Examples with Logger io.vertx.core.impl.logging.Logger used on opensource projects

Example 1 with Logger

use of io.vertx.core.impl.logging.Logger in project vert.x by eclipse.

the class CoreExamples method example18.

public void example18(String className, Exception exception) {
    // Note -these classes are Java only
    // You would normally maintain one static instance of Logger per Java class:
    Logger logger = LoggerFactory.getLogger(className);
    logger.info("something happened");
    logger.error("oops!", exception);
}

Example 2 with Logger

use of io.vertx.core.impl.logging.Logger in project vert.x by eclipse.

the class BareCommand method configureFromSystemProperties.

/**
 * This is used as workaround to retain the existing behavior of the Vert.x CLI and won't be executed
 * in other situation.
 */
