java log4j INFO级别问题

Question

I am not sure what I could be doing wrong that causes info level messages not to appear. Here is the situation

 class LogTest {
      protected final Logger logger = Logger.getLogger(getClass());
      ...
      public void start() {
            logger.error(logger.isInfoEnabled());
               logger.info("blah");
      }
      ...
  }

Logger is not referenced anywhere else in the class.

Here is the output:

 ERROR 2010-02-18 09:14:01,489 com.company.test.Test - true

I do not know what else to check in order to get info working.. according to the logger it is enabled.

Answer 1

您可能拥有仅在WARN或更高版本上起作用的追加程序，或者可以配置了过滤器。

Answer 2

Be sure that you have set the appropriate logging level. Additionally, slf4j and/with logback are the newer and preferred logging libraries.

You can change the logging level by doing the following: logger.setLevel(Level.INFO);
