我更改了日志版本并尝试了不同的依赖项

如果日志后端创建了日志文件，但其中没有消息出现，最常见的原因是：消息正在被记录到另一个后端。

在您的情况下，您有以下日志记录依赖项（参见 

mvn dependency:list
或您的 IDE）：

[INFO] 
[INFO] --- dependency:2.8:list (default-cli) @ log4j-sandbox ---
[INFO] 
[INFO] The following files have been resolved:
          ...
[INFO]    commons-logging:commons-logging:jar:1.1.1:compile
          ...
[INFO]    org.apache.logging.log4j:log4j-api:jar:2.19.0:compile
[INFO]    org.apache.logging.log4j:log4j-core:jar:2.17.0:compile
          ...
[INFO]    org.slf4j:jcl-over-slf4j:jar:1.6.1:compile
[INFO]    org.slf4j:jul-to-slf4j:jar:1.6.1:compile
[INFO]    org.slf4j:log4j-over-slf4j:jar:1.6.1:compile
[INFO]    org.slf4j:slf4j-api:jar:1.6.1:compile
          ...

它们具有以下目的：

  • commons-logging
    、
    log4j-api
    和 
    slf4j-api
    是正确的日志记录 API：您的代码或库代码直接使用它们，
  • log4j-over-slf4j
    是 
    log4j:log4j
    (Log4j 1.x) 的替代品，其中包含 API 和后端。该工件仅替换 API 并将所有消息转发到 SLF4J。
  • log4j-core
    是一个日志后端：Log4j API 将使用它来写入消息。
  • slf4j-api
    还有一个无操作后端：如果选择它，您将得到一个 像这样的消息 问题关于你的 控制台。
    • 其余的是API之间的各种桥梁。
查看您的依赖关系：

    使用 Log4j API 编写的代码将正确记录到 Log4j Core，
    • 使用 SLF4J 编写的代码将被记录到
  • NO-OP 后端（类路径上不存在其他 SLF4J 实现），
    • 使用 Commons Logging 编写的代码将被重定向到 SLF4J（通过
  • jcl-over-slf4j
     或
    log4j-over-slf4j
    ）。
要修复您的日志堆栈，您应该：

    升级
  • commons-logging
    到版本1.3.0（直接支持Log4j API和SLF4J，优先考虑前者），
    • 删除
  • jcl-over-slf4j
    ,
    • 尝试删除
  • log4j-over-slf4j
    ：一些
    旧库可能仍然直接使用Log4j 1.x，但这不太可能。如果您开始收到有关 org/apache/log4j/Logger 的运行时链接错误，则需要再次添加依赖项，
    在 SLF4J 和 Log4j API 之间添加一座桥梁：在您的情况下，它是 
    • log4j-slf4j-impl
  • （参见
    这个问题
    ）。


备注：
 jul-to-slf4j 工件可用于提供 
java.util.logging
 和 SLF4J 之间的重定向。但是，与其他重定向不同，这只能针对整个应用程序服务器“全局”完成，或者需要应用程序服务器特定配置。因此 
jul-to-slf4j
 在 WAR 文件中通常是无用的。
