URL Mapping
The mapping of the URI path space is presented in the following table:
| URI path | Resource class | HTTP methods | Allowed values |
|---|---|---|---|
| /api/contact | ContactCardResource | GET, POST, DELETE | |
| /api/contact/{id} | ContactCardResource | GET, DELETE | id - positive number |
| /api/contact/search/{searchType}?q={searchValue} | SearchResource | GET | searchType - (name |
Application is configured by using web.xml, which registers javax.ws.rs.core.Application descendant to get classes and singletons from it (see class MyApplication). Bean Validation annotations are present on resource classes (see ContactCardResource, SearchResource) as well as on the domain class (see ContactCard).
