java logging API，禁用日志记录到标准输出 [英] java logging API, disable logging to standard output

问题描述

使用标准java日志API（导入java.util.logging.Logger），构造完成后：

Using the standard java logging API (import java.util.logging.Logger), after the construction:

Logger l = Logger.getLogger("mylogger");

我已经能够记录一些东西了。由于它没有FileHandler，因此它不会向磁盘写入任何内容。

I am already able to log something. Since it has not a FileHandler, it doesn't write anything to disk.

l.severe("test with no handler");

它将（有些，而不是全部）日志消息写入输出。
如何禁用此功能？
提前感谢

It writes (some, not all) the log messages to output. How can I disable this feature? thanks in advance Agostino

推荐答案

如果您不知道默认配置，则会出现问题java util logging。
建筑事实：
0）每个记录器的名称都是根记录器作为父记录器。
默认值：
1）logger属性useParentHandlers默认为true
2）根记录器默认有一个ConsoleHandler

The question arises if you don't know the default configuration of java util logging. Architectural fact: 0)Every logger whatever its name is has the root logger as parent. Default facts: 1) the logger property useParentHandlers is true by default 2) the root logger has a ConsoleHandler by default

所以。默认情况下，新的记录器也将其日志记录发送到他的父记录（点1），即根记录器（点0），默认情况下，将它们记录到控制台（点2）。

So. A new logger, by default sends its log records also to his parent(point 1) that is the root logger(point 0) wich, by default, logs them to console(point 2).

删除控制台日志记录很简单：

Remove console logging is easy as:

Logger l0 = Logger.getLogger("");
l0.removeHandler(l0.getHandlers()[0]);
