Spring Boot和Logback:禁用记录器 [英] Spring Boot and Logback: Disable a logger

问题描述

使用Spring Boot 1.4和Logback，我在 application.yml 中配置日志记录:

Using Spring Boot 1.4 together with Logback, I configure the logging in the application.yml:

logging:
  level:
    org.hibernate.SQL: INFO
    com.netflix.eureka: OFF

请注意，第二种配置的建议直接来自 Spring Cloud Service注册和发现文档.它适用于 INFO 和其他正常"级别.但是，日志还会显示(由我重新格式化):

Note that the recommendation for the second configuration comes straight from the Spring Cloud Service Registration and Discovery documentation. It works quite well for INFO and other ‘normal’ levels. However, the log also shows (reformatted by me):

… o.s.cloud.logging.LoggingRebinder        : Cannot set level: false for
        'org.hibernate.engine.internal.StatisticalLoggingSessionEventListener'

现在， false 是一个非常有趣的级别，不是吗?如何完全禁用记录器?

Now, false is a very interesting level, isn’t it? How can I disable a logger completely?

推荐答案

yaml-parser将 OFF 和 ON 解释为 Boolean 因此将 false 或 true 传递给日志记录框架.如果要禁用级别为 OFF 的日志记录，则需要将属性的值设置为 String ，这可以通过单引号将其实现.您的示例已修改:

The yaml-parser interprets the words OFF and ON as Boolean and so passes false or true to the logging framework. If you want to disable logging with the level OFF you need to set the value of the property as a String which can be achieved by single quotes. Your example modified:

logging:
  level:
    org.hibernate.SQL: INFO
    com.netflix.eureka: 'OFF'
