如何在春季只过滤特定的查询日志(logback.xml)

<appender name="QUERY" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>路径/查询日志.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <fileNamePattern>路径/查询日志-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <maxFileSize>10MB</maxFileSize>
        <maxHistory>30</maxHistory>
    </rollingPolicy>
    <encoder>
        <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
    <filter class="路径.QueryLogFilter" />
</appender>

package 路径;

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.spi.LoggingEvent;
import ch.qos.logback.core.filter.AbstractMatcherFilter;

public class QueryLogFilter extends AbstractMatcherFilter<Object> {

    @Override
    public FilterReply decide(Object event) {
        if (!isStarted()) {
            return FilterReply.NEUTRAL;
        }

        LoggingEvent loggingEvent = (LoggingEvent) event;
        String message = loggingEvent.getMessage();

        // 根据特定条件判断是否过滤该日志
        if (message.contains("特定查询关键词")) {
            if (loggingEvent.getLevel().equals(Level.INFO)) {
                return FilterReply.ACCEPT;
            }
        }

        return FilterReply.NEUTRAL;
    }
}

<filter class="路径.QueryLogFilter" />
