Method Details

setLoggerName

public void setLoggerName(String loggerName)

This can be specified to not log into the category of this warner class but rather into a specific named category.

postProcessBeanFactory

public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
                            throws BeansException

Description copied from interface: BeanFactoryPostProcessor

Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

Specified by:

postProcessBeanFactory in interface BeanFactoryPostProcessor

Parameters:

beanFactory - the bean factory used by the application context

Throws:

BeansException - in case of errors

logDeprecatedBean

protected void logDeprecatedBean(String beanName,
 Class<?> beanType,
 BeanDefinition beanDefinition)

Logs a warning for a bean annotated with @Deprecated.

Parameters:

beanName - the name of the deprecated bean

beanType - the user-specified type of the deprecated bean

beanDefinition - the definition of the deprecated bean

writeToLog

protected void writeToLog(String message)

Actually write to the underlying log.

The default implementations logs the message at "warn" level.

Parameters:

message - the message to write

isLogEnabled

protected boolean isLogEnabled()

Determine whether the logger field is enabled.

Default is true when the "warn" level is enabled. Subclasses can override this to change the level under which logging occurs.
