    从接口复制的说明: Log
    Is fatal logging currently enabled?
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than fatal.
    指定者:
    isFatalEnabled 在接口中 Log
    返回:
    true if fatal is enabled in the underlying logger.

  - isDebugEnabled
```
public boolean isDebugEnabled()
```
    从接口复制的说明: Log
    Is debug logging currently enabled?
    Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.
