁知道呢。
