customeractionservlet.java

j2EE开发 关于使用log4j的一个示例 里面还有PPT文档说明

package logextendActionServlet;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.struts.action.ActionServlet;

public class CustomerActionServlet extends ActionServlet {

	@Override
	public void init() throws ServletException {
		// TODO 自动生成方法存根
		super.init();
		ServletContext context = getServletContext();
		String path =context.getRealPath("/") + "/" + getInitParameter("log4j");
		System.out.println(path);
		PropertyConfigurator.configure(path);
		Logger rootLogger = Logger.getRootLogger();
		Logger myLogger = Logger.getLogger("myLogger");
	 	context.setAttribute("rootLogger", rootLogger);
	 	context.setAttribute("myLogger", myLogger);
	}

}
