Method Detail

isAttachedConfigurationPropertySource

public static boolean isAttachedConfigurationPropertySource(PropertySource<?> propertySource)

Determines if the specific PropertySource is the ConfigurationPropertySource that was attached to the Environment.

Parameters:

propertySource - the property source to test

Returns:

true if this is the attached ConfigurationPropertySource

attach

public static void attach(Environment environment)

Attach a ConfigurationPropertySource support to the specified Environment. Adapts each PropertySource managed by the environment to a ConfigurationPropertySource and allows classic PropertySourcesPropertyResolver calls to resolve using configuration property names.

The attached resolver will dynamically track any additions or removals from the underlying Environment property sources.

Parameters:

environment - the source environment (must be an instance of ConfigurableEnvironment)

See Also:

get(Environment)

get

public static Iterable<ConfigurationPropertySource> get(Environment environment)

Return a set of ConfigurationPropertySource instances that have previously been attached to the Environment.

Parameters:

environment - the source environment (must be an instance of ConfigurableEnvironment)

Returns:

an iterable set of configuration property sources

Throws:

IllegalStateException - if not configuration property sources have been attached

from

public static Iterable<ConfigurationPropertySource> from(PropertySource<?> source)

Return Iterable containing a single new ConfigurationPropertySource adapted from the given Spring PropertySource.

Parameters:

source - the Spring property source to adapt

Returns:

an Iterable containing a single newly adapted SpringConfigurationPropertySource

from

public static Iterable<ConfigurationPropertySource> from(Iterable<PropertySource<?>> sources)

Return Iterable containing new ConfigurationPropertySource instances adapted from the given Spring PropertySources.

This method will flatten any nested property sources and will filter all stub property sources. Updates to the underlying source, identified by changes in the sources returned by its iterator, will be automatically tracked. The underlying source should be thread safe, for example a MutablePropertySources

Parameters:

sources - the Spring property sources to adapt

Returns:

an Iterable containing newly adapted SpringConfigurationPropertySource instances
