Syslog EJB Java EE

Ich möchte alle Anwendungen in einem Glassfish-Server einen einzigen Punkt bei der Eingabe der Syslog-Ausgabe haben. Ich habe eine Bibliothek gefunden (https://github.com/CloudBees-community/syslog-java-client), die die Syslog-Ausgabe verarbeitet, und ich habe dies funktioniert. Aber dies erforderlich jede Anwendung ihre eigene Implementierung von ILogger haben:Syslog EJB Java EE

public interface ILogger extends Serializable { 
    public void alert(String message); 
    public void critical(String message); 
    public void debug(String message); 
    public void emergency(String message); 
    public void error(String message); 
    public void informational(String message); 
    public void notice(String message); 
    public void warning(String message); 
    public void exception(Exception e); 
}

Deshalb möchte ich eine Bohne haben, die Implementierungen dieser ILogger, so etwas wie dies zurück:

public interface ILoggerFacade extends Serializable { 
    // beanName is the name of the bean requesting a Logger 
    public ILogger get(String beanName); 
    public void log(String beanName, int severity, String message); 
}

Bisher meine Implementierungen führen in Ausnahmen:

Implementations bisher:

Logger

@SuppressWarnings("serial") 
public class Logger implements ILogger { 
private final ILoggerFacade loggerFacade; 
private final String bean; 

public Logger(ILoggerFacade loggerFacade, String bean) throws NamingException { 
    //this.loggerFacade = InitialContext.doLookup("java:global/QcastORM/logger/LoggerBean"); 
    //loggerFacade = null; 
    this.loggerFacade = loggerFacade; 
    this.bean = bean; 
} 

@Override 
public void alert(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void critical(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void debug(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void emergency(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void error(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void informational(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void notice(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void warning(String message) { 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), message); 
} 

@Override 
public void exception(Exception e) { 
    // TODO stacktrace uitschrijven 
    loggerFacade.log(bean, Severity.ALERT.numericalCode(), e.toString()); 
} 
}

LoggerFacade

@SuppressWarnings("serial") 
@EJB(name = "samename", beanInterface = ILoggerFacade.class) 
@Stateless 
@TransactionManagement(TransactionManagementType.BEAN) 
@Remote 
public class LoggerFacade implements ILoggerFacade { 

    @Override 
    public ILogger get(String bean) { 
     // This is not ideal 
     try { 
      return new Logger(this, bean); 
     } catch (NamingException e) { 
      e.printStackTrace(); 
      return null; 
     } 
    } 

    @Override 
    public void log(String bean, int severity, String message) { 
     // When this works, change syso into syslog 
     System.out.println(message); 
    } 
}

Ich habe Google gesucht und SO, aber bisher habe ich keine Lösungen gefunden ich bin zufrieden mit. Meine Frage ist, ob ich anders darüber nachdenken sollte oder ein Beispiel dafür, wie dies erreicht wird.

Vielen Dank im Voraus!

Können Sie uns Ihre vollständige Ausnahme und die Implementierung der Schnittstellen zeigen? –

Ich habe sie hinzugefügt –

Welche Methode rufen Sie von LoggerFacade? –

Antwort

1

Sofern Sie diese Bibliothek nicht unbedingt verwenden müssen, würde ich empfehlen, Logback oder andere Bibliotheken, die die Simple Logging Facade for Java unterstützen. Das gibt Ihnen viel mehr Möglichkeiten und Flexibilität. Die Syslog Appender ist standardmäßig für Logback verfügbar.

Danke für den Kopf! Wie wird es das Problem lösen, vor dem ich stehe? –

Es bietet Ihren Programmen einen einzigen Einstiegspunkt für syslog.Sie haben Interesse an alternativen Lösungen bekundet - dies ist der Standard für diese Situation und einfacher. –
