项目启动时增加日志与系统配置

在web.xml中增加Servlet：log4j

<servlet> <servlet-name>log4j</servlet-name> <servlet-class>com.wafer.weixin.servlet.Log4JServlet</servlet-class> <load-on-startup>1</load-on-startup>//加载该servlet，1代表优先级 </servlet> <servlet-mapping> <servlet-name>log4j</servlet-name> <url-pattern>/log4j</url-pattern></servlet-mapping>

Log4JServlet：

package com.wafer.weixin.servlet; import java.text.SimpleDateFormat;import java.util.Date; import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import java.io.BufferedInputStream;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import java.util.Properties;import org.apache.log4j.PropertyConfigurator; import com.wafer.weixin.util.MessageUtil;import com.wafer.weixin.util.SignUtil;import com.wafer.weixin.util.WeixinUtil; public class Log4JServlet extends HttpServlet{

//增加日志

public static org.apache.log4j.Logger log=org.apache.log4j.Logger.getLogger(Log4JServlet.class.getName()); public void init() throws ServletException{ Date d=new Date();SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String date=df.format(d); log.info("开始加载日志配置...."); String path = getServletContext().getRealPath("/"); String filename = path+"WEB-INF\\log4j.properties"; PropertyConfigurator.configure(filename); log.info("日志配置加载完成...."); log.info("日志配置地址："+filename);

//增加系统配置

String name="config\\system_config.propertys"; InputStream in;try {Properties p = new Properties();in = new BufferedInputStream(new FileInputStream(path+name)); log.info("系统配置路径1："+path+name);p.load(in);SignUtil.token=p.getProperty("token");WeixinUtil.appId=p.getProperty("appId");WeixinUtil.appSecret=p.getProperty("appSecret");MessageUtil.cache=p.getProperty("cache");MessageUtil.INTER_FACE_HOST=p.getProperty("INTER_FACE_HOST");MessageUtil.WEIXIN_HOST=p.getProperty("WEIXIN_HOST");MessageUtil.toUserName=p.getProperty("toUserName");log.info(SignUtil.token);log.info(WeixinUtil.appId);log.info(WeixinUtil.appSecret);log.info(MessageUtil.cache);log.info(MessageUtil.INTER_FACE_HOST);log.info(MessageUtil.WEIXIN_HOST);log.info(MessageUtil.toUserName);} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} }}

system_config.propertys：
