[logback-user] Variable substitution for logger name?

[Mark.Boatman at securian.com]

Is it possible to use variable substitution with the <logger name>?

Here is my configuration xml.  Everything works EXCEPT this:  <logger name
=${appLoggerPrefix} level="INFO">

Is that not allowed?

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

<configuration debug="true">
        <property resource=
"com/minnesotamutual/corp/compliance/end/config/app.properties" />
        <property name="LOGS_PATH" value=
"${com.minnesotamutual.appLogs}/${appName}/" />
        <property name="SPRING_LOG_BASE_FILENAME" value=
"${appName}-spring" />
        <property name="APP_LOG_BASE_FILENAME" value="${appName}-app" />
 
        <appender name="SpringLogFileAppender" class=
"ch.qos.logback.core.rolling.RollingFileAppender">
                <file>${LOGS_PATH}${SPRING_LOG_BASE_FILENAME}.log</file>
                <rollingPolicy class=
"ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                        <fileNamePattern>
${LOGS_PATH}${SPRING_LOG_BASE_FILENAME}-%d{yyyy-MM-dd}.log</
fileNamePattern>
                        <maxHistory>30</maxHistory>
                </rollingPolicy>
                <encoder>
                        <pattern>%date [%level] at line %line in 
%class[%method]: %msg%n</pattern> 
                </encoder>
        </appender>
 
        <appender name="AppLogFileAppender" class=
"ch.qos.logback.core.rolling.RollingFileAppender">
                <file>${LOGS_PATH}${APP_LOG_BASE_FILENAME}.log</file>
                <rollingPolicy class=
"ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                        <fileNamePattern>
${LOGS_PATH}${APP_LOG_BASE_FILENAME}-%d{yyyy-MM-dd}.log</fileNamePattern>
                        <maxHistory>30</maxHistory>
                </rollingPolicy>
                <encoder>
                        <pattern>%date [%level]: %msg%n</pattern> 
                </encoder>
        </appender>
 
        <logger name=${appLoggerPrefix} level="INFO">

        </logger>
 
        <logger name="org.springframework" level="INFO">

        </logger>
