addPropertiesFilesToEnvironment

public static void addPropertiesFilesToEnvironment(ConfigurableApplicationContext context,
                                                   java.lang.String[] locations)

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

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

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

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:

java.lang.IllegalStateException - if an error occurs while processing a properties file

Since:

4.1.5

addInlinedPropertiesToEnvironment

public static void addInlinedPropertiesToEnvironment(ConfigurableApplicationContext context,
                                                     java.lang.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

addInlinedPropertiesToEnvironment

public static void addInlinedPropertiesToEnvironment(ConfigurableEnvironment environment,
                                                     java.lang.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(java.lang.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

convertInlinedPropertiesToMap

public static java.util.Map<java.lang.String,java.lang.Object> convertInlinedPropertiesToMap(java.lang.String[] inlinedProperties)

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

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

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:

java.lang.IllegalStateException - if a given key-value pair cannot be parsed, or if a given inlined property contains multiple key-value pairs

Since:

4.1.5
