JAX-RSとMySqlデータベース（JPA）を使用してAPIを構築しています。JPAが返すオブジェクトが内部サーバエラーを返す
public Customer validateCustomer(Customer customer) {
//get the customer from the database
Query q = em.createQuery("SELECT c from Customer c WHERE c.login = :username");
q.setParameter("username", customer.getLogin());
List<Customer> results = q.getResultList();
//check if user exsists
if(!results.isEmpty()){
Customer fromDb = results.get(0);
//check if user provided correct password
if (!fromDb.getPassword().equals(customer.getPassword())) {
return null;
} else {
//create the session token and save it to the database
Random random = new SecureRandom();
String token = new BigInteger(130, random).toString(32);
tx.begin();
int executeUpdate = em.createQuery("UPDATE Customer c SET c.token = :token WHERE c.id = :id")
.setParameter("token", token)
.setParameter("id", fromDb.getId())
.executeUpdate();
tx.commit();
em.close();
//update previously pulled customer with the token
fromDb.setToken(token);
//return the customer
return fromDb;
}
} else {
return null;
}
}
このメソッドはによって呼び出されて消費されています：私の問題は、たび正しいログインがあるということである
public Response login (Customer customer){
Customer c = customerService.validateCustomer(customer);
if (c != null){
return Response.status(Response.Status.OK).entity(c).build();
//System.out.println(c);
} else {
return Response.status(Response.Status.FORBIDDEN).entity("Incorrect username or password.").build();
}
}
私は、ユーザー名とパスワードを検証し、セッションのためのトークンを作成している方法を以下している 提供され、私は私を戻しています
返品から;
私は私のブラウザで内部サーバーエラー500を取得しています：/ API /ユーザー/ログインをアクセスする
HTTPエラー500
問題。理由：
内部サーバーエラー桟橋を搭載
：私は、データベースから、元の顧客を返すいたときに//
しかしエラーのみocures。データベースから返された同じオブジェクトから新しいCustomerオブジェクトを構築して返しても、正常に動作しています。
Customer c = new Customer();
c.setEmail(fromDb.getEmail());
c.setLogin(fromDb.getLogin());
c.setToken(token);
c.setId(fromDb.getId());
Dbの代わりにcを返すと問題はありません。
データベースのオブジェクトが、作成されたオブジェクトと異なる結果を返す理由はありますか？

あなたのApp Server用にサーバー側のログが有効になっていますか？そこにスタックトレースを投稿できますか？ –
上記の理由が、データベースから取得したオブジェクトがJSONとしてmy $ .ajaxによって認識されないということができるのであれば、私は考えています。私の理解から、顧客クラスの "@XmlRootElement"は、顧客をXMLに変換し、同じ時間JSONを処理する責任があります。データベースから受け取ったオブジェクトが同じルートを経由していないため、 "@XmlRootElement"が存在しません私のオブジェクトに適用されます。それは可能ですか、もしそうなら、新しいオブジェクトを作成したり、すべての属性を1つから別のものに適用したりせずに、これをどのようにして動作させるか考えていますか？ – kazzzhc
