java - 按级别分隔logback日志

Question

是否可以单独记录每个级别，以便使用 Logback 获得 DEBUG.log、WARN.log、INFO.log...？

Answer 1

你可以写一个filter喜欢

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;

public class WarnFilter extends Filter<ILoggingEvent> {

    @Override
    public FilterReply decide(ILoggingEvent event) {
        if (Level.DEBUG.equals(event.getLevel())) {
            return FilterReply.ACCEPT;
        } else {
            return FilterReply.DENY;
        }
    }

}

然后用过滤器为它配置一个appender

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="logback.WarnFilter" />
    <encoder>
        <pattern>%date{yyyy-MM-dd HH:mm:ss.SSS} [%t] %p %c - %m [%class %M %L] %ex{full} %n</pattern>
    </encoder>
</appender>
