logback |
------------------------
# log4j作者的又一个力作
# logback当前分成三个模块：
logback-core
logback- classic
logback-access
* logback-core是其它两个模块的基础模块。
* logback-classic是log4j的一个 改良版本。
* logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。
* logback-access访问模块与Servlet容器集成提供通过Http来访问日志的功能。
# maven 依赖

logback - 配置详解 |
------------------------
logback.xml 配置
<configuration>
<property name="LEVEL" value="DEBUG"/>
<property name="PATTERN-A" value="%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"/>
<property name="PATTERN-B" value="[%-5p][%thread][%d{yyy-MM-dd HH:mm:ss}][%C %M] ==> : %m%n"/>
<appender name="ROOT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>${PATTERN-A}</pattern>
<charset>UTF-8</charset>
</encoder>
<target>System.out</target>
</appender>
<root level="${LEVEL}">
<appender-ref ref="ROOT"/>
</root>
</configuration>
appender :通过 class 来确定当前appender是输出到控制台还是输出到文件夹,还是滚动,不同的 class 会有不同的子标签来控制属性
root :可以添加一个或者多个 appender
web.xml 配置
<listener>
<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
</listener>
<context-param>
<param-name>logbackConfigLocation</param-name>
<param-value>classpath:logback.xml</param-value>
</context-param>
