Package org.eclipse.jetty.osgi.annotations

Class AnnotationConfiguration

java.lang.Object

org.eclipse.jetty.webapp.AbstractConfiguration

org.eclipse.jetty.annotations.AnnotationConfiguration

org.eclipse.jetty.osgi.annotations.AnnotationConfiguration

All Implemented Interfaces:

Configuration

public class AnnotationConfiguration
extends AnnotationConfiguration

Extend the AnnotationConfiguration to support OSGi: Look for annotations inside WEB-INF/lib and also in the fragments and required bundles. Discover them using a scanner adapted to OSGi instead of the jarscanner.

Constructor Details

AnnotationConfiguration

public AnnotationConfiguration()

Method Details

replaces

public Class<? extends Configuration> replaces()

Description copied from interface: Configuration

Get a class that this class replaces/extends. If this is added to Configurations collection that already contains a configuration of the replaced class or that reports to replace the same class, then it is replaced with this instance.

Returns:

The class this Configuration replaces/extends or null if it replaces no other configuration

createAnnotationParser

protected AnnotationParser createAnnotationParser(int javaTargetVersion)

This parser scans the bundles using the OSGi APIs instead of assuming a jar.

Overrides:

createAnnotationParser in class AnnotationConfiguration

Parameters:

javaTargetVersion - The java platform to scan for.

Returns:

a new AnnotationParser. This method can be overridden to use a different implementation of the AnnotationParser. Note that this is considered internal API.

getJarFor

public Resource getJarFor(javax.servlet.ServletContainerInitializer service)
                   throws MalformedURLException,
IOException

Overrides:

getJarFor in class AnnotationConfiguration

Throws:

MalformedURLException

IOException

parseWebInfLib

public void parseWebInfLib(WebAppContext context,
 AnnotationParser parser)
                    throws Exception

Here is the order in which jars and osgi artifacts are scanned for discoverable annotations.

1. The container jars are scanned.
2. The WEB-INF/classes are scanned
3. The osgi fragment to the web bundle are parsed.
4. The WEB-INF/lib are scanned
5. The required bundles are parsed

Overrides:

parseWebInfLib in class AnnotationConfiguration

Parameters:

context - the context for the scan

parser - the annotation parser to use

Throws:

Exception - if unable to scan and/or parse

parseFragmentBundle

protected void parseFragmentBundle(WebAppContext context,
 AnnotationParser parser,
 org.osgi.framework.Bundle webbundle,
 org.osgi.framework.Bundle fragmentBundle)
                            throws Exception

Scan a fragment bundle for servlet annotations

Parameters:

context - The webapp context

parser - The parser

webbundle - The current webbundle

fragmentBundle - The OSGi fragment bundle to scan

Throws:

Exception - if unable to parse fragment bundle

parseWebBundle

protected void parseWebBundle(WebAppContext context,
 AnnotationParser parser,
 org.osgi.framework.Bundle webbundle)
                       throws Exception

Scan a bundle required by the webbundle for servlet annotations

Parameters:

context - The webapp context

parser - The parser

webbundle - The current webbundle

Throws:

Exception - if unable to parse the web bundle

parseWebInfClasses

public void parseWebInfClasses(WebAppContext context,
 AnnotationParser parser)
                        throws Exception

Description copied from class: AnnotationConfiguration

Scan classes in WEB-INF/classes.

Overrides:

parseWebInfClasses in class AnnotationConfiguration

Parameters:

context - the context for the scan

parser - the annotation parser to use

Throws:

Exception - if unable to scan and/or parse

parseRequiredBundle

 AnnotationParser parser,
 org.osgi.framework.Bundle webbundle,
 org.osgi.framework.Bundle requiredBundle)
                            throws Exception

Scan a bundle required by the webbundle for servlet annotations

Parameters:

context - The webapp context

parser - The parser

webbundle - The current webbundle

requiredBundle - The OSGi required bundle to scan

Throws:

Exception - if unable to parse the required bundle

parseBundle

protected void parseBundle(WebAppContext context,
