将log4j2日志级别从字符串更改为int

Question

within the log4j2 configuration I am trying to convert the loglevels from string to an int.

Following the directions located in log4j2 Patterns section

image snippet of example log4j2 pattern mapping

Following the example above I created in log4j2.xml config:

    <JMS name="jmsQueue" 
destinationBindingName="${sys:env}.logging" 
factoryName="org.apache.activemq.jndi.ActiveMQInitialContextFactory"
factoryBindingName="ConnectionFactory"
providerURL="${sys:log4j.providerurl}"
userName="log"
password="log">
    <PatternLayout pattern='{"Message":"%m","LogLevel":%level{Debug=1,Info=2,Warn=3,Error=4,Fatal=5,Trace=6},"Type":"middleware","App":"${app_name}","Env":"${sys:env}","data":{"Event_Time":"%d{ISO8601}","Thread":"%t","Class":"%c"}}'/>
</JMS>

The edited PatternLayout I would now expect would replace the string debug,info,warn etc. with the mapped int values of 1,2,3 . .

This is not the case, I still receive string value. If someone could suggest where I am making the mistake I would appreciate it. thank you.

I've tested your pattern but it worked well.

Here's my log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout
                    pattern='{"Type":"middleware","Env":"${sys:env}","App":"${app_name}","LogLevel":%level{Debug=1,Info=2,Warn=3,Error=4,Fatal=5,Trace=6},"Message":"%m","data":{"Event_Time":"%d{ISO8601}","Thread":"%t","Class":"%c"}}'/>
        </Console>
    </Appenders>

    <Loggers>
        <Root level="DEBUG">
            <AppenderRef ref="STDOUT"/>
        </Root>
    </Loggers>
</Configuration>

And here's the output:

{"Type":"middleware","Env":"${sys:env}","App":"${app_name}","LogLevel":2,"Message":"b","data":{"Event_Time":"2017-03-29T11:28:14,477","Thread":"main","Class":"test.Log4j2"}}
