在Tomcat8中运行spring boot 2.4.0应用程序时遇到启动问题。Spring-boot-starter-log4j2 2.4.0加载log4j 2.13.3。这个问题只有在作为web应用程序运行时才会重现，当我从命令行运行相同的代码时，一切都使用相同的库版本和配置。我使用的是自定义的yaml配置文件。你知道为什么会发生这个错误吗？

用于添加的修复

代码语言：javascript
复制
<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-yaml</artifactId>
</dependency>

失败的方法是

代码语言：javascript
复制
@Override
protected ObjectMapper getObjectMapper() {
    return new ObjectMapper(new YAMLFactory()).configure(JsonParser.Feature.ALLOW_COMMENTS, true);
}

类路径中没有YAMLFactory
