这里在网上找了几个模块,学习完前面几个博客后我已经能看懂了,以后项目中用到,根据需求改动就ok了,免得再百度。

复杂点的:
<?xml version="1.0" encoding="UTF-8"?> <!-- 说明: 1、日志级别及文件 日志记录采用分级记录,级别与日志文件名相对应,不同级别的日志信息记录到不同的日志文件中 例如:error级别记录到log_error_xxx.log或log_error.log(该文件为当前记录的日志文件),而log_error_xxx.log为归档日志, 日志文件按日期记录,同一天内,若日志文件大小等于或大于2M,则按0、1、2...顺序分别命名 例如log-level-2013-12-21.0.log 其它级别的日志也是如此。 2、文件路径 若开发、测试用,在Eclipse中运行项目,则到Eclipse的安装路径查找logs文件夹,以相对路径../logs。 若部署到Tomcat下,则在Tomcat下的logs文件中 3、Appender FILEERROR对应error级别,文件名以log-error-xxx.log形式命名 FILEWARN对应warn级别,文件名以log-warn-xxx.log形式命名 FILEINFO对应info级别,文件名以log-info-xxx.log形式命名 FILEDEBUG对应debug级别,文件名以log-debug-xxx.log形式命名 stdout将日志信息输出到控制上,为方便开发测试使用 --> <configuration> <!-- 在Eclipse中运行,请到Eclipse的安装目录中找log文件,Tomcat下,请到Tomcat目录下找 --> <!-- <property name="LOG_PATH" value="/xebest/logs/llmj-app" /> --> <property name="LOG_PATH" value="E:/logs/llmj-app" /> <!-- 日志记录器,日期滚动记录 --> <appender name="FILEERROR" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 正在记录的日志文件的路径及文件名 --> <file>${LOG_PATH}/log_error.log</file> <!-- 日志记录器的滚动策略,按日期,按大小记录 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 归档的日志文件的路径,例如今天是2013-12-21日志,当前写的日志文件路径为file节点指定,可以将此文件与file指定文件路径设置为不同路径,从而将当前日志文件或归档日志文件置不同的目录。 而2013-12-21的日志文件在由fileNamePattern指定。%d{yyyy-MM-dd}指定日期格式,%i指定索引 --> <fileNamePattern>${LOG_PATH}/log-error-%d{yyyy-MM-dd}.%i.log </fileNamePattern> <!-- 除按日志记录之外,还配置了日志文件不能超过2M,若超过2M,日志文件会以索引0开始, 命名日志文件,例如log-error-2013-12-21.0.log --> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>2MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <!-- 追加方式记录日志 --> <append>true</append> <!-- 日志文件的格式 --> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>%-5p [%d][%mdc{mdc_userId}] %C:%L -
