`src/main/java/djmil/cashcard/CashCardController.java`
|

|
||||
```java
|
||||
package example.cashcard;
|
||||
|
||||
import org.springframework.http.ResponseEntity;
|
||||
import org.springframework.web.bind.annotation.GetMapping;
|
||||
import org.springframework.web.bind.annotation.PathVariable;
|
||||
import org.springframework.web.bind.annotation.RequestMapping;
|
||||
import org.springframework.web.bind.annotation.RestController;
|
||||
|
||||
@RestController
|
||||
public class CashCardController {
|
||||
@GetMapping("/cashcards/{requestedId}")
|
||||
public ResponseEntity<CashCard> findById(@PathVariable Long requestedId) {
|
||||
if (requestedId.equals(99L)) {
|
||||
CashCard cashCard = new CashCard(99L, 123.45);
|
||||
return ResponseEntity.ok(cashCard);
|
||||
} else {
|
||||
return ResponseEntity.notFound().build();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
# @GetMapping
|
||||
|
||||
Needs the URI Path and tells Spring to route `GET` requests strictly to the `findById` method.
|
||||
|
||||
## Alternative variant for providing URI mapping for `@RestConttroller`
|
||||
|
||||
```java
|
||||
@RestController
|
||||
@RequestMapping("/cashcards")
|
||||
public class CashCardController {
|
||||
|
||||
@GetMapping("/{requestedId}")
|
||||
public ResponseEntity<String> findById() {
|
||||
```
|
||||
|
||||
# @PathVariable
|
||||
|
||||
Spring needs to know how to get the value of the `requestedId` parameter. This is done using the `@PathVariable` annotation. The fact that the parameter name matches the `{requestedId}` text *(URI Path)* within the `@GetMapping` parameter allows Spring to assign (inject) the correct value to the `requestedId` variable.
|
||||
|
||||
# ResponseEntity
|
||||
|
||||
REST says that the Response needs to contain a Cash Card in its body, and a Response code of 200 (OK). Spring Web provides the `ResponseEntity` class for this purpose. It also provides several utility methods to produce Response Entities. Here `ResponseEntity` used to create a Response with code **200 (OK)**, and a body containing a `CashCard`.
|
||||
|
||||
# Testing
|
||||
|
||||
Testing `GET` and other REST request is considerate to be [[IntegrationTests]].
|
||||
|
||||
Also, after running the application, you can use browser (or any other web-testing tool) by visiting http://localhost:8080/cashcards/99
