Tomcat 9 打印 http header

一、tomcat 设置 Request_Dumper_Filter ，打印 hearder

https://tomcat.apache.org/tomcat-9.0-doc/config/filter.html#Request_Dumper_Filter

修改 CATALINA_BASE/conf/web.xml，在 <web-app> </web-app> 之间添加Request Dumper Filter，如下

<web-app>
...
  <!-- == Request Dumper Filter  == -->
    <filter>
        <filter-name>requestdumper</filter-name>
        <filter-class>
            org.apache.catalina.filters.RequestDumperFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>requestdumper</filter-name>
        <url-pattern>*</url-pattern>
    </filter-mapping>

</web-app>

日志输出在 catalina.out，如下：

二、设置打印到独立的日志文件

修改 CATALINA_BASE/conf/logging.properties，创建日志文件

############################################################
# Request Dumper Filter, extral log
############################################################
# To this configuration below, 1request-dumper.org.apache.juli.FileHandler
# also needs to be added to the handlers property near the top of the file
1request-dumper.org.apache.juli.FileHandler.level = INFO
1request-dumper.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1request-dumper.org.apache.juli.FileHandler.prefix = request-dumper.
1request-dumper.org.apache.juli.FileHandler.encoding = UTF-8
1request-dumper.org.apache.juli.FileHandler.formatter = org.apache.juli.VerbatimFormatter
org.apache.catalina.filters.RequestDumperFilter.level = INFO
org.apache.catalina.filters.RequestDumperFilter.handlers = \
  1request-dumper.org.apache.juli.FileHandler

注意
要把 1request-dumper.org.apache.juli.FileHandler 添加到文件上部的 handlers。
如下：
handlers = 1catalina.org.apache.juli.AsyncFileHandler, 2localhost.org.apache.juli.AsyncFileHandler, 3manager.org.apache.juli.AsyncFileHandler, 4host-manager.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler, 1request-dumper.org.apache.juli.FileHandler

然后，就出现了独立的日志文件
