使用logback進行日誌的打印

resources下面編輯logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
      <encoder charset="UTF-8">
         <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] %5p %m%n</pattern>
      </encoder>
   </appender>

   <!-- 出錯日誌 appender  -->
   <appender name="ERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
      <file>./logs/LinkManagerAPP_logs/error/LinkManagerAPP_error_console.log</file>
      <append>true</append>
      <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
         <!-- 按天回滾 daily -->
         <!-- log.dir 在maven profile裏配置 -->
         <fileNamePattern>./logs/LinkManagerAPP_logs/error/LinkManagerAPP_error_console-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
         <!-- 日誌最大的歷史 2天 -->
         <maxHistory>2</maxHistory>
         <timeBasedFileNamingAndTriggeringPolicy
               class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10485760</maxFileSize>
         </timeBasedFileNamingAndTriggeringPolicy>
      </rollingPolicy>
      <encoder>
         <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
         <charset class="java.nio.charset.Charset">UTF-8</charset>
      </encoder>
      <filter class="ch.qos.logback.classic.filter.LevelFilter"><!-- 只打印錯誤日誌 -->

   <root  level="DEBUG">

</configuration>

代碼中使用樣例：

public static final Logger LOGGER = LoggerFactory.getLogger(SequenceProducer.class);
