java - Tomcat 日志记录问题

Question

我已将控制台配置为显示更精细的消息，但只显示严重消息和信息消息。 fine, config, finer 等其他消息无法显示。

有人可以提供帮助吗？

输出

29-Aug-2018 18:55:34.918 INFO [http-nio-7080-exec-1] org.apache.jsp.a_jsp._jspService INFO...
29-Aug-2018 18:55:34.922 SEVERE [http-nio-7080-exec-1] org.apache.jsp.a_jsp._jspService SEVERE

JSP

<%! org.slf4j.Logger log = org.slf4j.LoggerFactory.getLogger("JSPname"); 
    java.util.logging.Logger LOG = java.util.logging.Logger.getLogger("simple logger");
%>

<% log.info("Hello Logging!"); %>

<%
LOG.log(java.util.logging.Level.INFO, "INFO...");

只看到 INFO 和 SEVERE 是正常的。

https://tomcat.apache.org/tomcat-7.0-doc/logging.html

摘录:

It can be noted, though, that in Apache Tomcat implementation the calls to ServletContext.log(String) or GenericServlet.log(String) are logged at the INFO level. The calls to ServletContext.log(String, Throwable) or GenericServlet.log(String, Throwable) are logged at the SEVERE level.

老实说，你应该尝试使用像 log4j 这样的外部 API。
