Spring boot 带嵌入式tomcat的Spring引导应用程序，将访问日志发送到syslog

我有一个spring引导应用程序，它在AWS EC2实例上运行

可部署的只是一个内嵌了tomcat的jar

我试图让应用程序将其访问日志发送到syslog，以便使用AWS CloudWatch从不同的EC2实例收集日志

我已经尝试过，但由于以下问题，它无法与syslog一起工作：

然后我尝试了CommonRequestLoggingFilter，这似乎并没有将其日志发送到syslog

我想尝试用Spring引导应用程序将日志发送到syslog并不是一个罕见的愿望

有什么综合方法可以做到这一点吗？

我刚刚在我的应用程序中实现了这一点。（适用于弹簧护套1.5.6）

确保您的tomcat访问日志记录处于打开状态，下面是在application.yml中启用访问日志记录的方式-

server: 
 tomcat:
  accesslog:
    enabled: true
    pattern: "<APPNAME> %h %l %u %t \"%r\" %s %b %D"
    prefix: "localhost_access_log"
    suffix: .txt
  basedir: /opt/tomcat 

现在在您的logback xml中进行必要的配置

<!--This will print app logs in user facility-->
<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
 <syslogHost><<your host name>></syslogHost>
 <port>514</port>
 <facility>USER</facility>
 <suffixPattern><<your pattern>></suffixPattern>
</appender>
<!-- This will print your access logs in local0 facility-->
<appender name="LOCAL0" class="ch.qos.logback.classic.net.SyslogAppender">
  <syslogHost><<your host name>></syslogHost>
  <port>514</port>
  <facility>LOCAL0</facility>
  <suffixPattern><<pattern>></suffixPattern>
</appender>

<Logger name="package path to ApiAccessLogValve" level="INFO" 
    additivity="false">
   <appender-ref ref="LOCAL0" />
</Logger>

现在您都准备好了。

        AbstractAccessLogValve accessLogValve = new ApiAccessLogValve();
        accessLogValve.setPattern("common");
        factory.addContextValves(accessLogValve);
     } else {
     logger.error("WARNING! this customizer does not support your
