我正在尝试在 Tomcat 7 中记录所有请求/响应的标头。我尝试使用 access-log-valve。但是正如链接中提到的，我们只能一个一个地打印标题。我们必须指定我们需要的每个标题。
例如
pattern="%{User-Agent}i %{Content-Type}i %{Accept}i %{Accept-Encoding}i
%{Accept-Language}i %{Accept-Charset}i %r %h %q"
有没有办法一次记录所有标头，可能是使用通配符？
谢谢。
【问题讨论】：
没有开箱即用的方法 - 但一个简单的替代方法是运行过滤器。过滤器将您想要的所有标头推送到 servlet 请求中。然后在您的模式中使用“%{foo}r”，其中 foo 是 servlet 请求中变量的名称。

David Lee 表示将此添加到您的server.xml：
<Valve className="org.apache.catalina.valves.RequestDumperValve"/>
【讨论】：
初始重要提示，尤其适用于生产环境：小心启用过滤器，因为它可能会损害您的请求参数编码！因此，请务必先设置org.apache.catalina.filters.SetCharacterEncodingFilter，以确保一切正常！
从 Tomcat 7+ 开始，您应该通过 filters 进行操作：
web.xml
<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>
然后记录它，例如到 CATALINA_BASE/conf/logging.properties 中的一些特殊日志文件（基于 Tomcat 7 docs 修改）：
## this may likely be your (to-be-updated) orig handlers declaration:
#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
## ... and you have to add your 1request-dumper:
handlers = \
1request-dumper.org.apache.juli.FileHandler\
,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
## ...
# 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 = localhost_access_log.req-dumps.
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
直到 Tomcat 6 和之前，您都可以使用 RequestDumperValve（如 Brian's answer）：
将此添加到您的 server.xml：
<Valve className="org.apache.catalina.valves.RequestDumperValve"/>
【讨论】：
将此添加到您的 web.xml：
<filter>
<filter-name>Request Dumper Filter</filter-name>
<filter-class>org.apache.catalina.filters.RequestDumperFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Request Dumper Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
这将在 cataline.out 日志文件中记录请求和响应标头：
