| This sample illustrates the usage of the new DependencyManager annotations. |
| |
| Sample description: |
| |
| This sample shows a basic "SpellChecker" application which provides a Felix "spellcheck" GOGO shell |
| command. The GOGO "spellcheck" command accepts a string as parameter, which is checked for proper |
| existence. The SpellChecker class has a required/multiple (1..N) dependency over every available |
| "DictionaryService" services, which are internally used by the SpellChecker command, when checking |
| word existence. |
| |
| A DictionaryService is defined using a FactoryConfigurationAdapterService annotation, allowing to |
| instantiate many "DictionaryService" instances from webconsole. This annotation actually |
| registers a ManagedServiceFactory into the Registry, and you can specify some meta type |
| informations in the annotation, allowing to configure the DictionaryService words and language from |
| WebConsole. |
| Each time you instantiate a factory configuration whose factory pid equals "Dictionary Services", |
| then a corresponding "DictionaryService" service is instantiated and is then injected |
| into the SpellChecker service. So, before testing, you first have to go to webconsole |
| Configuration panel, and specify some dictionaries (see the "Dictionary Services" Factory PID). |
| Then, go to the felix GOGO shell, and you will then see the "spellcheck" command (when typing |
| "help"). |
| |
| Notice that in the sample, you will also find a DictionaryAspect Service (DictionaryAspect.java), which |
| decorates the EnglishDictionary service, by adding some additional words to it. |
| |
| How to test: |
| |
| - Install the following bundles (with same or higher version): |
| |
| org.apache.felix.configadmin-1.2.8.jar |
| org.apache.felix.metatype-1.0.4.jar |
| org.apache.felix.http.jetty-2.0.4.jar |
| org.apache.felix.webconsole-3.1.2.jar |
| |
| - compile dependency manager from trunk: |
| |
| svn checkout http://svn.apache.org/repos/asf/felix/trunk/dependencymanager dependencymanager |
| cd dependencymanager |
| mvn -Dpackaging=plugins -Dmaven.test.skip=true install |
| |
| - install the DM bundles into the fwk |
| |
| dependencymanager/core/target/org.apache.felix.dependencymanager-3.0.0-SNAPSHOT.jar |
| dependencymanager/shell/target/org.apache.felix.dependencymanager.shell-3.0.0-SNAPSHOT.jar |
| dependencymanager/runtime/target/org.apache.felix.dependencymanager.runtime-3.0.0-SNAPSHOT.jar |
| dependencymanager/samples.annotation/target/org.apache.felix.dependencymanager.samples.annotation-3.0.0-SNAPSHOT.jar |
| |
| - Start felix |
| |
| At this point, you should have the following running bundles: |
| |
| START LEVEL 1 |
| ID|State |Level|Name |
| 0|Active | 0|System Bundle (3.0.1) |
| 1|Active | 1|Apache Felix Bundle Repository (1.6.2) |
| 7|Active | 1|Apache Felix Gogo Command (0.6.0) |
| 8|Active | 1|Apache Felix Gogo Runtime (0.6.0) |
| 9|Active | 1|Apache Felix Gogo Shell (0.6.0) |
| 10|Active | 1|Apache Felix Http Jetty (2.0.4) |
| 11|Active | 1|Apache Felix Metatype Service (1.0.4) |
| 12|Active | 1|Apache Felix Web Management Console (3.1.2) |
| 2|Active | 1|Apache Felix Configuration Admin Service (1.2.4) |
| 3|Active | 1|Apache Felix Dependency Manager (3.0.0.SNAPSHOT) |
| 6|Active | 1|Apache Felix Dependency Manager Shell (3.0.0.SNAPSHOT) |
| 4|Active | 1|Apache Felix Dependency Manager Runtime (3.0.0.SNAPSHOT) |
| 5|Active | 1|Apache Felix Dependency Manager Annotation Sample (3.0.0.SNAPSHOT) |
| |
| - Go to web console: in the Configuration panel, edit the "Dictionary Services" |
| Configuration, add some dictionaries. By default, an English dictionary is displayed. Just |
| click on "save", *then click on your refresh web browser*: you will see a new dictionary service |
| instance. At this point, a DictionaryService service will be enabled (with the service property "lang=en"), |
| and the SpellCheck component will be injected with it. Then you should see the "spellcheck" |
| command, when typing "help" on the gogo shell. |
| |
| - Just type "spellcheck hello", and the command should reply a fantastic message, like "word hello is correct". |
| |
| - You can also click on the "Aspect Dictionary" button, in order to decorate the english dictionary with some |
| custom words. |
| By default, the "aspect" word is pre configured, but you can click on the "+" button in order to add more words. |
| Then click on Save. At this point, the English DictionaryService will be decorated with the aspect service. |
| So, now, if you type "spellcheck aspect", then the message: "word aspect is correct" should be displayed. |
