在项目中配置log4j

jiadong — Mon, 12 Nov 2007 04:21:00 GMT

如下：

1.配置Log4j.propertity文件在webroot下（我的目录是：/logconfig/log4j.propertity）

## LOGGER ##
## configure root Logger
log4j.rootLogger=INFO,console,flow,errorfile

## APPENDERS ##
# define an appender named console, which is set to be a ConsoleAppender
log4j.appender.console=org.apache.log4j.ConsoleAppender

# define an appender named file, which is set to be a DailyRollingFileAppender
log4j.appender.flow=org.apache.log4j.DailyRollingFileAppender
log4j.appender.flow.File=${catalina.base}/logs/flowlog/Flowlog.txt
log4j.appender.flow.DatePattern=yyyy-MM-dd'.txt'
log4j.appender.flow.Threshold=INFO
log4j.appender.flow.Append=true

log4j.appender.errorfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.errorfile.File=${catalina.base}/logs/errorlog/errorlog.txt
log4j.appender.errorfile.DatePattern=yyyy-MM-dd'.txt'
log4j.appender.errorfile.Threshold=WARN
log4j.appender.file.Append=true

## LAYOUTS ##
# assign a PatternLayout to console appender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %l %n%-5p:  %m%n

# assign a PatternLayout to file appender
log4j.appender.flow.layout=org.apache.log4j.PatternLayout
log4j.appender.flow.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %l %n%-5p:  %m%n

log4j.appender.errorfile.layout=org.apache.log4j.PatternLayout
log4j.appender.errorfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %l %n%-5p:  %m%n

2.初始化Log4j

package com.bjzc.utility;

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class LogUtil {
    /**
     * 功能：初始化日志
     * @author jiadong
     *
     */
    public static String ConfigPath ;

    /**
     * 初始化日志属性设置
     *
     */
    public static void init(){
        String log4jPath = ConfigPath ;
        PropertyConfigurator.configure(log4jPath);


    }
    /**
     * 流程记录日志获取
     */
    public static Logger getFlowLogger(){
        return Logger.getLogger("flow");
    }
    /**
     * 错误日志获取
     */
    public static Logger getErrorLogger(){
        return Logger.getLogger("error");
    }


}

ackage com.bjzc.utility;

import org.apache.log4j.Logger;
/**
* 功能：后台输出日志
* @author jiadong
*版本：1.0
*时间：2007年11月12日
*/

public class InitLogger {

    public static Logger writeLog ;

    public static void init(){
        InitLogger.writeLog = LogUtil.getFlowLogger() ;
    }
}

3.在项目启动的时候初始化日志配置，写个servlet通过web.xml写入

package com.bjzc.utility;

import javax.servlet.ServletConfig;
import javax.servlet.http.HttpServlet;
/**
* 初始化的Servlet
* @author jiadong
*版本：1.0
*时间：2007年11月09日
*/
@SuppressWarnings("serial")
public class InitServlet extends HttpServlet {

        @SuppressWarnings("unused")
        private ServletConfig config ;

        public void init(ServletConfig config){

            try {
                this.config = config;
                String configPath = config.getServletContext().getRealPath(
                        "/logconfig/log4j.properties");
                LogUtil.ConfigPath = configPath;
                LogUtil.init();
                InitLogger.init();
                InitLogger.writeLog.info("初始化成功！");
            } catch (Exception e) {
                InitLogger.writeLog.info("初始化错误！");
            }

        }
}

4.写入web.xml

<servlet>
  <description>Servlet of init Logdescription>
  <display-name>by jiadongdisplay-name>
  <servlet-name>InitServletservlet-name>
  <servlet-class>com.bjzc.utility.InitServletservlet-class>
  <load-on-startup>1load-on-startup>
  servlet>

<servlet-mapping>
  <servlet-name>InitServletservlet-name>
  <url-pattern>/com/bjzc/utility/InitServleturl-pattern>
  servlet-mapping>

public class HtmlTagsProcessor {

    public static String tagsProcessor(String inputString){

        Pattern js_pattern,style_pattern, html_pattern ,particular_pattern;
        Matcher js_matcher,style_matcher,html_matcher,particular_matcher;

        //过滤js的正则表达式

        //过滤html标签的正则表达式
        String html_str = "<[^>]+>" ;
        String particular_str = ">|&| |"";

        //处理js标签
        js_pattern = Pattern.compile(js_str, Pattern.CASE_INSENSITIVE);
        js_matcher = js_pattern.matcher(inputString);
        processedString = js_matcher.replaceAll("");

        //处理样式标签
        style_pattern = Pattern.compile(style_str, Pattern.CASE_INSENSITIVE);
        style_matcher = style_pattern.matcher(processedString);
        processedString = style_matcher.replaceAll("");

        //处理html标签
        html_pattern = Pattern.compile(html_str, Pattern.CASE_INSENSITIVE);
        html_matcher = html_pattern.matcher(processedString);
        processedString = html_matcher.replaceAll("");

        particular_pattern = Pattern.compile(particular_str,Pattern.CASE_INSENSITIVE);
        particular_matcher = particular_pattern.matcher(processedString);
        processedString = particular_matcher.replaceAll("");
        return processedString ;
    }

}

常用正则表达

jiadong — Wed, 17 Oct 2007 01:57:00 GMT

摘要: 匹配中文字符的正则表达式： [\u4e00-\u9fa5]
评注：匹配中文还真是个头疼的事，有了这个表达式就好办了

匹配双字节字符(包括汉字在内)：[^\x00-\xff]
评注：可以用来计算字符串的长度（一个双字节字符长度计2，ASCII字符计1）

匹配空白行的正则表达式：\n\s*\r
评注：可以用来删除空白行

如何使用单元测试Junit

jiadong — Mon, 27 Aug 2007 02:28:00 GMT

其实做单元测试很简单，只需要自己编写一个类，该类从junit.framework.TestCase派生而来

写自己的一个方法，运行该方法就ok了！
例如：要对上次所编写的多对多做单元测试，可以编写如下的类Test.java

1package org.jia;
2
3import java.util.HashSet;
4
5import junit.framework.TestCase;
6
7public class Test extends TestCase{
8
9    @SuppressWarnings("unchecked")
10    public void test(){
11        Student student1 = new Student("jiadong1",new HashSet());
12        Student student2 = new Student("jiadong2",new HashSet());
13        Teacher teacher1 = new Teacher("teacher1",new HashSet());
14        Teacher teacher2 = new Teacher("teacher2",new HashSet());
15        teacher1.getstudents().add(student1);
16        teacher2.getstudents().add(student2);
17        teacher2.getstudents().add(student1);
18        teacher1.getstudents().add(student2);
19        Operator o = new Operator();
20        o.save(teacher1);
21        o.save(teacher2);
22    }
23
24    @Override
25    protected void setUp() throws Exception {
26        // TODO Auto-generated method stub
27        super.setUp();
28        System.out.println("start--------------");
29    }
30
31    @Override
32    protected void tearDown() throws Exception {
33        // TODO Auto-generated method stub
34        super.tearDown();
35        System.out.println("end............................");
36    }
37}
38

如果运行完为绿色，则说明单元测试通过
如果是红色，说明程序中有问题，可以通过他提示的异常，找出程序中的错误，调试直到通过
