[解決済み】Spring boot - リクエストメソッド'POST'はサポートされていません。すべて試した

質問内容

Spring BootとMongoDBを使用して、従業員ドキュメントのCRUD操作を実行するだけのWebアプリケーションを構築しています。

次のようなエラーが発生します。 "Request method 'POST' not supported" jsonを使用してcreate employee endpointをヒットしようとしたとき。

私のコントローラクラスは

@RestController
@RequestMapping("/employeeapp/employees")
public class EmployeeController {

    private final EmployeeService service;

    @Autowired
    public EmployeeController(EmployeeService service) {
        this.service = service;
    }

    @RequestMapping(method = RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    public
    @ResponseBody
    Employee create(@RequestBody @Valid Employee employeeEntry) {
        return service.create(employeeEntry);
    }

    @RequestMapping(value = "{id}", method = RequestMethod.DELETE)
    public Employee delete(@PathVariable("id") long id) {
        return service.delete(id);
    }

    @RequestMapping(method = RequestMethod.GET)
    public List<Employee> findAll() {
        return service.findAll();
    }

    @RequestMapping(value = "{id}", method = RequestMethod.GET)
    public Employee findById(@PathVariable("id") long id) {
        return service.findById(id);
    }

    @RequestMapping(value = "{id}", method = RequestMethod.PUT)
    public Employee update(@RequestBody @Valid Employee employeeEntry) {
        return service.update(employeeEntry);
    }

    @ExceptionHandler
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public void handleEmployeeNotFound(EmployeeNotFoundException exception) {
    }

}

アプリケーションクラスです。

@SpringBootApplication
public class Application {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

を無効にしてみました。 csrf を追加し @ResponseBody をメソッドに追加しましたが、何も動作しないようです。

EDIT

を打っています。 http://localhost:8080/employeeapp/employees を POST リクエストで送信します。ヘッダには Content-Type : application/json で、ボディにこのようなjsonがあります。

{
    "id" : 1,
    "name" : "nikhil",
    "dept" : "DCX"
}

また、上記のURLをPOSTリクエストで叩いたときのログはこんな感じです。

2016-02-19 12:21:36.549  INFO 5148 --- [nio-8080-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/]       :

EDIT 2:

Spring bootのログを確認したところ、マッピングが生成されておらず、代わりにspringがデフォルトのサービスにマッピングしていることが判明しました。なぜこのようなことが起こるのか、何か思い当たることはありますか？

解決方法は？

以下が参考になると思います。

1. アプリケーションをデプロイしている間、spring bootはすべての コンソールに利用可能なサービスが表示されます。を作成するためのPOSTメソッドを確認します。 が表示されているかどうか。他のサービスと矛盾がないことを確認する。GET/PUT/POST
2. デプロイされていないサービスがある場合は、他のサービス（GET、PUT、POST）の前に'/'を追加してみてください。
3. 例外ハンドラの追加( リンク ) を使用して、クライアントの入力要求をチェックして、POJO 構造をチェックします。
4. URLの確認 - app/nameのグローバルパスがある場合 を設定する必要があります( リンク )
5. リクエストヘッダのContent-Typeを削除して投稿してみてください。 再度リクエスト

以下は、起こりうるさまざまな事柄です。順番に追っていく必要はありません。

EDIT

以下を実行して、コントローラが有効になっているか、springアプリケーションで考慮されているかどうかを確認します。

import java.util.Arrays;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);

        System.out.println("Let's inspect the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            System.out.println(beanName);
        }
    }

    }
