log4j在jsp中如何使用

Question

log4j在java编程时测试都没有问题,但是在jsp编程时提示

 log4j:WARN No appenders could be found for logger (ssm.servlet.UserServlet).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

在jsp编程时是不是需要写一个servlet用来获取log4j文件?我这个是没有写这个servlet的,就单纯在servlet中调用logger

 private void doReg(HttpServletRequest request, HttpServletResponse response) {
        // TODO Auto-generated method stub
        Logger logger=Logger.getLogger(UserServlet.class);
        logger.debug("doReg work");
    }

另外请问在jsp编程时使用log4j的流程是什么?

Answer 1

你这个是没有找到log4j的配置路径
