public class PluggableSchemaResolver extends Object implements EntityResolver
EntityResolver implementation that attempts to resolve schema URLs into
local classpath resources using a set of mappings files.
By default, this class will look for mapping files in the classpath using the
pattern: META-INF/spring.schemas allowing for multiple files to exist on
the classpath at any one time.
The format of META-INF/spring.schemas is a properties file where each line
should be of the form systemId=schema-location where schema-location
should also be a schema file in the classpath. Since systemId is commonly a
URL, one must be careful to escape any ':' characters which are treated as delimiters
in properties files.
The pattern for the mapping files can be overridden using the
PluggableSchemaResolver(ClassLoader, String) constructor.
