Rest-Assured/JUnitはHTTPエラーコード400を返す

Question

私はSpringブートで単純なRESTを書いて、安心して書かれたテストケースは、カールからうまく動作する間にhttpコード400を返します。

サービス：

@RestController 
@RequestMapping("/customerService") 
public class CustomerService 
{ 
    private static final Logger logger = Logger.getLogger(CustomerService.class.getName()); 

    @RequestMapping(value = "/customers/{id}", 
     produces = { "application/hal+json", "application/json" }, 
     consumes = { "application/json" }, method = RequestMethod.GET) 
    public ResponseEntity<Customer> getCustomer(@PathVariable (value="id") String id) 
    { 
     logger.debug("getCustomer ["+id+"]"); 

     Customer customer = new Customer(); 
     ResponseEntity<Customer> response = ResponseEntity.ok(customer); 

     customer.id="10"; 
     customer.name="Foobar"; 
     customer.category="Elite"; 

     return response; 
    } 
} 

テストクラス：

public class TestCustomer 
{ 
    @Test 
    public void testStatus() throws IOException 
    { 
     String token = this.loadContentsFromFile("./src/test/resources/user-token.txt"); 
     String response = 
       given() 
       .header("Authorization",token).and().header("Accept","application/json") 
       .contentType("application/json") 
       .when() 
        .get("http://localhost:8080/customerService/customers/10") 
        .peek() // Use peek() to print the ouput 
        .asString(); 

     assertNotNull(response); 
     System.out.println("body : " +response); 
    } 
    public String loadContentsFromFile(String path) throws IOException 
    { 
     return new String(Files.readAllBytes(Paths.get(path))); 
    } 
} 

テストランナー：

public class TestSuite { 
    public static void main(String[] args) { 
     Result result = JUnitCore.runClasses(TestCustomerService.class); 

     for (Failure failure : result.getFailures()) { 
      System.out.println(failure.toString()); 
     } 

     System.out.println(result.wasSuccessful()); 
    } 
}

ここでは正常に動作カールリクエストです：

は - 受信応答

DEBUG org.apache.http.impl.conn.DefaultClientConnection：ライン後

は400を返すと言いますだから私は

は、ここで戻りコード200とカールレスポンスとボディです私は何が間違っているのか理解しようとしています。 1つのことは私がなぜ安心しているのかということを困惑させ、リクエストに 'Content-length：0'ヘッダーを追加することです。私は安心してJUnitのテストフレームワークを学習しています.GETリクエストを1つ取得しようとしています。どんな助けもありがとう。

いいえ何も試してみると解決策が見つかりました。明らかに、Files.readAllBytes（）はトークン値に改行を追加していました。そこで、loadContentsFromFileメソッドを、Scannerを使ってうまく動作したファイルを読み込むために置き換えました。

public String loadContentsFromFile(String path) throws IOException 
{ 
    Scanner scanner=null; 
    String text=""; 
    try 
    { 
     scanner= new Scanner(new File(path)); 
     text = scanner.next(); 
    } 
    finally 
    { 
     scanner.close(); 
    } 
    return text; 
    //  return new String (Files.readAllBytes(Paths.get(path)),Charset.defaultCharset()); 
    //has a bug it adds a line break at the end. 
} 

だから、この原因ヘッダー"Authorization: <token>"は、改行せずにサーバーに行き、それを呼び出します残りを働きました。

Files.readAllBytes（）がファイルに改行を付けていないのに改行を追加していたのはなぜか分かりません。
