错误StatusLogger错误处理元素BatchDelivery（[appenders：null]）：CLASS_NOT_FOUND

Question

我试图将日志发送到弹性搜索，但是我的log4j2文件显示此错误。谁能帮我这个忙。预先感谢。

TestLogger.java

公共类TestLogger {

 private static final Logger logger = LogManager.getLogger(TestLogger.class);

    public static void main(String[] args) {

        logger.info("Hello World !");

        logger.info("Hello ElasticSearch !");
    }
}

log4j2.xml
