Method Detail

newEmptyPropertyResolver

public static org.springframework.core.env.PropertyResolver newEmptyPropertyResolver()

Creates a new property resolver with no properties.

Returns:

new property resolver

newMapPropertyResolver

public static org.springframework.core.env.PropertyResolver newMapPropertyResolver(Map<String,String> m)

Creates a new property resolver that gets properties from the given map.

Parameters:

m - property map

Returns:

new property resolver

Throws:

NullPointerException - if the map is null

newMultiResourcePropertyResolver

public static org.springframework.core.env.PropertyResolver newMultiResourcePropertyResolver(String builtInResourceLocation,
                                                                                             String... customResourceLocations)
                                                                                      throws IOException

Creates a property resolver that pulls from multiple property resource locations. The first "built-in" location must be successfully loaded, but all other "custom" locations may fail to load.

Parameters:

builtInResourceLocation - lowest precedence, required resource location for properties

customResourceLocations - additional resource locations for properties, in increasing order of precedence

Returns:

new property resolver

Throws:

IOException - if the built-in resource location could not be loaded

NullPointerException - if any resource location is null

newMultiResourcePropertyResolver

public static org.springframework.core.env.PropertyResolver newMultiResourcePropertyResolver(boolean allowMissing,
                                                                                             String builtInResourceLocation,
                                                                                             String... customResourceLocations)
                                                                                      throws IOException

Creates a property resolver that pulls from multiple property resource locations. The first "built-in" location must be successfully loaded, but all other "custom" locations must load only if {code}allowMissing{code} is false.

Parameters:

allowMissing - true to allow custom resource locations to fail to load

builtInResourceLocation - lowest precedence, required resource location for properties

customResourceLocations - additional resource locations for properties, in increasing order of precedence

Returns:

new property resolver

Throws:

IOException - if the built-in resource location could not be loaded, or if {code}allowMissing{code} is false and any custom resource location fails to load

NullPointerException - if any resource location is null
