## Architecture Patterns

### Action (Controller)
- Hierarchy: `TypicalAction` → `FessBaseAction` → `FessAdminAction`/`FessSearchAction`
- `@Execute` marks web endpoints
- `@Resource` for DI
- `@Secured({ "role", "role-view" })` for authorization
- Return `HtmlResponse` for JSP, `JsonResponse` for APIs

### Service
- Inject behaviors (Bhv) for data access

	var clnts []*bootstrapRESTClient
	for _, ep := range endpointServerPools {
		for _, endpoint := range ep.Endpoints {
			if endpoint.IsLocal {
				continue
			}
			if seenClient.Contains(endpoint.Host) {
				continue
			}
			seenClient.Add(endpoint.Host)
			clnts = append(clnts, &bootstrapRESTClient{gm.Connection(endpoint.GridHost())})
		}
	}
	return clnts

	}
