Spring Download the complete REST CRUD example

Question

Does anyone have a complete REST CRUD boot example for spring boot? Spring.io only has RequestMapping for GET. I can make POST and DELETE work, but not PUT.

I suspect that I am trying to get the parameters where it is disabled, but I have not seen an example when someone is performing an update.

I am currently using the SO iPhone app, so I cannot insert my current code. Any working examples would be great!

Answer 1

As you can see, I implemented two methods of updating. The first will get json, and the second will get cusotmerId in the URL and json as well.

@RestController @RequestMapping("/customer") public class CustomerController { @RequestMapping(value = "/{id}", method = RequestMethod.GET) public Customer greetings(@PathVariable("id") Long id) { Customer customer = new Customer(); customer.setName("Eddu"); customer.setLastname("Melendez"); return customer; } @RequestMapping(value = "/", method = RequestMethod.GET) public List<Customer> list() { return Collections.emptyList(); } @RequestMapping(method = RequestMethod.POST) public void add(@RequestBody Customer customer) { } @RequestMapping(method = RequestMethod.PUT) public void update(@RequestBody Customer customer) { } @RequestMapping(value = "/{id}", method = RequestMethod.PUT) public void updateById(@PathVariable("id") Long id, @RequestBody Customer customer) { } @RequestMapping(value = "/{id}", method = RequestMethod.DELETE) public void delete() { } class Customer implements Serializable { private String name; private String lastname; public String getName() { return name; } public void setName(String name) { this.name = name; } public void setLastname(String lastname) { this.lastname = lastname; } public String getLastname() { return lastname; } } } 

Answer 2

Or alternatively:

 @RepositoryRestResource public interface CustomerRepository extends JpaRepository<Customer, Long> { } 

To use the org.springframework.data.rest.core.annotation.RepositoryRestResource annotation, you need to add the following dependency to your pom.xml:

 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-rest</artifactId> </dependency>

An alternative update returns a ResponseEntity object.

 @RestController @RequestMapping("/fruits") public class FruitController { private final Logger LOG = LoggerFactory.getLogger(FruitController.class); @Autowired private FruitService fruitService; @RequestMapping(method = RequestMethod.GET) public ResponseEntity<List<Fruit>> getAll(@RequestParam(value = "offset", defaultValue = "0") int index, @RequestParam(value = "numberOfRecord", defaultValue = "10") int numberOfRecord) { LOG.info("Getting all fruits with index: {}, and count: {}", index, numberOfRecord); List<Fruit> fruits = fruitService.getAll(index, numberOfRecord); if (fruits == null || fruits.isEmpty()) { return new ResponseEntity<List<Fruit>>(HttpStatus.NO_CONTENT); } return new ResponseEntity<List<Fruit>>(fruits, HttpStatus.OK); } @RequestMapping(value = "{id}", method = RequestMethod.GET) public ResponseEntity<Fruit> get(@PathVariable("id") int id) { LOG.info("Getting fruit with id: {}", id); Fruit fruit = fruitService.findById(id); if (fruit == null) { return new ResponseEntity<Fruit>(HttpStatus.NOT_FOUND); } return new ResponseEntity<Fruit>(fruit, HttpStatus.OK); } @RequestMapping(method = RequestMethod.POST) public ResponseEntity<Void> create(@RequestBody Fruit fruit, UriComponentsBuilder ucBuilder) { LOG.info("Creating fruit: {}", fruit); if (fruitService.exists(fruit)) { return new ResponseEntity<Void>(HttpStatus.CONFLICT); } fruitService.create(fruit); HttpHeaders headers = new HttpHeaders(); headers.setLocation(ucBuilder.path("/fruit/{id}").buildAndExpand(fruit.getId()).toUri()); return new ResponseEntity<Void>(headers, HttpStatus.CREATED); } @RequestMapping(value = "{id}", method = RequestMethod.PUT) public ResponseEntity<Fruit> update(@PathVariable int id, @RequestBody Fruit fruit) { LOG.info("Updating fruit: {}", fruit); Fruit currentFruit = fruitService.findById(id); if (currentFruit == null) { return new ResponseEntity<Fruit>(HttpStatus.NOT_FOUND); } currentFruit.setId(fruit.getId()); currentFruit.setName(fruit.getName()); fruitService.update(fruit); return new ResponseEntity<Fruit>(currentFruit, HttpStatus.OK); } @RequestMapping(value = "{id}", method = RequestMethod.DELETE) public ResponseEntity<Void> delete(@PathVariable("id") int id) { LOG.info("Deleting fruit with id: {}", id); Fruit fruit = fruitService.findById(id); if (fruit == null) { return new ResponseEntity<Void>(HttpStatus.NOT_FOUND); } fruitService.delete(id); return new ResponseEntity<Void>(HttpStatus.OK); } }
