LOG4J2使用多個配置文件使用java

可以使用log4j2多個配置文件。我想運行我的項目並加載一個默認配置文件--logger.xml，之後檢查是否有來自另一個文件logger_1.xml的第二個配置，並添加它並且不覆蓋第一個。這是一些虛擬代碼。總之我想用文件路徑填充arrayList，然後加載它們。LOG4J2使用多個配置文件使用java

public class LoggerConfiguratorManager 
{ 
public static final String LOG4J_PATH = "etc/confs/logger.xml"; 

    private static LoggerContext context = null; 
    private static final ConfigurationFactory factory = XmlConfigurationFactory.getInstance(); 
    private static ConfigurationSource configurationSource = null; 
    private static Configuration configuration = null; 
    private static final ArrayList<String> registred_logger = new ArrayList<>(); 

    private static void loadLoggerConfig(String logger_path) 
    { 
    InputStream is = null; 
    try 
    { 
     if(logger_path.endsWith(".xml")) 
     is = new FileInputStream(logger_path); 
     else 
     { 
     final ZipFile archive = new ZipFile(logger_path); 
     final ZipEntry logger_entry = archive.getEntry(LOG4J_PATH); 
     if(logger_entry == null) throw new IOException("Cannot find 'logger.xml' in " + logger_path); 
     is = archive.getInputStream(logger_entry); 
     } 

     configurationSource = new ConfigurationSource(is); 
     configuration = factory.getConfiguration(configurationSource); 
    } 
    catch(IOException ex) 
    { 
     System.err.println("============================================================================="); 
     System.err.println("=============================== LOGGER CONFIG ==============================="); 
     System.err.println("============================================================================="); 
     System.err.println("=== [ERROR] " + ex); 
    } 
    finally 
    { 
     if (configurationSource != null) 
     { 
     context = Configurator.initialize(null, configurationSource); 
     context.start(configuration); 
     try { is.close(); } catch(IOException ex) { } 
     } 
    } 
    } 

    public static void load() 
    { 
    registred_logger.add(Globals.getClassLocation(LoggerConfiguratorManager.class)); 

    for(final String conf : registred_logger) 
     loadLoggerConfig(conf); 
    } 

    public static void regLoggerConf(String conf_path) { registred_logger.add(conf_path); }

我建議做，而不是：

public class LoggerConfiguratorManager { 

    private static final String LOG4J_PATH = "etc/confs/log4j2.xml"; 
    private static final StringBuffer paths = new StringBuffer(LOG4J_PATH); 

    public static void registerConfiguration(String confPath) { 
     paths.append(",").append(confPath); 
    } 

    public static void initLog4j() { 
     Configurator.initializer("My Config", null, paths.toString(), null); 
    } 
    }

這工作，但在我的情況下，該文件是在另一個程序裏面，即在一個jar檔案螞蟻這不會幫助我:(任何其他建議。 –

你是如何找到該文件？ – rgoers

你可以看到我的代碼我首先獲取當前類文件的路徑，然後使用ZipEntry並將整個logger.xml導入InputStream –
