似乎 log4j 试图通过 XML 解析器解析 .json 配置文件，但为什么呢？

我通过命令行参数设置 log4j 配置文件：

-Dlog4j.configurationFile=src/log4j2.json

文件内容：

{
    "configuration": {
        "appenders": {
            "Console": {
                "name": "Console",
                "target": "SYSTEM_OUT",
                "PatternLayout": {
                    "pattern": "%date %thread %logger %message"
                }
            }
        },
        "loggers": {
            "root": {
                "level": "debug",
                "appender-ref": {
                    "ref": "Console"
                }
            }
        }
    }
}

我得到的：

[Fatal Error] log4j2.json:1:1: Content is not allowed in prolog.
