无法创建类型为[com.sumologic.logback.SumoLogicAppender]的附录

Question

我正在使用Spring引导应用程序。当我尝试将https://github.com/SumoLogic/sumologic-logback-appender添加到我的项目并在logback.xml中添加配置时，如下所示

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="SumoAppender" class="com.sumologic.logback.SumoLogicAppender">
        <encoder>
            <Pattern>
                %date{ISO8601,UTC} [%t] %-5p %c - %m%n
            </Pattern>
        </encoder>
        <url>[collector-url]</url>
    </appender>
    <Logger name="SumoLogger" level="info">
        <appender-ref ref="SumoAppender" />
    </Logger>
</configuration>

我得到了下面的错误，无法继续

ERROR in ch.qos.logback.core.joran.action.AppenderAction - Could not create an Appender of type [com.sumologic.logback.SumoLogicAppender]. ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type com.sumologic.logback.SumoLogicAppender

任何帮助都是有用的

Answer 1

我找到了我的问题的答案。这是我的错。我正在使用log4j jar并查找logback类文件。我通过使用logback jar进行修正，如下所示

// https://mvnrepository.com/artifact/com.sumologic.plugins.logback/sumologic-logback-appender
implementation group: 'com.sumologic.plugins.logback', name: 'sumologic-logback-appender', version: '1.8'

Answer 2

我的预感是，您在运行时从类路径中丢失了sumologic-logback-appender jar。
