系统日志 EJB Java EE
Syslog EJB Java EE
我希望 Glassfish 服务器中的所有应用程序在进入 syslog 输出时都有一个单一的点。我找到了一个处理 Syslog 输出的库 (https://github.com/CloudBees-community/syslog-java-client)，我已经完成了这项工作。但这需要每个应用程序都有自己的 ILogger 实现：
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);
}
所以我想要一个 return 这个 ILogger 实现的 bean，像这样：
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);
}
到目前为止，我的实施导致异常：

除非您绝对需要使用该库，否则我建议您查看 Logback or other libraries that support the Simple Logging Facade for Java. That will give you far more options and flexibility. The Syslog Appender 开箱即用的 Logback。
