Question

我只是想关闭日志记录。我在文档中找到了这个： 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logback.xml文件。

有什么建议吗？

修改

我现在已将以下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：

Answer 1

查看类路径以查看您使用的日志记录实现。取决于你在那里找到的东西：

logback-classic.jar：添加logback.xml并将所有内容设置为日志级别WARN
log4j.jar：添加log4j.xml（或属性）并将所有内容设置为日志级别WARN

如果您只是看到slf4j-api，那么您可能想要添加一个slf4j-noop或其他东西。如果您看到slf4j-over-X，那么您将要将X配置为仅记录级别WARN。

Answer 2

我现在通过在我的代码中添加以下两行来解决问题：

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

如何关闭optaplanner中的日志记录？
