如何将Akka INFO日志记录输出"filter"到不同的文件？

Question

我正在记录"订单"上的信息和我正在使用Scala/Akka开发的交易应用程序生成的"交易"的信息。目前，所有输出都进入单个日志文件，但我希望信息转到单独的文件中。

我指定了我的application.conf如下...

akka {
  loggers = ["akka.event.slf4j.Slf4jLogger"]
  loglevel = "INFO"
  logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
}

。这是我logback.xml文件...

<configuration>
    <appender name="TRANSACTIONS" class="ch.qos.logback.core.FileAppender">
        <file>log/transactions.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="TRANSACTIONS" />
    </root>
    <appender name="ORDERS" class="ch.qos.logback.core.FileAppender">
        <file>log/orders.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="ORDERS" />
    </root>
</configuration>

我尝试修改我的logback.xml文件以包含过滤器，如下所示

<configuration>
    <appender name="TRANSACTIONS" class="ch.qos.logback.core.FileAppender">
        <filter class="domain.trading.DoubleAuctionMarket"/>
        <file>log/transactions.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="TRANSACTIONS" />
    </root>
    <appender name="ORDERS" class="ch.qos.logback.core.FileAppender">
        <filter class="domain.trading.Exchange"/>
        <file>log/orders.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="ORDERS" />
    </root>
</configuration>

但是，这会生成运行时错误...

14:11:38,361 |-ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [filter] of type [domain.trading.DoubleAuctionMarket] java.lang.ClassNotFoundException: domain.trading.DoubleAuctionMarket
at java.lang.ClassNotFoundException: domain.trading.DoubleAuctionMarket

和

14:11:38,417 |-ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [filter] of type [domain.trading.Exchange] java.lang.ClassNotFoundException: domain.trading.Exchange
at java.lang.ClassNotFoundException: domain.trading.Exchange

思潮？

[编辑：解决方案] 为了完整起见，我根据下面答案中提供的链接创建了两个过滤器TransactionsFilter和OrdersFilter，并将它们放在我项目的src/main/java/目录中。示例筛选器如下所示...

package filters;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.filter.Filter;
import ch.qos.logback.core.spi.FilterReply;
public class OrdersFilter extends Filter<ILoggingEvent> {
    @Override
    public FilterReply decide(ILoggingEvent event) {
        boolean isAskOrder = event.getFormattedMessage().contains("AskOrder");
        boolean isBidOrder = event.getFormattedMessage().contains("BidOrder");
        if ( isAskOrder || isBidOrder) {
            return FilterReply.ACCEPT;
        } else {
            return FilterReply.DENY;
        }
    }
}

然后，我编辑了我的logback.xml文件以引用新创建的过滤器...

<configuration>
    <appender name="TRANSACTIONS" class="ch.qos.logback.core.FileAppender">
        <filter class="filters/TransactionFilter"/>
        <file>log/transactions.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="TRANSACTIONS" />
    </root>
    <appender name="ORDERS" class="ch.qos.logback.core.FileAppender">
        <filter class="filters/OrderFilter"/>
        <file>log/orders.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="ORDERS" />
    </root>
</configuration>

在筛选器标记中指定的类不是要接受的文件类型，而是要用于筛选日志的筛选器类（可能是自定义类）的类路径。

所以我想你得到这个错误，因为你的类没有实现过滤器。

应在此处将筛选器类构建为可读的，每个筛选器一个，然后引用这些类。
