I have a co-worker who is trying to get log4j to behave as follows:
Log to Stdout
By default, disable most output
Show only messages from
java.sql.PrepareStatement at level debug and up
He's getting caught up in the 'level' vs 'priority'. Here is his config file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "D:/Java/apache-log4j-1.2.15/src/main/resources/org/apache/log4j/xml/log4j.dtd" >
<log4j:configuration>
<!-- Appenders -->
<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%5p %d{ISO8601} [%t][%x] %c - %m%n" />
</layout>
</appender>
<!-- Loggers for ibatus and JDBC database -->
<logger name="
java.sql.PreparedStatement">
<level value="debug"/>
</logger>
<!-- The Root Logger -->
<root>
<level value="error"/>
<appender-ref ref="stdout"/>
</root>
</log4j:configuration>
The output from this shows no messages in the log output.
How does he need to change his log4j.xml config file to make it behave as he's expecting?
