Question

以下是我将 slf4j 添加到我的 Akka 项目时得到的错误跟踪。

.....

知道如何解决这个问题吗？

Answer 1

这个问题可以通过将 akka-slf4j 依赖项添加到您的 Akka 项目来解决。

    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-actor_2.12</artifactId>
        <version>2.5.22</version>
    </dependency>
    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-slf4j_2.12</artifactId>
        <version>2.5.22</version>
    </dependency>

NOTE: Make sure your akka-actor and akka-slf4j have the same versions.
