LOG4J2: Disable "No log4j2 configuration file found.." print when configuring programmatically
提问by Excite
I am not using any XML configuration file, rather I am setting the logger configuration programmatically. The logger works correctly but just when I call the first line of the code below, a warning ERRORmessage shows up to tell me that the configuration file was not found and default configuration will be used.
我没有使用任何 XML 配置文件，而是以编程方式设置记录器配置。记录器工作正常，但是当我调用下面代码的第一行时，会ERROR显示一条警告消息，告诉我未找到配置文件，将使用默认配置。
But I don't want this message to be displayed on the console every time I rung the program because I will programmaticallyadd the configuration myself.
但是我不希望每次运行程序时都在控制台上显示此消息，因为我会自己以编程方式添加配置。
The message:
消息：
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.
It comes when I call the code below:
当我调用下面的代码时会出现：
LoggerContext context = (LoggerContext) LogManager.getContext(false);
Or if I get the root logger first:
或者，如果我先获得根记录器：
Logger logger = LogManager.getLogger(LogManager.ROOT_LOGGER_NAME);
Is there some kind of property that I can set to disable this message from being displayed? Or another approach?.
是否有某种属性可以设置为禁止显示此消息？还是另一种方法？
NOTE: I disabled another notification regarding Log4j2 JMX by setting the property -Dlog4j2.disable.jmx=true. But I couldn't find for this one.
注意：我通过设置属性禁用了另一个关于 Log4j2 JMX 的通知-Dlog4j2.disable.jmx=true。但是我找不到这个。

Add the following system property in order to not show that message:
添加以下系统属性以不显示该消息：
-Dorg.apache.logging.log4j.simplelog.StatusLogger.level=OFF
Alternatively, and more simply:
或者，更简单的是：
import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.status.StatusLogger;
...
StatusLogger.getLogger().setLevel(Level.OFF);

You can simply do this in your main class.
您可以在主类中简单地执行此操作。
static {
StatusLogger.getLogger().setLevel(Level.OFF);
}

You have to implement initialize method for proper initialization of log4j configurations from code.
您必须实现 initialize 方法才能从代码正确初始化 log4j 配置。
Check the "How do I configure log4j2 in code without a configuration file" section in below page which provides the source code also.
检查下面页面中的“如何在没有配置文件的情况下在代码中配置 log4j2”部分，该部分还提供了源代码。
