Lifecycle Hooks

Lifecycle hooks allow you to hook into lifecycle events of the servlet/resource creation and REST calls.

For example, if you want to add an initialization method to your resource:

@Rest(...)
public class MyResource extends BasicRestResource {

    // Our database.
    private Map myDatabase;

    @RestInit
    public void initMyDatabase() throws Exception {
        myDatabase = new LinkedHashMap();
    }
}

10.0 change

Any lifecycle snippet using RestContext.Builder / RestOpContext.Builder parameters is pre-10.0 and kept only for historical context. Builder injection was removed; migrate to @Rest(...) / @RestOp(...) attributes and @Bean(name="...") bean suppliers. See the V10 Migration Guide.

Or if you want to intercept REST calls:

@Rest(...)
public class MyResource extends BasicRestResource {

    // Add a request attribute to all incoming requests.
    @RestPreCall
    public void onPreCall(RestRequest req) {
        req.setAttribute("foo", "bar");
    }
}

The following lifecycle annotations are provided:

Resource lifecycle events:RestInit - Right before initialization.RestPostInit - Right after initialization.RestDestroy - Right before servlet destroy.REST call lifecycle events:RestStartCall - At the beginning of a REST call.RestPreCall - Right before the @RestOp method is invoked.RestPostCall - Right after the @RestOp method is invoked.RestEndCall - At the end of the REST call after the response has been flushed.
