spring3中使用SLF4J

在SPRING中使用SLF4J进行日志记录,在非WEB的模式下可以通过如下方法进行:

 private static Logger log = LoggerFactory.getLogger(TestSlf4jLog.class);

 public static void main(String[] args) throws Exception {
  String logbackCfg = "resources/logback.xml";
  URL logURL = new ClassPathResource(logbackCfg).getURL();
  ILoggerFactory loggerFactory = LoggerFactory.getILoggerFactory();
  LoggerContext loggerContext = (LoggerContext) loggerFactory;
  JoranConfigurator configurator = new JoranConfigurator();
  configurator.setContext(loggerContext);
  loggerContext.stop();
  configurator.doConfigure(logURL);
  log.debug("debug");
  String str = "this is info";
  log.info("{}", str);
  String str2 = "警告";
  log.warn("这是一个{}", str2);
 }

 

而在WEB模式下,可以通过增加一个LISTENER来实现在WEB.XML中增加如下配置:

 

<context-param>
  <param-name>logbackConfigLocation</param-name>
  <param-value>classpath:resources/logback.xml</param-value>
 </context-param>

 

 

<listener>
  <listener-class>ch.qos.logback.classic.servlet.LogbackConfigListener</listener-class>
 </listener>

 

以上LISTENER的类在附件中可以找到!
