No, a logger can be named anything at all.
As a convenience, a Class can be passed in which case the name =
class.getName(). Log objects don't have to have names which match the
class they are used by, but it's a very common convention.
In 99% of cases, when loggers are created they are created by passing a
Class object, ie have name of the class that created them.
package example.foo;
public Widget {
// log has name(aka category) of example.foo.Widget
private Log log = LogFactory.getLog(Widget.class);
// special log object for issuing messages that can be
// filtered/written using rules different from the ones
// for class-specific log messages.
private Log sysAdminLog = LogFactory.getLog("sysadmin-alerts");
}
