在我们的项目中，我们计划使用SpringBoot2.0.9版本。我想知道SpringFramework2.0.9支持的Log4j2的更高版本是什么

mvn dependency:tree
gradle dependencies

这些命令将向您显示在将spring boot添加到pom或gradle文件时使用的依赖关系

SpringBoot对可以使用哪个版本的Log4j没有限制。spring-boot-starter-logging-log4j2预装了特定版本的log4j2。如果要使用较新的版本，请不要将spring-boot-starter-logging-log4j2作为依赖项，而是将log4j bom作为依赖项包含在依赖项管理中，然后包含要包含的特定log4j工件，而不要在依赖项上指定版本

例如：

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.apache.logging.log4j</groupId>
      <artifactId>log4j-bom</artifactId>
      <version>2.13.3</version>
      <type>pom</type>
    </dependency>
  </dependencies>
</dependencyManagement>
<dependencies>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
  </dependency>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
  </dependency>
</dependencies>
