Spring Actuator/Health Logger 设置为 OFF，但仍在记录

Question

我想在 application.properties 文件中将 /health 执行器端点的记录器设置为 OFF。应用程序基于 Spring Boot 1.5。/health 将是 F5 的新监控 URL。我不想淹没日志。我有这个。

    logging.level.org.springframework.web=DEBUG

    org.springframework.boot.actuate.health.Logger=OFF
    logging.level.org.springframework.boot.actuate.health=OFF

我仍然在控制台和日志文件中收到 DEBUG 日志记录。唯一有效的是将第一个设置为 INFO 或更高。但是，这是不可取的。所以，现在我明白了

2020-05-06 17:14:01.545 DEBUG 58588 --- [nio-9095-exec-5] o.s.web.servlet.DispatcherServlet        : DispatcherServlet with name 'dispatcherServlet' processing GET request for [/health]

我需要设置不同的记录器属性吗？对于不同的类/包？

我使用 logback，所以我为此添加了一个日志过滤器。您需要更改正则表达式以匹配您自己的日志记录格式。

package eu.stackoverflow.logging;

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;
import java.util.HashSet;
import java.util.Set;
import java.util.regex.Pattern;

public class IgnoringHealthAndPrometheusLoggingFilter extends Filter<ILoggingEvent> {

    private static final Pattern HEALTH_OR_PROMETHEUS =
        Pattern.compile("GET \"/(health|prometheus)\", parameters=\\{}");
    private static final Pattern COMPLETED =
        Pattern.compile("Completed 200 OK");

    private Set<String> activeThreads = new HashSet<>();

    @Override
    public FilterReply decide(ILoggingEvent loggingEvent) {
        if (isHealthOrPrometheus(loggingEvent.getMessage())) {
            activeThreads.add(loggingEvent.getThreadName());
            return FilterReply.DENY;
        } else if (isCompleted200Ok(loggingEvent.getMessage()) && activeThreads.remove(loggingEvent.getThreadName())) {
            return FilterReply.DENY;
        } else {
            return FilterReply.ACCEPT;
        }
    }

    private boolean isHealthOrPrometheus(String message) {
        return HEALTH_OR_PROMETHEUS.matcher(message).matches();
    }

    private boolean isCompleted200Ok(String message) {
        return COMPLETED.matcher(message).matches();
    }
}

    <appender class="ch.qos.logback.core.ConsoleAppender" name="CONSOLE">
        <filter class="eu.stackoverflow.logging.IgnoringHealthAndPrometheusLoggingFilter" />
    </appender>
