Spring API allows 3rd party plugins to re-use, integrate with or extend existing Spring Framework support in IntelliJ IDEA.
Using Spring-API
To develop plugins integrating with Spring-API you will need to use IntelliJ IDEA Ultimate Edition version 13.1 (or higher).
Setting up IntelliJ Platform SDK
New SDK
Please create an IntelliJ Platform SDK to include all minimum required files.
Then add $IDEA_HOME$/plugins/Spring/lib/spring.jar
to its classpath (not to your plugin module's dependencies).
Existing SDK
Follow these steps to modify existing IntelliJ Platform SDK:
- add to classpath (not to your plugin module's dependencies)
$IDEA_HOME$/plugins/Spring/lib/spring-api.jar
$IDEA_HOME$/plugins/Spring/lib/spring.jar
- add to sourcepath
$IDEA_HOME$/lib/src/src_spring-openapi.zip
General Notes
If you use other Spring functionality (e.g. Spring EL) in your plugin, make sure to add all required JARs to your IntelliJ Platform SDK classpath to make your plugin's tests work.
Please use only Spring-related functionality exposed in spring-api.jar
(where sources are provided) in your plugin. Using any other "internal" (implementation) classes from Spring plugin itself (spring.jar
) is not supported.
plugin.xml
Add <depends>com.intellij.spring</depends>
to your plugin.xml
to require "Spring Support" plugin to be activated. All available extension points are provided under com.intellij.spring
prefix.
Note that "Spring Support" plugin itself has dependencies to a few other plugins which need to be enabled in your sandbox (see notifications on startup).
Main concepts
A Spring facet can be attached on a Module. (Nearly) All Spring functionality requires an existing and properly setup Spring facet.
Spring facets usually contain one more user-configured or automatically provided filesets, which group a set of Spring related configuration files (XML, Code or .properties files).
A fileset usually corresponds to an actual application context configuration at runtime. Hierarchies can be modeled by depending on another fileset (possibly from another module).
As an API-user, you will usually rather work with SpringModel
(which is built on top of fileset(s)).
API updates
Note Starting with 2016.2, internal representation of bean type has been changed from
PsiClass
toPsiType
, please note deprecations.Note Some core classes have been changed in 14(.1), please see "Version 14(.1)" notes for info on how to replace existing API-calls.
How do I...
Spring Setup
To check availability of Spring/Spring Facet etc. see com.intellij.spring.model.utils.SpringCommonUtils
.
2016.2 See com.intellij.spring.SpringLibraryUtil
to obtain information about exact version of Spring in use.
Spring Model
Obtain Spring Model by file, PsiElement, ..
See SpringManager#getSpringModel(s)...
and com.intellij.spring.model.utils.SpringModelUtils
.
Contribute implicit model(s)
See com.intellij.spring.SpringModelProvider
to provide implicit filesets (e.g. provided by another framework in specific configuration file).
Version 15
See com.intellij.spring.facet.SpringAutodetectedFileSet
for a convenient base class. Please note that autodetected filesets cannot be edited/modified by users in Spring facet.
Customize implicit models configuration
2017.1 See com.intellij.spring.facet.SpringFileSetEditorCustomization
to customize presentation and/or add extra settings/actions for specific autodetected filesets.
Contribute implicit beans
See com.intellij.spring.model.jam.CustomComponentsDiscoverer
or com.intellij.spring.model.SpringImplicitBeansProviderBase
to provide implicit (framework-specific) beans (e.g. "servletContext" by Spring MVC).
Version 15
CustomComponentsDiscoverer
has been split into com.intellij.spring.model.custom.CustomLocalComponentsDiscoverer
and com.intellij.spring.model.custom.CustomModuleComponentsDiscoverer
respectively.
Contribute custom bean scope
Version 14
See com.intellij.spring.model.scope.SpringCustomBeanScope
to provide custom (e.g. framework specific) bean scopes.
Obtain/Create Spring Profiles
Version 14.1
com.intellij.spring.profiles.SpringProfilesFactory
Beans
Search for bean by name
com.intellij.spring.CommonSpringModel#findBeanByName
Version 14: com.intellij.spring.model.utils.SpringModelSearchers#findBean
Search for beans by type
Choose one of com.intellij.spring.CommonSpringModel#findBeansByPsiClassXXX
variants (please note deprecated methods).
Version 14: com.intellij.spring.model.utils.SpringModelSearchers#findBeans
Version 16: note deprecation of SpringModelSearchParameters.BeanClass#withInheritors(GlobalSearchScope)
Find out if bean with given name/type exists
Version 14: com.intellij.spring.model.utils.SpringModelSearchers#doesBeanExist
(please note deprecated methods)
Mark bean as infrastructure bean
Version 14: implement SpringInfrastructureBean
, such beans obtain special icon and can be filtered in various places in UI.
XML Configuration
All support for XML-based Spring configuration files is provided via DOM-API.
Add support for additional Spring namespace
See EP com.intellij.spring.dom.SpringCustomNamespaces
, registered namespace-key must match the one registered with your DOM elements via @Namespace
.
Register available elements via standard DomExtender<Beans>
EP or com.intellij.spring.dom.SpringCustomNamespaces#registerExtensions
(Version 14).
Please pay attention to getModelVersion
and getStubVersion
(see javadoc).
Add reference to Spring Bean in my DomElement
Use the following template:
@Convert(SpringBeanResolveConverter.class)
@RequiredBeanType("fqn.to.required.class") // optional
GenericAttributeValue<SpringBeanPointer> getMyAttributeName();
Code Configuration
Add reference to Spring Bean in my JamElement
Version 14
JamStringAttributeMeta.Single<SpringBeanPointer> ATTRIBUTE_META =
JamAttributeMeta.singleString("attributeName",
new SpringBeanReferenceJamConverter("fqn.to.required.class"));
@AliasFor
Version 16
See com.intellij.spring.model.aliasFor.SpringAliasForUtils
to obtain corresponding @AliasFor
JAM.
spring.factories
Version 15
See com.intellij.spring.spi.SpringSpiManager
.
IDE features
Add inspections to Spring Validator
Add additional inspections (e.g. for custom namespace) to Spring Validator (Settings|Compiler|Validation) via EP com.intellij.spring.SpringInspectionsRegistry$Contributor
.
Add additional files to Spring Validator
Version 14.1
Additional files to be processed by inspections registered with Spring Validator (e.g. specific .properties
configuration files) can be registered via com.intellij.spring.SpringInspectionsRegistry$AdditionalFilesContributor
Configure Spring support for other frameworks
Use com.intellij.spring.facet.SpringConfigurator
to provide "automatic" configuration when Spring facet is added via framework wizard.
UI/Presentation
Please do not reference bean icons from SpringApiIcons
directly, but use SpringPresentationProvider
to re-use unified icon/bean name. See SpringBeansPsiElementCellRenderer
for popup/list renderer.
