1實現.控制臺輸出

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><target>System.out</target><encoder><Pattern> %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36}-%msg%n </Pattern><charset>utf-8</charset></encoder><filter class="ch.qos.logback.classic.filter.LevelFilter"><level>error</level><onMatch>DENY</onMatch><onMismatch>ACCEPT</onMismatch></filter> </appender> <appender name="STDOUT_ERROR" class="ch.qos.logback.core.ConsoleAppender"><target>System.err</target><encoder><Pattern> %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} -%msg%n </Pattern><charset>utf-8</charset></encoder><filter class="ch.qos.logback.classic.filter.LevelFilter"><level>error</level><onMatch>ACCEPT</onMatch><onMismatch>DENY</onMismatch></filter> </appender>

2實現：將所有的日志消息一直追加到指定的文件中

<appender name="FILE_APPEND" class="ch.qos.logback.core.FileAppender"><file>F:/log/test/logback.log</file><encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"><Pattern> %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} -%msg%n </Pattern><charset>utf-8</charset></encoder><append>true</append> </appender>

3實現:每天產生一個日志文件且只保存最近10天的日志

<appender name="FILE_LIMITED_ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender"><file>F:/log/test/today.log</file><encoder><pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level [%thread] %logger{36} - %msg%n</pattern><charset>utf-8</charset></encoder><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><fileNamePattern>F:/log/test/%d{yyyy-MM-dd}.log</fileNamePattern><!-- 10 day --><maxHistory>10</maxHistory></rollingPolicy> </appender>

?4實現.一天產生一個日志，如果當天日志超過10M將進行再分割

<appender name="FILE_DAILY_ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender"><file>F:/log/test/today.log</file><encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"><Pattern> %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n </Pattern><charset>utf-8</charset></encoder><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!-- rollover daily --><fileNamePattern>F:/log/test/%d.%i.log</fileNamePattern><timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"><maxFileSize>10MB</maxFileSize></timeBasedFileNamingAndTriggeringPolicy></rollingPolicy> </appender>

5實現：所有的日志消息追加到一個日志文件中，如果該文件超過100M,就將其打包成zip.（歸檔個數不限）
?注意：*fileNamePattern不能使用%d，
? ? ? ? ? *如果歸檔文件名為backup%i.zip，那么日志文件的后綴名(log)將丟失

<appender name="FILE_ARCHIVE" class="ch.qos.logback.core.rolling.RollingFileAppender">?<file>F:/log/test/logback.log</file>?<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">?<fileNamePattern>F:/log/test/backup%i.log.zip</fileNamePattern> ????</rollingPolicy>?<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">?<maxFileSize>100MB</maxFileSize> ????</triggeringPolicy>?<encoder>?<pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %level %logger{36} - %msg%n</pattern> ????</encoder> </appender>

6實現: 【在5實的基礎上添加】只保存最近的3個歸檔文件（.zip）

<appender name="FILE_LIMITED_ARCHIVE" class="ch.qos.logback.core.rolling.RollingFileAppender">?<file>F:/log/test/logback.log</file>?<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">?<fileNamePattern>F:/log/test/backup%i.log.zip</fileNamePattern>?<minIndex>1</minIndex>?<maxIndex>3</maxIndex> ????</rollingPolicy>?<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">?<maxFileSize>100MB</maxFileSize> ????</triggeringPolicy>?<encoder>?<pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %level %logger{36} - %msg%n</pattern> ????</encoder> </appender>

7.輸出到數據庫

<!--日志異步到數據庫 --> <appender name="DBAppender" class="ch.qos.logback.classic.db.DBAppender"><connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"><dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"><driverClass>com.mysql.jdbc.Driver</driverClass><jdbcUrl>jdbc:mysql://xxxx:3306/xy-pay?autoReconnect=true&amp;failOverReadOnly=false&amp;maxReconnects=10&amp;allowMultiQueries=true</jdbcUrl><user>xxx</user><password>xxx</password></dataSource></connectionSource><filter class="ch.qos.logback.classic.filter.LevelFilter"><level>error</level><onMatch>ACCEPT</onMatch><onMismatch>DENY</onMismatch></filter></appender>建表如下：BEGIN; DROP TABLE IF EXISTS logging_event_property; DROP TABLE IF EXISTS logging_event_exception; DROP TABLE IF EXISTS logging_event; COMMIT; BEGIN; CREATE TABLE logging_event ( timestmp BIGINT NOT NULL, formatted_message TEXT NOT NULL, logger_name VARCHAR(254) NOT NULL, level_string VARCHAR(254) NOT NULL, thread_name VARCHAR(254), reference_flag SMALLINT, arg0 VARCHAR(254), arg1 VARCHAR(254), arg2 VARCHAR(254), arg3 VARCHAR(254), caller_filename VARCHAR(254) NOT NULL, caller_class VARCHAR(254) NOT NULL, caller_method VARCHAR(254) NOT NULL, caller_line CHAR(4) NOT NULL, event_id BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY ); COMMIT; BEGIN; CREATE TABLE logging_event_property ( event_id BIGINT NOT NULL, mapped_key VARCHAR(254) NOT NULL, mapped_value TEXT, PRIMARY KEY(event_id, mapped_key), FOREIGN KEY (event_id) REFERENCES logging_event(event_id) ); COMMIT; BEGIN; CREATE TABLE logging_event_exception ( event_id BIGINT NOT NULL, i SMALLINT NOT NULL, trace_line VARCHAR(254) NOT NULL, PRIMARY KEY(event_id, i), FOREIGN KEY (event_id) REFERENCES logging_event(event_id) ); COMMIT;
