JOOQ Log4j - missing console output

Question

I have a problem with logging as it is described here.

My code:

Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url, userName, password);

Settings settings = new Settings();
settings.withRenderFormatted(true);
settings.setExecuteLogging(true);

DSLContext dslContext = DSL.using(conn, SQLDialect.MYSQL,  settings);


dslContext.select(USER.USERID, USER.IMIE, USER.NAZWISKO).from(USER).orderBy(USER.USERID).limit(1, 2).fetch();

And I have nothing in my console

This is my log4j.xml:

<?xml version="1.0" encoding="UTF-8"?>
<log4j:configuration>
    <appender name="stdout" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%m%n" />
        </layout>
    </appender>

    <root>
        <priority value="debug" />
        <appender-ref ref="stdout" />
    </root>
</log4j:configuration>

and my IVY dependencies:

<dependency org="org.jooq" name="jooq" rev="3.2.2"/>
<dependency org="org.jooq" name="jooq-codegen" rev="3.2.2"/>
<dependency org="org.jooq" name="jooq-meta" rev="3.2.2"/>

<dependency org="mysql" name="mysql-connector-java" rev="5.1.26"/>
<dependency org="log4j" name="log4j" rev="1.2.16"/>
<dependency org="org.slf4j" name="slf4j-simple" rev="1.7.4"/>

Answer 1

As far as I could read the code (cf org.jooq.tools.JooqLogger), Jooq is guessing the logger to use by trying to load each ones until it succeeds. Considering you ivy.xml, you have both Log4j and slf4j-simple. And Jooq is trying slf4j first. So Log4j is not used.

So you need to remove slf4j-simple from your dependencies.

If you do require a slf4j logger, try slf4j-log4j12, which redirects slf4j logs into log4j.

Nicolas, You are the Boss : ) and You were right

this is proper dependencies,on IVY:

<dependency org="org.jooq" name="jooq" rev="3.2.2"/>
<dependency org="org.jooq" name="jooq-codegen" rev="3.2.2"/>
<dependency org="org.jooq" name="jooq-meta" rev="3.2.2"/>

<dependency org="mysql" name="mysql-connector-java" rev="5.1.26"/>
<dependency org="log4j" name="log4j" rev="1.2.16"/>
<dependency org="org.slf4j" name="slf4j-log4j12" rev="1.7.5"/>
