logback 生成日誌

（1）第一種配置以下時，將會使日誌文件日後累加，而不是每日只生成當日的日誌文件

<appender name="logfile"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<File>../ptvslog/access.log</File>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

<!-- keep 1 days worth of history -->

<MaxHistory>1</MaxHistory>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

（2）第二種配置以下時，按天生成日誌文件，天天的日誌文件裏只保存當天的日誌信息

<appender name="logfile2"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<Prudent>true</Prudent>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

<!-- keep 60 days worth of history -->

<MaxHistory>60</MaxHistory>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

（2）第三種配置以下時，按天生成文件夾，每一個文件夾裏放當天的日誌文件

<appender name="logDirfile"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<Prudent>true</Prudent>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/%d{yyyy-MM-dd}/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

如下配置表示DataController類的INFO日誌以logDirfile輸出，additivity="false"表示只在

logDirfile輸出，不在其餘輸出臺輸出，若是設置爲true，表示要在其餘地方也輸出。

<logger name="com.apabi.ptvs.web.DataController"

additivity="false">

<level value="INFO" />

<appender-ref ref="logDirfile" />

</logger>

<root level="INFO">

<appender-ref ref="stdout" />

<appender-ref ref="R" />

</root>

</configuration>
