java - Mongodb Java 驱动程序不断记录消息，如何禁用它？

Question

我正在使用 Mongodb Java 驱动程序 3.4.0-beta，其“org.mongodb.driver”不断注销以下消息:

这对我来说是无用的信息，而且太冗长了。我已经搜索了 stackoverflow 中的几乎所有解决方案，但没有一个适合我。其中之一是这样的:

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作为记录器实现，但我无法获取驱动程序正在使用的真实记录器，因此我无法设置它的日志级别。使用Logger logger = (Logger) LoggerFactory.getLogger("org.mongodb.driver.cluster");实际上不起作用。它只是不断注销。

我想知道:

1. 如何避免出现这些消息？
2. 为什么 mongodb 驱动程序会记录它？(这是完全无用的信息)

Answer 1

不要使用测试版本然后设置它的日志级别:

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