Read the log4j configuration file outside the jar package

Read the log4j configuration file outside the jar package

Background: Put all the configuration files out, and I deleted all the configuration files in the jar package. Need to read the configuration file in the same directory of the jar package.

1. The xml file does not seem to be configured and can be read directly.
2. The log4j configuration file needs to add the following statement in the main function (I added the first line under the main function)

PropertyConfigurator.configure(System.getProperty("user.dir") + "/log4j.properties");

Note: My properties file is read from the src directory by default. If it
seems to be placed in the secondary or tertiary directory, "/log4j.properties" The configuration here needs to be changed. I didn't use it so I didn't try it.

3. How to read the ini file

ublic Hashtable getConfigFile(){
    
    
		Hashtable htable = new Hashtable();
		System.out.println("获取dbconfig.ini配置参数");
		FileReader fr = null;
		BufferedReader br = null;
		//String Config_dir = this.getClass().getResource("dbconfig.ini").getPath();
		try {
    
    
			fr = new FileReader(new File(FinalParam.Config_dir));
			//fr = new FileReader(new File(Config_dir));
			br = new BufferedReader(fr);
			String tmp_str = null;
			while((tmp_str = br.readLine()) != null){
    
    
				String[] cube_cfg = new String[2];
				if(tmp_str.indexOf("=") != -1){
    
    
					cube_cfg = DoSplitStr(tmp_str);
					htable.put(cube_cfg[0], cube_cfg[1]);
				}else{
    
    
					FinalParam.println("配置文件出现空行，跳过!");
				}
			}
			System.out.println("读取到配置文件配置个数："+htable.size());
		} catch (Exception e) {
    
    
			// TODO Auto-generated catch block
			FinalParam.println("读取配置文件出错!");
			e.printStackTrace();
		}

		return htable;
	}

//在这个函数中实现的调用
    public Connection initConfig2(Connection conn) {
    
    
        System.out.println("初始化数据库链接");
        htable = dofile.getConfigFile();// 读取配置文件，初始化
        conn = dbconn.getConnection(htable);// 获取全局数据库链接
        System.out.println("获取全局数据库链接");
        //System.out.println("conn："+conn.toString());
        if (htable == null || htable.isEmpty() || conn == null) {
    
    
            System.out.println("htable参数为空 或者 初始化连接为null");
        }
        return conn;
    }
