如何关闭optaplanner中的日志记录？

Question

我只想关掉记录。我在文档中发现了这一点：https://docs.jboss.org/optaplanner/release/6.2.0.Final/optaplanner-docs/html_single/index.html#logging

然而，我的项目没有回溯。xml文件。

有什么建议吗？

编辑：

我现在已经将以下logback.xml文件添加到类路径的根目录中：

<?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文件在我的类路径中：

• antlr-runtime-3.5。罐子
• commons-codec-1.4。罐子

这些是日志消息：

Answer 1

查看您的类路径以查看您使用的日志记录实现。根据您在那里找到的内容：

• 回归经典。jar：添加一个logback。xml并将所有内容设置为日志级别警告

如果你只是看到slf4j api，那么你可能会想添加一个slf4j noop或其他东西。如果看到slf4j-over-X，则需要将X配置为仅日志级别警告。

Answer 2

我现在已经通过在我的代码中添加以下两行来解决这个问题：

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