All Implemented Interfaces:
EntityResolver
```
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.
