当 运行 来自 WAR 时，Logback 筛选 RollingFileAppender 不旋转
Logback sift RollingFileAppender not rotating when run from WAR
我有一个 logback 配置，可以记录到多个文件，包括名为 servernexus.log 的主日志文件。每个日志文件都应该由 RollingFileAppender 轮换。当我使用 logback 配置文件和我的 $CLASSPATH 中的所有其他内容从 eclipse 运行 时，servernexus.log 被 logback 正确旋转。当我 运行 从我的生产 WAR 文件日志记录工作但 servernexus.log 旋转永远不会发生。
这是 logback-server-win32event.xml:

我不是这方面的专家，但我认为这应该有助于找到问题。在配置中启用调试以检查 logback 并且您缺少 %i 。来自 logback 文档中 Appenders 的第 4 章
"除了"%d"之外还要注意"%i"转换令牌。%i和%d令牌都是强制性的。每次当前日志文件在当前时间段结束前达到maxFileSize时，它将从 0 开始以递增的索引进行归档。"
我终于明白了。 logback、slf4j 等 类 被码头加载了两次。解决方法是告诉码头将这些 类 视为系统 类:
WebAppContext.addSystemClasses(server, "org.slf4j.", "ch.qos.logback.", "org.apache.commons.logging.", "org.apache.log4j.", "org.codehaus.janino.");
这么简单吧？ :(
我有一个 logback 配置，可以记录到多个文件，包括名为 servernexus.log 的主日志文件。每个日志文件都应该由 RollingFileAppender 轮换。当我使用 logback 配置文件和我的 $CLASSPATH 中的所有其他内容从 eclipse 运行 时，servernexus.log 被 logback 正确旋转。当我 运行 从我的生产 WAR 文件日志记录工作但 servernexus.log 旋转永远不会发生。

我不是这方面的专家，但我认为这应该有助于找到问题。在配置中启用调试以检查 logback 并且您缺少 %i 。来自 logback 文档中 Appenders 的第 4 章
"除了"%d"之外还要注意"%i"转换令牌。%i和%d令牌都是强制性的。每次当前日志文件在当前时间段结束前达到maxFileSize时，它将从 0 开始以递增的索引进行归档。"
我终于明白了。 logback、slf4j 等 类 被码头加载了两次。解决方法是告诉码头将这些 类 视为系统 类:
WebAppContext.addSystemClasses(server, "org.slf4j.", "ch.qos.logback.", "org.apache.commons.logging.", "org.apache.log4j.", "org.codehaus.janino.");
这么简单吧？ :(
