Log4j2无法加载自定义ConsoleLogConverter与SocketLogResolverFactory插件

我正尝试为Log4j2添加两个自定义插件ConsoleLogConverter和SocketLogResolverFactory，用于实现日志脱敏功能，但应用启动时Log4j2无法加载这些插件，尽管它们的位置和注解都配置正确。

环境信息 #

• Log4j2版本：2.24
• Java版本：17
• 框架：Spring Boot 3.3.2
• 构建工具：Maven

已尝试操作 #

• 创建log4j2.plugins文件和log4j2.component.properties文件
• 最初Log4j2Plugins.dat仅存在于target目录，之后添加Maven配置将其从target复制到resources目录，但转换器仍未注册

已完成的检查项 #

1. 确认ConsoleLogConverter和SocketLogResolverFactory类所在包正确，且使用@Plugin注解
2. 确保log4j2.xml配置文件在启动时加载
3. 检查@Plugin和@PluginFactory注解来自正确的Log4j包
4. 排查pom.xml中Log4j2与其他库的版本冲突
