Method Details

addPropertiesFilesToEnvironment

public static void addPropertiesFilesToEnvironment(org.springframework.context.ConfigurableApplicationContext context,
 String... locations)

Add the Properties files from the given resource locations to the Environment of the supplied context.

This method delegates to addPropertiesFilesToEnvironment(ConfigurableEnvironment, ResourceLoader, String...).

Parameters:

context - the application context whose environment should be updated; never null

locations - the resource locations of Properties files to add to the environment; potentially empty but never null

Throws:

IllegalStateException - if an error occurs while processing a properties file

Since:

4.1.5

See Also:

addPropertiesFilesToEnvironment

public static void addPropertiesFilesToEnvironment(org.springframework.core.env.ConfigurableEnvironment environment,
 org.springframework.core.io.ResourceLoader resourceLoader,
 String... locations)

Add the Properties files from the given resource locations to the supplied environment.

Property placeholders in resource locations (i.e., ${...}) will be resolved against the Environment.

A ResourcePatternResolver will be used to resolve resource location patterns into multiple resource locations.

Each properties file will be converted to a ResourcePropertySource that will be added to the PropertySources of the environment with the highest precedence.

Parameters:

environment - the environment to update; never null

resourceLoader - the ResourceLoader to use to load each resource; never null

locations - the resource locations of Properties files to add to the environment; potentially empty but never null

Throws:

IllegalStateException - if an error occurs while processing a properties file

Since:

4.3

addPropertySourcesToEnvironment

public static void addPropertySourcesToEnvironment(org.springframework.context.ConfigurableApplicationContext context,
 List<org.springframework.core.io.support.PropertySourceDescriptor> descriptors)

Add property sources for the given descriptors to the Environment of the supplied context.

This method delegates to addPropertySourcesToEnvironment(ConfigurableEnvironment, ResourceLoader, List).

Parameters:

context - the application context whose environment should be updated; never null

descriptors - the property source descriptors to process; potentially empty but never null

Throws:

IllegalStateException - if an error occurs while processing the descriptors and registering property sources

Since:

6.1

addPropertySourcesToEnvironment

public static void addPropertySourcesToEnvironment(org.springframework.core.env.ConfigurableEnvironment environment,
 org.springframework.core.io.ResourceLoader resourceLoader,
 List<org.springframework.core.io.support.PropertySourceDescriptor> descriptors)

Add property sources for the given descriptors to the supplied environment.

Property placeholders in resource locations (i.e., ${...}) will be resolved against the Environment.

A ResourcePatternResolver will be used to resolve resource location patterns into multiple resource locations.

Each PropertySource will be created via the configured PropertySourceFactory (or the DefaultPropertySourceFactory if no factory is configured) and added to the PropertySources of the environment with the highest precedence.

Parameters:

environment - the environment to update; never null

resourceLoader - the ResourceLoader to use to load resources; never null

descriptors - the property source descriptors to process; potentially empty but never null

Throws:

IllegalStateException - if an error occurs while processing the descriptors and registering property sources

6.1

addInlinedPropertiesToEnvironment

public static void addInlinedPropertiesToEnvironment(org.springframework.context.ConfigurableApplicationContext context,
 String... inlinedProperties)

Add the given inlined properties to the Environment of the supplied context.

This method simply delegates to addInlinedPropertiesToEnvironment(ConfigurableEnvironment, String[]).

Parameters:

context - the application context whose environment should be updated; never null

inlinedProperties - the inlined properties to add to the environment; potentially empty but never null

Since:

4.1.5

• TestPropertySource.properties()
• addInlinedPropertiesToEnvironment(ConfigurableEnvironment, String[])

addInlinedPropertiesToEnvironment

public static void addInlinedPropertiesToEnvironment(org.springframework.core.env.ConfigurableEnvironment environment,
 String... inlinedProperties)

Add the given inlined properties (in the form of key-value pairs) to the supplied environment.

All key-value pairs will be added to the Environment as a single MapPropertySource with the highest precedence.

For details on the parsing of inlined properties, consult the Javadoc for convertInlinedPropertiesToMap(String...).

Parameters:

environment - the environment to update; never null

inlinedProperties - the inlined properties to add to the environment; potentially empty but never null

Since:

4.1.5

• INLINED_PROPERTIES_PROPERTY_SOURCE_NAME

convertInlinedPropertiesToMap

public static Map<String,Object> convertInlinedPropertiesToMap(String... inlinedProperties)

Convert the supplied inlined properties (in the form of key-value pairs) into a map keyed by property name.

Parsing of the key-value pairs is achieved by converting all supplied strings into virtual properties files in memory and delegating to Properties.load(java.io.Reader) to parse each virtual file.

The ordering of property names will be preserved in the returned map, analogous to the order in which the key-value pairs are supplied to this method. This also applies if a single string contains multiple key-value pairs separated by newlines — for example, when supplied by a user via a text block.

For a full discussion of inlined properties, consult the Javadoc for TestPropertySource.properties().

Parameters:

inlinedProperties - the inlined properties to convert; potentially empty but never null

Returns:

a new, ordered map containing the converted properties

Throws:

IllegalStateException - if a given key-value pair cannot be parsed

4.1.5
