在 Spring 使用 maven 启动时升级 log4j

Question

我正在尝试升级我的 spring 引导项目中的 log4j 库：

问题是 maven 下载了 log4j-bom 2.14.1 版：

Answer 1

您正在使用 spring 引导父版本 2.5.1，这就是它在构建期间默认下载 log4j 2.14.1 的原因。与您的 pom.xml 中的任何其他依赖项没有其他冲突，因此请尝试最新的 spring boot starter-parent 版本。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.2</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>
