| RestServlet |
| |
| <p> |
| The {@link oajr.RestServlet} class is the entry point for your REST resources. |
| It extends directly from <l>HttpServlet</l> and is deployed like any other servlet. |
| </p> |
| <p> |
| When the servlet <l>init()</l> method is called, it triggers the code to find and process the <l>@RestResource</l> |
| annotations on that class and all child classes. |
| These get constructed into a {@link oajr.RestContext} object that holds all the configuration |
| information about your resource in a read-only object. |
| </p> |
| <p> |
| Most developers are not going to be using the <l>RestServlet</l> class itself, and instead will |
| extend from one of the preconfigured default servlets such as {@link oajr.BasicRestServlet}. |
| The <l>RestServlet</l> class by itself is not configured with any serializers and parsers, and therefore |
| not very useful on it's own. |
| However, the class does provide a couple of convenience methods to be aware of: |
| </p> |
| <ul class='javatree'> |
| <li class='jac'><c>{@link oajr.RestServlet} <jk>extends</jk> HttpServlet</c> |
| <ul> |
| <li class='jm'>{@link oajr.RestServlet#init(ServletConfig) init(ServletConfig)} - Can override to provide custom initialization. |
| <li class='jm'>{@link oajr.RestServlet#service(HttpServletRequest,HttpServletResponse) service(HttpServletRequest,HttpServletResponse)} - Can override to provide custom request handling. |
| <li class='jm'>{@link oajr.RestServlet#destroy() destroy()} - Can override to provide custom cleanup. |
| <li class='jm'>{@link oajr.RestServlet#getContext() getContext()} - Returns all aspects of the configuration of your resource pulled from all annotations on the class/parent-classes and methods. |
| <li class='jm'>{@link oajr.RestServlet#log(Level,String,Object...) log(Level,String,Object...)} - Convenience logging method. |
| <li class='jm'>{@link oajr.RestServlet#log(Level,Throwable,String,Object...) log(Level,Throwable,String,Object...)} - Convenience logging method. |
| </ul> |
| </ul> |
