logback加載非類路徑下的logback配置文件並設置定時更新

定時重新加載logback配置文件

logback.xml

<configuration  scan="true" scanPeriod="30 seconds">   ....   </configuration>

配置說明：
- scan: 設置為true,代表會在指定的時間內重新加載日誌配置文件
- scanPeriod:當scan=true時，日誌配置文件會在指定的單位時間內重新加載，默認是每分鐘會重載一次。
- scanPeriod的配置說明:
時間單位：milliseconds, seconds, minutes , hours

eg:

5分鐘： <configuration  scan="true" scanPeriod
 
="5 minutes"> 1小時:  <configuration  scan="true" scanPeriod="1 hours">

加載非類路徑下的logback.xml配置文件

主方法中調用如下代碼:

//logback.xml的路徑名 File file = new File(System.getProperty("user.dir") + "/conf/logback.xml"); LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); JoranConfigurator joranConfigurator = new
 
 JoranConfigurator(); joranConfigurator.setContext(loggerContext); loggerContext.reset(); try {     joranConfigurator.doConfigure(file); } catch (Exception e) {     System.out.println(String.format("Load logback config file error. Message: ", e.getMessage())); } StatusPrinter.printInCaseOfErrorsOrWarnings(loggerContext);

剝離代碼為一個類:

 import ch.qos.logback.classic.LoggerContext; import ch.qos.logback.classic.joran.JoranConfigurator; import ch.qos.logback.core.util.StatusPrinter; import org.slf4j.LoggerFactory;  import java.io.File;  /**  * Created by xuyh at 2017/11/20 14:32.  */ public class LogbackInit {     /**      * 設置logback.xml配置文件並加載      *      * @param configFilepathName 配置文件路徑名      */     public static void initLogback(String configFilepathName) {         File file = new File(configFilepathName);         LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();         JoranConfigurator joranConfigurator = new JoranConfigurator();         joranConfigurator.setContext(loggerContext);         loggerContext.reset();         try {             joranConfigurator.doConfigure(file);         } catch (Exception e) {             System.out.println(String.format("Load logback config file error. Message: ", e.getMessage()));         }         StatusPrinter.printInCaseOfErrorsOrWarnings(loggerContext);     } }
