log4j1 插入mysql

做任务需要用到这样的需求：

1. 使用log4j 1.2进行日志管理。
2. 将日志输出到mysql中
3. 系统数据库表利用脚本每日生成一张，插入系统运行时特定的表中。

实现方法

1. properties(放在项目根目录中)

    log4j.rootLogger=info, ServerDailyRollingFile, stdout ,logDB
    #这一个为文件输出，并且Daily
    log4j.appender.ServerDailyRollingFile=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd
    log4j.appender.ServerDailyRollingFile.File=D://logs/notify-subscription.log
    log4j.appender.ServerDailyRollingFile.layout=org.apache.log4j.PatternLayout
    log4j.appender.ServerDailyRollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c] %m%n
    log4j.appender.ServerDailyRollingFile.Append=true
    #这一个是配置console输出
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p [%c] %m%n
    #这一个为配置mysql
    log4j.appender.logDB = org.apache.log4j.jdbc.JDBCAppender
    log4j.appender.logDB.layout = org.apache.log4j.PatternLayout
    log4j.appender.logDB.Driver = com.mysql.jdbc.Driver
    log4j.appender.logDB.URL = jdbc:mysql://127.0.0.1:3306/imooc
    log4j.appender.logDB.User = root
    log4j.appender.logDB.Password = root
    log4j.appender.logDB.Sql = INSERT INTO T_log4j(project_name,create_date,level,category,file_name,thread_name,line,all_category,message)values('Struts2','%d{yyyy-MM- ddHH:mm:ss}','%p','%c','%F','%t','%L','%l','%m')

1. 代码（其中要进行修改log4j.appender.logDB.Sql的配置值）

	static Logger log = Logger.getLogger(Main.class);

	public static void main(String[] args) throws FileNotFoundException,
			IOException {

		String dailySqlString = "INSERT INTO T_log4j_"
				+ GetNowDate()
				+ "(project_name,create_date,level,category,file_name,thread_name,line,all_category,message)"
				+ "values('Struts2','%d{yyyy-MM-ddHH:mm:ss}','%p','%c','%F','%t','%L','%l','%m')";

		Properties properties = new Properties();
		properties.load(new FileInputStream("log4j.properties"));
		properties.setProperty("log4j.appender.logDB.Sql", dailySqlString);

		PropertyConfigurator.configure(properties);
                //以下为测试
		try {
			double a = 1 / 0;
		} catch (Exception e) {
			log.error(e);
		}
        }
	//其中GetNowDate用来获取当前时间：
	public static String GetNowDate() {
		String temp_str = "";
		Date dt = new Date();
		SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
		temp_str = sdf.format(dt);
		return temp_str;
	}

3.结果
