Tomcat/conf下logging.properties

在Tomcat根目录conf文件夹下会有一个logging.properties文件，主要负责输出tomcat自身的日志文件。

Tomcat使用的日志配置文件：$CATALINA_BASE/conf/logging.properties

【1】logging.properties一般如下：

可以看到，tomcat自身的日志都生成在了./logs/文件夹内。

【2】Tomcat默认使用JULI日志系统，其日志信息分为两类：

·
① 运行中的日志，它主要记录运行的一些信息，尤其是一些异常错误日志信息 。

② 访问日志信息，它记录的访问的时间，IP ，访问的资料等相关信息。

【3】Catalina引擎的日志文件，文件名catalina.日期.log

---

【4】Tomcat下内部代码抛出的日志，文件名localhost.日期.log

jsp页面内部错误的异常，org.apache.jasper.runtime.HttpJspBase.service类抛出的，日志信息就在该文件！

---

【5】Tomcat下默认manager应用日志，文件名manager.日期.log

控制台输出的日志，Linux下默认重定向到catalina.out。

以上属于第一种–运行日志。

---

【6】Access日志

默认 tomcat 不记录访问日志，如下方法可以使 tomcat 记录访问日志

编辑 ${catalina}/conf/server.xml 文件;注 :${catalina} 是 tomcat 的安装目录

在${catalina}/conf/server.xml文件中可以看到访问日志配置：

 <!-- Access log processes all example.             Documentation at: /docs/config/valve.html             Note: The pattern used is equivalent to using pattern="common" -->        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log." suffix=".txt"/>

访问日志如下图：

日志内容如下图所示：

【7】日志类型与级别

Tomcat 日志分为下面５类：

catalina 、 localhost 、 manager 、 localhost_access、 host-manager

每类日志的级别分为如下 7 种：

SEVERE (highest value) > WARNING > INFO > CONFIG > FINE > FINER > FINEST (lowest value)

日志级别的设定方法

修改 conf/logging.properties 中的内容，设定某类日志的级别

示例：

设置 catalina 日志的级别为： FINE

catalina.org.apache.juli.FileHandler.level = FINE

禁用 catalina 日志的输出：

catalina.org.apache.juli.FileHandler.level = OFF

输出 catalina 所有的日志消息均输出：

catalina.org.apache.juli.FileHandler.level = ALL
