customerlogplugin.java

j2EE开发 关于使用log4j的一个示例 里面还有PPT文档说明

package logPlugIn;

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

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.action.PlugIn;
import org.apache.struts.config.ModuleConfig;

public final class CustomerLogPlugIn implements PlugIn {

	private String pathname;
	
	public String getPathname() {
		return pathname;
	}

	public void setPathname(String pathname) {
		this.pathname = pathname;
	}

	public void destroy() {
		// TODO 自动生成方法存根

	}

	public void init(ActionServlet servlet, ModuleConfig config)
			throws ServletException {
		String path = servlet.getServletContext().getRealPath("/")+"/"+pathname;
		PropertyConfigurator.configure(path);
		Logger rootLogger = Logger.getRootLogger();
		Logger myLogger = Logger.getLogger("myLogger");
	 	ServletContext context = servlet.getServletContext();
	 	context.setAttribute("rootLogger", rootLogger);
	 	context.setAttribute("myLogger", myLogger);
	}

}
