ERROR StatusLogger No Log4j 2 configuration file found……

ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2

分析：
  他的意思是Log4j2.xml(或者什么properties)沒有找到，具體就是你的日志配置文件（可能是跟編譯器有關，不能自動編譯）
解決：
  只能手動將你的配置文件copy到編譯完成的目錄下邊

 如idea中:

    

 

//===========下邊這個是警告日志，沒啥事，看上邊===============

log4j:WARN No appenders could be found for logger (org.apache.htrace.core.Tracer).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

log4j2.xml的配置如下：可以參考，沒啥用：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="error" strict="true" name="XMLConfig">
    <Appenders>
        <!-- 類型名為Console，名稱為必須屬性 -->
        <Appender type="Console" name="STDOUT">
            <!-- 布局為PatternLayout的方式，
            輸出樣式為[INFO] [2018-01-22 17:34:01][org.test.Console]I'm here -->
            <Layout type="PatternLayout"
                    pattern="[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c{10}]%m%n" />
        </Appender>

    </Appenders>

    <Loggers>
        <!-- 可加性為false -->
        <Logger name="test" level="info" additivity="false">
            <AppenderRef ref="STDOUT" />
        </Logger>

        <!-- root loggerConfig設置 -->
        <Root level="info">
            <AppenderRef ref="STDOUT" />
        </Root>
    </Loggers>

</Configuration>
