自定义服务器日志路径

1. controller 中使用

@RestController
@RequestMapping("/question")
@Slf4j
public class QuestionController {
    private final static String LOGGER = "recommendFeedBackLog";
    /**
     * 推荐试题反馈使用的日志
     */
    private final static Logger FEEDBACKLOG = LoggerFactory.getLogger(LOGGER);
}

2. 增加日志过滤器

public class RecommendLogFilter extends Filter<ILoggingEvent> {
    @Override
    public FilterReply decide(ILoggingEvent event) {
        if (event.getLoggerName() != null && (event.getLoggerName().equals("recommendFeedBackLog"))) {
            return FilterReply.ACCEPT;
        }
        return FilterReply.DENY;
    }
}

1. 在 logkback.xml 中配置

<appender name="recommendFeedBackLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <filter class="com.tal.storage.core.log.RecommendLogFilter"/>
    <file>${catalina.base}/logs/cloud-storage/recommend/cloud-storage_recommend_log.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${catalina.base}/logs/cloud-storage/recommend/cloud-storage_recommend_log.%d{yyyy-MM-dd}.log</fileNamePattern>
        <maxHistory>100</maxHistory>
    </rollingPolicy>
    <encoder>
        <pattern>%msg%n</pattern>
    </encoder>
</appender>

也可以用这种方式：

/**
 * 定义logger，用于收集发送失败MQ消息
 */
public class SendMessageFailFilter extends AbstractMatcherFilter<ILoggingEvent> {
    private String loggerName;
    private Level level;
    /**
     * DENY    立即删除日志事件而不咨询剩余的过滤器
     * NEUTRAL    查询列表中的下一个过滤器，如果没有其他过滤器可供参考，则会正常处理日志记录事件
     * ACCEPT    立即处理日志事件，跳过其余过滤器的调用
     *
     * @param event
     * @return
     */
    @Override
    public FilterReply decide(ILoggingEvent event) {
        if (event.getLoggerName().contains(loggerName) && level == event.getLevel()) {
            return onMatch;
        }
        return onMismatch;
    }
    public void setLoggerName(String loggerName) {
        this.loggerName = loggerName;
    }
    public void setLevel(Level level) {
        this.level = level;
    }
}

<!-- 自定义日志输出器 -->
    <appender name="tableData" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="com.tal.log.filter.SendMessageFailFilter">
            <loggerName>table-data</loggerName>
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
        <file>${catalina.base}/logs/database-data-collection/table-data.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>
                ${catalina.base}/logs/database-data-collection/table-data.%d{yyyy-MM-dd}.log
            </fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %logger{50}[%M][%L] - %msg%n</pattern>
        </encoder>
    </appender>
