Question

我正在尝试以JSON格式输出所有日志事件。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
        <pattern>%d{yyyy-MM-dd'T'HH:mm:ss.SSSZ} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>
<root level="INFO">
    <!--<appender-ref ref="kafkaAppender" />-->
    <appender-ref ref="STDOUT" />
</root>

Maven依赖项：

   <dependency>
        <groupId>net.logstash.logback</groupId>
        <artifactId>logstash-logback-encoder</artifactId>
        <version>4.7</version>
    </dependency>

运行此配置时看到错误。我有什么想念吗？

这是堆栈跟踪：

在使用4.7版本的logstash-logback-encoder时遇到了相同的错误，并且升级到4.11解决了该问题。
