logback日志文件需要注意点

1.支持的jar包

logback-access-1.1.1.jar
logback-classic-1.1.1.jar
logback-core-1.1.1.jar

2.logback.xml文件,web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">  

    <!--日志路径 -->
    <property name="LOG_HOME" value="/dd/log" />

    <!-- 日志文件输出  -->
    <appender name="rollingFileOut" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <Encoding>UTF-8</Encoding>
        <prudent>true</prudent>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_HOME}/autoCon-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxHistory>30</maxHistory>
            <timeBasedFileNamingAndTriggeringPolicy  class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy><!--  -->
            <!-- <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
                 <MaxFileSize>0.1MB</MaxFileSize>
            </triggeringPolicy> -->

        </rollingPolicy>
        <encoder>
            <pattern>%date %level [%thread] %logger.%class{0}#%method [%file:%line] %msg%n</pattern>
            <charset>GBK</charset>
        </encoder>
    </appender>  

    <!--定义控制台输出 -->
    <appender name="consoleOut" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%date %level [%thread] %logger.%class{0}#%method [%file:%line] %msg%n</pattern>
        </encoder>
    </appender>  

    <logger name="App">
        <appender-ref ref="rollingFileOut" />
    </logger> 

    <!-- <root level="debug">
        <appender-ref ref="consoleOut" />
        <appender-ref ref="rollingFileOut" />
    </root>  -->
    <root level="debug">
        <appender-ref ref="consoleOut" />
        <appender-ref ref="rollingFileOut" />
    </root> 

</configuration>  

<listener>
        <listener-class>com.autoyolConsole.util.listener.LogbackConfigListener</listener-class>
    </listener>
    <context-param>
        <param-name>logbackConfigLocation</param-name>
        <param-value>classpath:conf/logback.xml</param-value>
    </context-param>

3.需要注意点

logback.xml 里把这部分 <appender-ref ref="consoleOut" /> 注释掉就可以了
catalina.out 就相当于tomcat的控制台的输出
