加载非类路径下的logback.xml配置文件

主方法中调用如下代码:

//logback.xml的路径名 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);

剥离代码为一个类:

 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 {     /**      * 设置logback.xml配置文件并加载      *      * @param configFilepathName 配置文件路径名      */     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);     } }
