无法使用log4j2中的路由附加程序基于ThreadContext映射值创建多个日志文件 [英] Unable to create multiple log files based on the ThreadContext map values using routing appender in log4j2

问题描述

我在基于12c的oracle adf应用程序中使用log4j2 jar.

I'm using the log4j2 jars in the oracle adf application build on 12c.

要求:根据会话和动态更改日志记录属性的能力来创建多个日志文件.

Requirement: Create multiple log files based on the session and ability to change the logging properties dynamically.

Log4j2.xml文件

Log4j2.xml file

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" packages="apps.adfAppUI.ui.bean">
    <Appenders>
        <File name="file" fileName="./adfAppCustomLogs/TestLog4j2.log">

        <Routing name="AppRouting">

                <!-- This route is chosen if ThreadContext has value 'user' for key ROUTINGKEY. -->
                <Route key="USER">
                    <RollingFile name="Rolling-USER-${ctx:ROUTINGKEY}-${ctx:LOGGEDSESSIONID}" append="true" fileName="./adfAppCustomLogs/${ctx:ROUTINGKEY}-${ctx:LOGINID}-${ctx:LOGGEDSESSIONID}.log"

                        </Policies>
                    </RollingFile>
                </Route>
            </Routes>
        </Routing>
        <Async name="async" bufferSize="1000" includeLocation="true">
        <AppenderRef ref="AppRouting" />
    </Async>
    </Appenders>
    <Loggers>
        <Root level="trace">
            <!--<AppenderRef ref="file" level="DEBUG"/> -->
            <AppenderRef ref="async"/>
            <AppenderRef ref="STDOUT"/>
        </Root>
    </Loggers>
</Configuration>

我正在调用一个实用程序类，其中在登录后设置并清除了线程上下文值.

I'm calling an utility class where the threadcontext values are set and clearled after logging.

问题:即使我更改了每个会话的threadcontext值，我也看不到正在创建多个文件.所有日志都将附加到一个文件中.但是，当我重新启动服务器时，会生成一个新文件，并再次将所有会话日志附加到该文件.

Issue: Even though I change the threadcontext values for every session,I dont see multiple files being created. All the logs are appended to one file. But when I restart the server then a new file is generated and again all the session logs are being appended to it.

谢谢.

以下配置将用于该用例.

The below configuration will do the usecase.

<?xml version="1.0" encoding="UTF-8"?>
