java.lang.Object org.springframework.beans.factory.xml.PluggableSchemaResolver
public class PluggableSchemaResolver
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 overidden using the
PluggableSchemaResolver(ClassLoader, String)
constructor
