Class Logger

java.lang.Object

io.vertx.core.logging.Logger

public class Logger
extends Object

<p>This class allows us to isolate all our logging dependencies in one place. It also allows us to have zero runtime 3rd party logging jar dependencies, since we default to JUL by default.</p>

<p>By default logging will occur using JUL (Java-Util-Logging). The logging configuration file (logging.properties) used by JUL will taken from the default logging.properties in the JDK installation if no java.util.logging.config.file system property is set. The vertx-java / vertx-ruby / etc scripts set java.util.logging.config.file to point at the logging.properties in the vertx distro install directory. This in turn configures vertx to log to a file in a directory called vertx-logs in the users home directory.</p>

<p>If you would prefer to use Log4J or SLF4J instead of JUL then you can set a system property called io.vertx.logger-delegate-factory-class-name to the class name of the delegate for your logging system. For Log4J the value is io.vertx.core.logging.impl.Log4JLogDelegateFactory, for SLF4J the value is io.vertx.core.logging.impl.SLF4JLogDelegateFactory. You will need to ensure whatever jar files required by your favourite log framework are on your classpath.</p>
