New Maven dependcy turns on jOOQ logging

Question

Recently I've added new dependency to project for generating .xls file.

pom.xml

    <dependency>
      <groupId>org.jxls</groupId>
      <artifactId>jxls</artifactId>
      <version>2.0.0</version>
    </dependency>
    <dependency>
      <groupId>org.jxls</groupId>
      <artifactId>jxls-poi</artifactId>
      <version>1.0.0</version>
    </dependency>

Code

 public StreamingOutput createStreamedExcelReport(Map<String, Object> params, String templateName, String[] columnsToHide) throws Exception {
        try(InputStream is = ReportGenerator.class.getResourceAsStream(templateName)) {
            assert is != null;
            final Transformer transformer = PoiTransformer.createTransformer(is);
            AreaBuilder areaBuilder = new XlsCommentAreaBuilder(transformer);
            List<Area> xlsAreaList = areaBuilder.build();
            Area xlsArea = xlsAreaList.get(0);
            Context context = new PoiContext();
            for(Map.Entry<String, Object> entry : params.entrySet()) {
                context.putVar(entry.getKey(), entry.getValue());
            }
            xlsArea.applyAt(new CellRef("Sheet1!A1"), context);
            xlsArea.processFormulas();
            return new StreamingOutput() {
                @Override
                public void write(OutputStream out) throws IOException {
                    ((PoiTransformer) transformer).getWorkbook().write(out);
                }
            };
        }
    }

Unfortunately it turns on probably jOOQ debug logging which is really bad because it logs all db queries. Application is making big query for .xls, so it shouldn't log that (~1,5GB output in 3min).

Example of logs

Thorough fix via logging configuration

jOOQ by default uses debug logging via whatever of these three logging frameworks it first discovers on the class path: slf4j, log4j, java.util.logging. The jxls library has a dependency on logback via slf4j as can be seen in its pom.xml:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.12</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.12</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.1.3</version>
</dependency>

In order to turn off jOOQ debug logging, you should configure your logging frameworks (in this case: logback) accordingly.

Quick fix in jOOQ:

You can also turn off most logging in jOOQ directly by specifying:

Settings.withExecuteLogging(false);
