    从类复制的说明: LoggingSystem
    Reset the logging system to be limit output. This method may be called before LoggingSystem.initialize(LoggingInitializationContext, String, LogFile) to reduce logging noise until the system has been fully initialized.
    指定者:
    beforeInitialize 在类中 LoggingSystem
  - initialize
```
public void initialize(LoggingInitializationContext initializationContext,
                       String configLocation,
                       LogFile logFile)
```
    从类复制的说明: LoggingSystem
    Fully initialize the logging system.
    覆盖:
    initialize 在类中 LoggingSystem
    参数:
    initializationContext - the logging initialization context
    configLocation - a log configuration location or null if default initialization is required
    logFile - the log output file that should be written or null for console only output
  - getSelfInitializationConfig
```
protected String getSelfInitializationConfig()
```
    Return any self initialization config that has been applied. By default this method checks getStandardConfigLocations() and assumes that any file that exists will have been applied.
    返回:
    the self initialization config or null
  - getSpringInitializationConfig
```
protected String getSpringInitializationConfig()
```
    Return any spring specific initialization config that should be applied. By default this method checks getSpringConfigLocations().
    返回:
    the spring initialization config or null
  - getStandardConfigLocations
```
protected abstract String[] getStandardConfigLocations()
```
    Return the standard config locations for this system.
    返回:
    the standard config locations
    另请参阅:
    getSelfInitializationConfig()
  - getSpringConfigLocations
```
protected String[] getSpringConfigLocations()
```
    Return the spring config locations for this system. By default this method returns a set of locations based on getStandardConfigLocations().
    返回:
    the spring config locations
    另请参阅:
    getSpringInitializationConfig()
  - loadDefaults
```
protected abstract void loadDefaults(LoggingInitializationContext initializationContext,
                                     LogFile logFile)
```
    Load sensible defaults for the logging system.
    参数:
    initializationContext - the logging initialization context
    logFile - the file to load or null if no log file is to be written
  - loadConfiguration
```
protected abstract void loadConfiguration(LoggingInitializationContext initializationContext,
                                          String location,
                                          LogFile logFile)
```
    Load a specific configuration.
    参数:
    initializationContext - the logging initialization context
    location - the location of the configuration to load (never null)
    logFile - the file to load or null if no log file is to be written
  - reinitialize
```
protected void reinitialize(LoggingInitializationContext initializationContext)
```
    Reinitialize the logging system if required. Called when getSelfInitializationConfig() is used and the log file hasn't changed. May be used to reload configuration (for example to pick up additional System properties).
    参数:
    initializationContext - the logging initialization context
  - getClassLoader
```
protected final ClassLoader getClassLoader()
```
  - getPackagedConfigFile
```
protected final String getPackagedConfigFile(String fileName)
```
  - applySystemProperties
```
protected final void applySystemProperties(org.springframework.core.env.Environment environment,
                                           LogFile logFile)
```
