通过URL方式动态修改logback level级别

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.LoggerContext;
public class LogLeveLController{

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

    public void control(HttpServletRequest req) {
        String logLevel = req.getParameter("logLevel");
        try {
            LoggerContext logcontext = (LoggerContext) LoggerFactory.getILoggerFactory();
            logcontext.getLogger("org.mybatis").setLevel(Level.valueOf(logLevel));
            logcontext.getLogger("org.springframework").setLevel(Level.valueOf(logLevel));
            logcontext.getLogger("org.quartz").setLevel(Level.valueOf(logLevel));
        } catch (Exception e) {
            log.error("动态修改日志级别出错", e);
        }
   }
}

该种实现方式主要是为了应对在生产环境动态查看logback日志级别，一般生产环境中的level为info级别，可能查看问题时可修改为debug级别，当然也可使用界面设置切换级别的模式
