回忆:日志文件的重写

 

哎...纯粹就是找点代码做

import org.apache.log4j.Level;
import org.apache.log4j.Logger;

public class SysLogger {
	//	static{
	//	PropertyConfigurator.configure("./config/log4j.properties");
	//}
	private static final String module = SysLogger.class.getName();

	public static void debug(String debugStr) {
		Logger log = Logger.getLogger("debug");
		log.log(module, Level.DEBUG, debugStr, null);
	}

	public static void info(String infoStr) {
		Logger log = Logger.getLogger("info");
		log.log(module, Level.INFO, infoStr, null);
	}

	public static void warn(String warnStr) {
		Logger log = Logger.getLogger("warn");
		log.log(module, Level.WARN, warnStr, null);
	}

	public static void error(String errStr, Throwable e) {
		Logger log = Logger.getLogger("error");
		log.log(module, Level.ERROR, errStr, e);
	}

	public static void error(String errStr) {
		Logger log = Logger.getLogger("error");
		log.log(module, Level.ERROR, errStr, null);
	}

  

接着是读取 配置文件(load 一个输入流就好了)

	InputStream in = *.getResourceAsStream("mongodb.properties");
	Properties prop = new Properties(); 
	prop.load(in);
			
	String host = prop.getProperty("host").trim();
