Log4j2-写入以XML声明的特定记录器

时间：2019-06-10 12:06:37

标签： java logging log4j2

我试图配置Log4j2几个小时，但无法解决此问题。

我想在我的应用程序中使用两个单独的记录器（每个类都可以使用两个记录器）。一个记录器的行为类似于默认（在某处记录），但是第二个记录器仅收集一些数据。

现在我有这样的想法：

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

...

private static final Logger logger = LogManager.getLogger(ProductAttributesVerifier.class);
private static final Logger validationLoger = LogManager.getLogger("validation");

...

logger.warn("Started validation (in basic logger)");
validationLoger.info("INF Started validation of \"" + product.name + "\"");
validationLoger.warn("WRN Started validation of \"" + product.name + "\"");
validationLoger.error("ERR Started validation of \"" + product.name + "\"");

validationLogger中的内容必须转到另一个文件（logger中的内容无法显示。

我的log4j2.xml（位于项目的根目录中）：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
        <File name="validation" fileName="validation.log">
            <PatternLayout pattern="%d %p %c{1.} [%t] %m %ex%n"/>
        </File>
    </Appenders>
    <Loggers>
        <Logger name="validation" level="warn">
            <AppenderRef ref="validation"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

不幸的是，没有出现文件'validation.log'，并且所有日志都被打印到控制台中。我在做什么错了？

您需要对控制台和文件使用多个追加程序。

答案 1 :(得分：-1)

我的配置（有问题）是正确的。

重新启动计算机（和Eclipse IDE）后，一切都开始正常工作。不幸的是，我不知道为什么，但是我会将这个答案发布给以后的读者。
