如何关闭MarkLogic Java API日志记录？

Question

I have trouble turning off MarkLogic log messages like these when uploading files to MarkLogic database through Java API:

16:24:01.599 [main] INFO  com.marklogic.client.io.DOMHandle - Serializing DOM document to output stream

I followed the information in MarkLogic Java API documentation about logging MarkLogic Java API documentation . Here is how I initialize database client and xmlDocMgr:

databaseClient = DatabaseClientFactory.newClient(marklogicHost, marklogicPort, marklogicUser, password, Authentication.DIGEST);

ByteArrayOutputStream out = new ByteArrayOutputStream();
RequestLogger logger = databaseClient.newLogger(out);
logger.setEnabled(false);

xmlDocMgr = databaseClient.newXMLDocumentManager();
xmlDocMgr.stopLogging();

What am I doing wrong? How to disable log messages?

Thanks in advance!

Answer 1

Based on the docs, I believe you need to call "xmlDocMgr.startLogging(logger)" first, which will register the RequestLogger with xmlDocMgr.

The "stopLogging" call doesn't do anything based on what's in the docs:

"If called on a manager not currently logging, nothing happens, not even an error or exception."

Answer 2

The documentation section you referenced is unrelated--it's a different kind of logging you could use.

What you're seeing is that MarkLogic Java API uses SLF4J for logging, and you should configure it with your perferred logging framework. In the current release (3.0.6) we include logback which automatically enables the logging you're seeing. We removed logback from future releases since it's not really required, and the SLF4J philosophy is to allow you to choose your preferred logging framework.

In any case, assuming you'd like to keep logback. Add a file named "logback.xml" to your classpath with the level set to "WARN" as in the following suggested contents:

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="WARN">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>

I commented out the following section in POM to disable the log output.

<!--        <dependency>
        <groupId>com.marklogic</groupId>
        <artifactId>java-client-api</artifactId>
        <version>3.0.6</version>
    </dependency>-->
