MyEclipse for Spring Reference – Annotators
1. Annotators in Spring Development
Annotators are part of the code assistants available in MyEclipse with Spring support, and annotators help developers with annotation-based development. While most Java developers understand how to technically use Java annotations, it’s not always clear which annotations are available for a specific technology and when a particular annotation should be used. For example, the Spring framework has excellent support for annotation-based programming; however there are a lot of supported annotations. Some annotations are applicable to all Spring stereotypes, and other annotations are applicable only to specific stereotypes. Annotators support annotation-based development by helping a developer understand what annotations are available and in what context the annotation should be used.
Note: Spring scaffolding requires a MyEclipse Spring or Bling subscription.
2. Spring Annotator
The Spring Annotator guides you with configuring Spring stereotyped components, including controller, service, component and repository.
2.1 Spring Controller Annotator
The Spring Controller Annotator is for configuring Spring controllers. The annotator shows annotation and configuration options relevant to Spring @Controller.
2.1.1 Spring Controller – Class-level Annotations
When the class name is selected from the outline, the Controller tab lets you configure the class-level annotations for Spring controllers, and the Transactional tab lets you enable and configure the transactional properties of the controller.
2.1.2 Spring Controller – Variable-level Annotations
When the class variable is selected from the outline, the Controller tab will let you configure the variable-level annotations for Spring controllers.
2.1.3 Spring Controller – Method-level Annotations
When the class method is selected from the outline, the Controller tab lets you configure the method-level annotations for Spring controllers, and the Transactional tab lets you enable and configure the transactional properties of the controller method.
2.2 Spring Service Annotator
The Spring Service Annotator is for configuring Spring services. The annotator shows you annotation and configuration options relevant to Spring @Service.
2.2.1 Spring Service – Class-level Annotations
When the class name is selected from the outline, the Service tab lets you configure the class-level annotations for Spring services, and the Transactional tab lets you enable and configure the transactional properties of the service.
2.2.2 Spring Service – Variable-level Annotations
When the class variable is selected from the outline, the Service tab lets you configure the variable-level annotations for Spring services.
2.2.3 Spring Service – Method-level Annotations
When the class method is selected from the outline, the Service tab lets you enable and configure the transactional properties of Spring service methods.
2.3 Spring Component Annotator
The Spring Component Annotator is for configuring Spring components. The annotator shows you annotation and configuration options relevant to Spring @Component.
2.3.1 Spring Component – Class-level Annotations
When the class name is selected from the outline, the Component tab lets you configure the class-level annotations for Spring components, and the Transactional tab lets you enable and configure the transactional properties of the component.
2.3.2 Spring Component – Variable-level Annotations
When the class variable is selected from the outline, the Component tab lets you configure the variable-level annotations for Spring components.
2.3.3 Spring Component – Method-level Annotations
When the class method is selected from the outline, the Component tab lets you enable and configure the transactional properties of Spring component methods.
2.4 Spring Repository Annotator
The Spring Repository Annotator is for configuring Spring repositories. The annotator shows annotation and configuration options relevant to Spring @Repository.
2.4.1 Spring Repository – Class-level Annotations
When the class name is selected from the outline, the Repository tab lets you configure the class-level annotations for Spring repositories, and the Transactional tab lets you enable and configure the transactional properties of the repository.
Spring Annotations Repository tab2.4.2 Spring Repository – Variable-level Annotations
When the class variable is selected from the outline, the Repository tab lets you configure the variable-level annotations for Spring repositories.
2.4.3 Spring Repository – Method-level Annotations
When the class method is selected from the outline, the Component tab lets you enable and configure the transactional properties of Spring component methods.
3. JAX-WS Annotator
The JAX-WS Annotator is for configuring JAX-WS services. The annotator show annotation and configuration options that are relevant to JAX-WS.
The JAX-WS annotator helps expose a Spring service (@Service) as a SOAP web service (often referred to as Contract-Last development or Code-First development), and the JAX-WS annotator also provides an Eclipse view for maintaining all JAX-WS web service annotations.
3.1 JAX-WS – Class-level annotations – Web Service
When the class name is selected from the outline, the Web Service tab lets you configure the class-level web service annotations for JAX-WS services.
3.2 JAX-WS – Class-level annotations – SOAP Binding
When the class name is selected from the outline, the SOAP Binding tab lets you configure the class-level SOAP binding annotations for JAX-WS services.
3.3 JAX-WS – Method-level annotations – Web Method
When the class method is selected from the outline, the Web Method tab lets you configure the method-level Web Method annotations for JAX-WS services.
3.4 JAX-WS – Method-level annotations – SOAP Binding
When the class method is selected from the outline, the SOAP Binding tab lets you configure the method-level SOAP binding annotations for JAX-WS services.
3.5 JAX-WS – Method-level annotations – Request Wrapper
When the class method is selected from the outline, the Request Wrapper tab lets you configure the method-level Request Wrapper annotations for JAX-WS services.
3.6 JAX-WS – Method-level annotations – Response Wrapper
When the class method is selected from the outline, the Response Wrapper tab lets you configure the method-level Response Wrapper annotations for JAX-WS services.
3.7 JAX-WS – Method-level annotations – Parameters
When the class method is selected from the outline, the Parameters tab lets you configure the method-level parameter annotations for JAX-WS services.
3.8 JAX-WS – Method-level annotations – Web Result
When the class method is selected from the outline, the Web Result tab lets you configure the method-level Web result annotations for JAX-WS services.
4. JPA Annotator
The JPA Annotator is for configuring JPA entities. The annotator shows annotation and configuration options that are relevant to JPA.
4.1 JPA – Class-level annotations – Entity
When the class name is selected from the outline, the Entity tab lets you configure the class-level annotations for JPA.
4.2 JPA – Class-level annotations – Named Queries
When the class name is selected from the outline, thee NamedQueries tab lets you configure the class-level annotations for JPA.
4.3 JPA – Class-level annotations – Named Native Queries
When the class name is selected from the outline, the NamedNativeQueries tab lets you configure the class-level annotations for JPA.
4.4 JAX-WS – JPA – Variable-level annotations – Basic
When the class variable is selected from the outline, the editor lets you configure the variable-level.
4.5 JPA – Variable-level annotations – Relationships
When the class variable is selected from the outline, the editor lets you configure the variable-level.
