如何以编程方式告诉 Logback 1.4.x 重新加载配置?
我找到了重新加载 logback 1.2.x 配置的答案,但它不适用于 logback 1.4.x(也不是 1.3.x),因为它给出了编译错误:
The method findURLOfDefaultConfigurationFile(boolean) is undefined for the type ContextInitializer
在Logback 1.4.x中,
findURLOfDefaultConfigurationFile(boolean)
方法确实不可用。相反,Logback 1.4.x 引入了一种使用 LoggerContext 类以编程方式重新加载其配置的新方法。要以编程方式触发配置重新加载,您可以使用以下方法:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.core.joran.spi.JoranException;
public class LogbackConfigReload {
public static void main(String[] args) {
// Get the LoggerContext
LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
try {
// Create a JoranConfigurator
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(loggerContext);
loggerContext.reset();
// Reload the configuration from the default configuration file
configurator.doConfigure("logback.xml"); // Replace with the path to your configuration file
// Log a message to verify that the configuration was reloaded
Logger logger = LoggerFactory.getLogger(LogbackConfigReload.class);
logger.info("Configuration reloaded successfully");
} catch (JoranException e) {
// Handle the exception if the configuration reload fails
e.printStackTrace();
}
}
}
在此代码中:
最后,我记录一条消息,表明配置已重新加载。
