Question

我正在使用Mongodb Java Driver 3.4.0-beta及其＆＃39; org.mongodb.driver＆＃39;不断记录下面的消息：

对我来说这是无用的信息，而且冗长冗长。我几乎在stackoverflow中搜索了所有解决方案，但没有一个能为我工作。其中一个就像：

static {
  System.setProperty("DEBUG.MONGO", "false");
  System.setProperty("DB.TRACE", "false");
  LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
  Logger logger = context.getLogger("org.mongodb.driver.cluster");
  logger.setLevel(Level.OFF);
}

和

static {
  Logger logger = (Logger) LoggerFactory.getLogger("org.mongodb.driver.cluster");
  logger.setLevel(Level.OFF);
}

通过设置断点进行调试我发现它使用了logback作为Logger实现，但我无法获得驱动程序正在使用的真实记录器，所以我无法设置它日志级别。使用Logger logger = (Logger) LoggerFactory.getLogger("org.mongodb.driver.cluster");实际上并不起作用。它只是一直在退出。

我想知道：

如何避免这些消息？
为什么mongodb驱动程序会记录它？（它完全无用的信息）

Answer 1

请勿使用测试版，然后设置日志级别：

static {
  Logger logger = (Logger) LoggerFactory.getLogger("org.mongodb.driver.cluster");
  logger.setLevel(Level.WARN);
}

Answer 2

使用这一行

java.util.logging.Logger.getLogger("org.mongodb.driver").setLevel(java.util.logging.Level.SEVERE);

Mongodb的Java驱动程序会记录消息，如何禁用它？
