Spring 带有 Log4j2 的 Webflux
Spring Webflux with Log4j2
关于 Spring Webflux 和 Log4j2 组合的快速问题。
出于组织原因，我 必须 使用 Spring Webflux 和 log4j2。如果在项目中看不到 log4j2.xml，我们的支持团队甚至会拒绝支持该应用程序。
拜托，我的问题不是挑战这一点，我喜欢我的支持团队，也喜欢制定这条规则的人。我带着一个真正的问题来到这里，不管上面如何，为什么我的应用程序不是 log4j2？
也就是说，我可以在启动时看到它。
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.13.3/log4j-slf4j-impl-2.13.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
此外，我在任何地方都看不到我的日志文件。 （但在 IntelliJ 上，我确实在控制台上看到了日志）
这是我的 log4j2.xml、我的 pom.xml 和一个虚拟启动应用程序。三者结合可以重现问题。

我该怎么做才能使我的应用程序成为 log4j2？
有什么办法可以查看实际的日志文件？使 SLF4J 消息消失？
是否可以解决这个问题而不必在 pom 中到处添加排除项？
感谢您的帮助。
只需在 Maven pom.xml 中从 spring-boot-starter-webflux 依赖项中排除 spring-boot-starter-logging 并添加 spring-boot-starter-log4j2.
与此处描述的类似：https://www.baeldung.com/spring-boot-logging#log4j2-configuration-logging
关于 Spring Webflux 和 Log4j2 组合的快速问题。 出于组织原因，我 必须 使用 Spring Webflux 和 log4j2。如果在项目中看不到 log4j2.xml，我们的支持团队甚至会拒绝支持该应用程序。
拜托，我的问题不是挑战这一点，我喜欢我的支持团队，也喜欢制定这条规则的人。我带着一个真正的问题来到这里，不管上面如何，为什么我的应用程序不是 log4j2？
也就是说，我可以在启动时看到它。
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.13.3/log4j-slf4j-impl-2.13.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
此外，我在任何地方都看不到我的日志文件。 （但在 IntelliJ 上，我确实在控制台上看到了日志）
这是我的 log4j2.xml、我的 pom.xml 和一个虚拟启动应用程序。三者结合可以重现问题。

然后我开始我的应用程序：

我该怎么做才能使我的应用程序成为 log4j2？ 有什么办法可以查看实际的日志文件？使 SLF4J 消息消失？ 是否可以解决这个问题而不必在 pom 中到处添加排除项？ 感谢您的帮助。
只需在 Maven pom.xml 中从 spring-boot-starter-webflux 依赖项中排除 spring-boot-starter-logging 并添加 spring-boot-starter-log4j2.
与此处描述的类似：https://www.baeldung.com/spring-boot-logging#log4j2-configuration-logging
