## Overview

#### Purpose and Entry Points
This is a Java Spring Boot service backed by MongoDB, packaged as a Maven artifact and deployable in Docker. The application entry point is `src/main/java/com/mt/springmongo/DemoApp.java`; it initializes the Spring application context and web runtime.

#### HTTP/API Layer
`src/main/java/com/mt/springmongo/UserController.java` and `src/main/java/com/mt/springmongo/UserResource.java` define the user-facing request boundary. They receive HTTP requests, coordinate user operations, and return responses. `src/main/java/com/mt/springmongo/WebConfig.java` is the web-layer configuration boundary, likely controlling MVC/CORS/static-resource behavior.

#### Domain Model
`src/main/java/com/mt/springmongo/User.java` is the central persisted domain entity. It represents the data exchanged between the HTTP layer and the Mongo persistence layer.

#### Persistence Layer
`src/main/java/com/mt/springmongo/UserRepository.java` is the repository abstraction for user records. It isolates controllers/resources from direct MongoDB access and relies on Spring Data MongoDB conventions/runtime integration.

Primary flow: HTTP request → `UserController`/`UserResource` → `UserRepository` → MongoDB → response serialization.

#### Configuration and Runtime Boundaries
`src/main/resources/application.yml` contains application-level runtime settings. `src/main/resources/bootstrap.yml` is an early Spring bootstrap configuration boundary, potentially for externalized configuration initialization. `src/main/resources/logback-spring.xml` configures application logging.

The material runtime is Spring Boot on the JVM, with Maven defined by `pom.xml` handling compilation, dependencies, and executable packaging.

#### UI/Static Delivery
`src/main/resources/templates/index.html` provides a server-delivered HTML template. Static browser assets are served from `src/main/resources/static`, including images under `src/main/resources/static/img`. This is a secondary presentation path alongside the user API layer.

#### Deployment and Infrastructure
MongoDB is the primary external data service. `docker-compose.yaml` defines the multi-container deployment topology, expected to connect the Spring Boot service with MongoDB. `Dockerfile` packages the service into an application image. `SpringBootMongo.yaml` provides an additional deployment manifest/configuration artifact.

CI execution is represented by `Jenkinsfile`, while `pom.xml` remains the authoritative build and dependency boundary.
