Spring Web MVC Tutorial

This tutorial demonstrates configuring Spring Web MVC Controllers within WoOF. This enables using an existing Spring Application out of the box within WoOF.

Spring Web MVC Controller

The Spring Web MVC Controller to be integrated is as follows:

@RestController
@RequestMapping("/rest")
public class SpringRestController {

	@Autowired
	private SpringDependency dependency;

	@GetMapping
	public ResponseModel get() {
		return new ResponseModel("GET " + this.dependency.getMessage());
	}

	@GetMapping("/path/{param}")
	public ResponseModel path(@PathVariable("param") String param) {
		return new ResponseModel(param);
	}

	@PostMapping("/update")
	public ResponseModel post(@RequestBody RequestModel request) {
		return new ResponseModel(request.getInput());
	}

}

With the request and response models:

@Data
@NoArgsConstructor
@AllArgsConstructor
public class RequestModel {

	private String input;
}

@Data
@NoArgsConstructor
@AllArgsConstructor
public class ResponseModel {

	private String message;
}

Configuring Spring Web MVC Controller

To configure using Spring Web MVC Controller instances within WoOF, add the following dependency:

		<dependency>
			<groupId>net.officefloor.spring</groupId>
			<artifactId>officespring_webmvc</artifactId>
		</dependency>

Spring will also need to be configured in officefloor/suppliers/Spring.yml:

source: SPRING
properties:
  configuration.class: net.officefloor.tutorial.springwebmvchttpserver.Application

The Spring Web MVC Controllers are then configured as REST endpoints. The following configures the GET rest endpoint:

get:
  resource: net.officefloor.tutorial.springwebmvchttpserver.SpringRestController
  procedure: SpringWebMvcController
  method: get

The path parameter endpoint:

path:
  resource: net.officefloor.tutorial.springwebmvchttpserver.SpringRestController
  procedure: SpringWebMvcController
  method: path

The PUT endpoint:

post:
  resource: net.officefloor.tutorial.springwebmvchttpserver.SpringRestController
  procedure: SpringWebMvcController
  method: post

The HTML page endpoint:

html:
  resource: net.officefloor.tutorial.springwebmvchttpserver.SpringController
  procedure: SpringWebMvcController
  method: html

Spring web pages

Integration of Spring Web MVC Controllers is not limited to only REST. The following Spring Web MVC Controller:

@Controller
public class SpringController {

	@GetMapping("/html")
	public String html(@RequestParam("name") String name, Model model) {
		model.addAttribute("name", name);
		return "simple";
	}
}

Provides the following web page:

<html><body><p th:text="'Hello ' + ${name}" /></body></html>

Testing

The following tests demonstrate the Spring Web MVC Controllers servicing requests.

	@RegisterExtension
	public static final MockWoofServerExtension server = new MockWoofServerExtension();

	@Test
	public void get() {
		MockWoofResponse response = server.send(MockWoofServer.mockRequest("/rest"));
		response.assertJson(200, new ResponseModel("GET Spring Dependency"));
	}

	@Test
	public void pathParam() {
		MockWoofResponse response = server.send(MockWoofServer.mockRequest("/rest/path/parameter"));
		response.assertJson(200, new ResponseModel("parameter"));
	}

	@Test
	public void post() {
		MockWoofResponse response = server
				.send(MockWoofServer.mockJsonRequest(HttpMethod.POST, "/rest/update", new RequestModel("INPUT")));
		response.assertJson(200, new ResponseModel("INPUT"));
	}

	@Test
	public void html() {
		MockWoofResponse response = server.send(MockWoofServer.mockRequest("/html?name=Daniel"));
		response.assertResponse(200, "<html><body><p >Hello Daniel</p></body></html>");
	}
