Logstash-Logback编码器：“IllegalAccesserror：无法访问类[…]”

Question

我尝试使用Logstash tcp套接字追加器将日志从java应用程序发送到Logstash。java应用程序。已经可以使用logback 1.1.9(slf4j)和其他追加器。

现在，我将以下行添加到logback-test.xml中：

<configuration>
    <appender name="logstash" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
        <destination>[IP]:5010</destination>
        <encoder class="net.logstash.logback.encoder.LogstashEncoder">
            <fieldNames>
                <message>log_msg</message>
            </fieldNames>
        </encoder>
        <keepAliveDuration>5 minutes</keepAliveDuration>
    </appender>

<root>
<level value="info"/>
<appender-ref ref="logstash" />
</root>
</configuration>
