在Spring Boot中配置log4j2.properties

Question

我是春靴的新手。我有一个跑步Spring靴项目。我想使用log4j2（由于项目限制，我必须使用log4j2本身）将不同级别的所有日志重定向到一个名为'test.log'的日志文件。

#rootLogger.appenderRefs = RollingFile
#rootLogger.appenderRef.stdout.ref = STDOUT

logger.rolling.name=org.hibernate.SQL
logger.rolling.level = debug

---我的测试API的控制器也有以下测试日志行：

    //Logger logger = LogManager.getLogger //is included       
logger.debug("This is a debug message");
logger.info("This is an info message");
logger.warn("This is a warn message");
logger.error("This is an error message");
logger.fatal("This is a fatal message");

---在我的理解中，我已经在代码中包含了所有必需的内容。但是我面临着这个问题--当我使用API时,只有hibernate调试记录器被添加到test.log中；我在controller中包含的五个测试日志（甚至其他使用的信息级日志）没有在test.log中记录；

控制台如下所示（控制台上显示了五个记录器中的两个，但这里也缺少信息级记录器）：

20:05:42.989 [http-nio-8000-exec-1] ERROR com.test.app.appController - This is an error message
20:05:42.994 [http-nio-8000-exec-1] FATAL com.test.app.appController - This is a fatal message
Hibernate: //used hibernate queries are displayed to console as needed

log4j2从.properties文件切换到了yaml或XML。您需要创建一个yaml或xml文件来加载log4j2。

示例：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<Configuration status="WARN">
    <Appenders>
        <Console name="ConsoleAppender" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{dd-MMM-yyyy HH:mm:ss.SSS} [%-5p] %m%n" />
        </Console>
        <RollingFile name="myapp" fileName="${sys:catalina.base}/logs/myapp.out"
            filePattern="${sys:catalina.base}/logs/myapp-%d{yyyy-MM-dd}.log.gz">
            <PatternLayout pattern="%d{dd-MMM-yyyy HH:mm:ss.SSS} [%-5p] %m%n" />
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="TRACE">
            <AppenderRef ref="ConsoleAppender" level="INFO"/>
            <AppenderRef ref="myapp" level="INFO"/>
        </Root>
    </Loggers>
</Configuration>
