如何关闭optaplanner中的日志？

Question

我只想关闭日志记录。我发现这在文档中： https://docs.jboss.org/optaplanner/release/6.2.0.Final/optaplanner-docs/html_single/index.html#logging

但是，我的项目没有一个logback.xml文件。

有什么建议吗？

编辑：

我现在已经添加了以下logback.xml文件到我的类路径的根目录：

<?xml version="1.0" encoding="UTF-8"?> 
<configuration debug="false"> 

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <!-- encoders are assigned the type 
     ch.qos.logback.classic.encoder.PatternLayoutEncoder by default --> 
    <encoder> 
     <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> 
    </encoder> 
    </appender> 

    <root level="warn"> 
    <appender-ref ref="STDOUT" /> 
    </root> 
</configuration> 

这些JAR文件都是我的类路径中：

• antlr-runtime-3.5.jar
• commons-codec-1.4.jar
• 公地IO-2.1.jar

Answer 1

看着你的类路径，看看你用什么日志实现。根据您发现有什么：

• 的logback-classic.jar：添加logback.xml并设置一切日志级别WARN
• log4j.jar：添加的log4j.xml（或属性）并设置就绪以日志级别警告

如果你只是看到slf4j-api，那么你可能会想要添加一个slf4j-noop或其他东西。如果您看到slf4j-over-X，那么您将需要将X配置为仅记录级别WARN。

现在我已经加入下面的两行我的代码解决了这个问题：

LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); 
loggerContext.stop();
