logs - How to remove database information in log files

Question

Im using Spring iBatis Framework for my project. Then for logging im using logback. Then, upon checking the log files, I can see the database the system is using... I want to hide this for security purposes

Here is the sample log..

I want to remove the omstSpringManagedTransaction part

Answer 1

If you change the root logger to level to INFO , it will be applied to all packages ie, if you wanted to change the logging level for all packages, you can change the level at the root .

But, if you wanted to control only omstSpringManagedTransaction logging alone, then you can do that by adding a logger for that package as shown below:

<!-- set this level to WARN/ERROR upto your project -->
<logger name="o.m.s.t.SpringManagedTransaction" level="INFO" additivity="false">
    <appender-ref ref="STDOUT"/>
    <appender-ref ref="WINFILE"/>
</logger>

<!-- if you want add more loggers here for different packages -->    

<!-- this is for all other packages -->
<root level="debug">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="WINFILE" />
 </root>

Answer 2

Change your root log level to info. This means it will not print debugging logs.

<root level="info">
        <appender-ref ref="STDOUT" />
         <appender-ref ref="WINFILE" />
    </root>

Answer 3

<root level="info">

or add this in logback.xml

<logger name="o.m.s.t.SpringManagedTransaction" additivity="false">
  <level value="info"/>
  <appender-ref ref="STDOUT"/>
  <appender-ref ref="WINFILE"/>
</logger>
