logback-splunk 无法实例化类型 com.splunk.logging.HttpEventCollectorLogbackAppender

问题描述 投票：0回答：1

我有一个运行 Java 17 ubuntu 的 splunk 日志设置。它使用 spring 框架，我将 logback splunk Appender 添加到项目中。构建docker镜像很好，但是spring boot 3.1.6应用程序无法启动。如果我删除 ，应用程序将启动，并在控制台上打印日志，因此 splunk 附加程序会出现问题。 logback-classic 和 logback-core 依赖项包含在 POM.xml 中。

logback-splunk.xml

<configuration>

    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

我通过添加 splunk 库解决了这个问题，

<!-- Splunk -->
<dependency>
    <groupId>com.splunk.logging</groupId>
    <artifactId>splunk-library-javalogging</artifactId>
    <version>1.11.2</version>
</dependency>
