方法详细资料

beforeInitialize

public void beforeInitialize()

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(Environment environment,
 LogFile logFile)

getDefaultValueResolver

protected Function<String,String> getDefaultValueResolver(Environment environment)

Return the default value resolver to use when resolving system properties.

参数:

environment - the environment

返回:

the default value resolver

从以下版本开始:

3.2.0

getDefaultLogCorrelationPattern

protected String getDefaultLogCorrelationPattern()

Return the default log correlation pattern or null if log correlation patterns are not supported.

返回:

the default log correlation pattern

从以下版本开始:
