Syslog EJB Java EE

我希望Glassfish服務器中的所有應用程序在進入syslog輸出時都有一個單獨的點。我找到了一個處理Syslog輸出的庫（https://github.com/CloudBees-community/syslog-java-client），並且我做了這個工作。但是，這需要每個應用程序都有自己的執行ILogger的：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); 
}

所以我想有一個bean返回此ILogger的實現，這樣的事：

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); 
}

到目前爲止，我的實現產生在例外情況：

實現至今：

記錄儀

@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

} 

@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); 
    } 
}

我已搜查谷歌和SO但到目前爲止，我還沒有發現我很高興與任何解決方案。我的問題是，如果我應該以不同的方式思考這個問題或者說這是如何實現的例子。

在此先感謝！

你能告訴我們你的完整例外和接口的實現嗎？ –

您調用LoggerFacade的哪種方法？ –

除非您絕對需要使用該庫，否則我建議您查看Logback或其他支持Simple Logging Facade for Java的庫。這會給你更多的選擇和靈活性。 Logback的開箱即可使用Syslog Appender。

感謝您的領導！它將如何解決我面臨的問題？ –

它爲您的程序提供了一個進入syslog的單點。您對備用解決方案表現出了興趣 - 這是針對這種情況的標準解決方案，並且更簡單。 –
