Scala 如何"；“过滤器”；Akka信息记录输出到不同的文件？

我正在记录使用Scala/Akka开发的交易应用程序生成的“订单”和“交易”信息。目前，所有的输出都进入一个日志文件，但我希望信息进入单独的文件

我已经指定了我的

application.conf

，如下所示

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

…这是我的

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>

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

及

想法

[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

TransactionFilter

和

OrdersFilter

，并将它们粘贴在我项目的

src/main/java/

目录中。示例过滤器看起来像

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;
        }
    }
}

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

因此，我猜您会遇到这个错误，因为您的类没有实现过滤器

---

您应该将过滤器类构建为可读的，每个过滤器一个，然后引用它们。

这对您有用吗？
