Проблема разработки через тестирование

2 голосов
/ 06 мая 2010

Я новичок в Java EE 6 и пытаюсь разработать очень простое приложение JAX-RS. RESTfull веб-сервис работает нормально. Однако когда я запустил свое тестовое приложение, я получил следующее. Что я сделал не так? Или я забыл любую конфигурацию? Конечно, я создаю JNDI и использую Netbeans 6.8 IDE. В заключение, спасибо за любые советы.

Моя сущность: 


@Entity
@Table(name = "BOOK")
@NamedQueries({
    @NamedQuery(name = "Book.findAll", query = "SELECT b FROM Book b"),
    @NamedQuery(name = "Book.findById", query = "SELECT b FROM Book b WHERE b.id = :id"),
    @NamedQuery(name = "Book.findByTitle", query = "SELECT b FROM Book b WHERE b.title = :title"),
    @NamedQuery(name = "Book.findByDescription", query = "SELECT b FROM Book b WHERE b.description = :description"),
    @NamedQuery(name = "Book.findByPrice", query = "SELECT b FROM Book b WHERE b.price = :price"),
    @NamedQuery(name = "Book.findByNumberofpage", query = "SELECT b FROM Book b WHERE b.numberofpage = :numberofpage")})
public class Book implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "ID")
    private Integer id;
    @Basic(optional = false)
    @Column(name = "TITLE")
    private String title;
    @Basic(optional = false)
    @Column(name = "DESCRIPTION")
    private String description;
    @Basic(optional = false)
    @Column(name = "PRICE")
    private double price;
    @Basic(optional = false)
    @Column(name = "NUMBEROFPAGE")
    private int numberofpage;

    public Book()
    {
    }

    public Book(Integer id)
    {
        this.id = id;
    }

    public Book(Integer id, String title, String description, double price, int numberofpage)
    {
        this.id = id;
        this.title = title;
        this.description = description;
        this.price = price;
        this.numberofpage = numberofpage;
    }

    public Integer getId()
    {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public int getNumberofpage() {
        return numberofpage;
    }

    public void setNumberofpage(int numberofpage) {
        this.numberofpage = numberofpage;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Book)) {
            return false;
        }
        Book other = (Book) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "com.entity.Book[id=" + id + "]";
    }
}

Мой тестовый класс Junit: 


public class BookTest
{

    private static EntityManager em;
    private static EntityManagerFactory emf;

    public BookTest()
    {

    }

    @BeforeClass
    public static void setUpClass() throws Exception
    {
        emf = Persistence.createEntityManagerFactory("E01R01PU");
        em = emf.createEntityManager();
    }

    @AfterClass
    public static void tearDownClass() throws Exception
    {
        em.close();
        emf.close();
    }

    @Test
    public void createBook()
    {
        Book book = new Book();
        book.setId(1);
        book.setDescription("Mastering the Behavior Driven Development with Ruby on Rails");
        book.setTitle("Mastering the BDD");
        book.setPrice(25.9f);
        book.setNumberofpage(1029);

        em.persist(book);

        assertNotNull("ID should not be null", book.getId());
    }
}

My persistence.xml 


<persistence>
  <persistence-unit name="E01R01PU" transaction-type="JTA">
    <jta-data-source>BookstoreJNDI</jta-data-source>
    <properties />
  </persistence-unit>
</persistence>

Во-первых, вам не хватает некоторых JAR-файлов на вашем пути к классам, и я предлагаю добавить $GF_HOME/modules/gf-client.jar (не копируйте JAR-файл в ваш проект, укажите прямо на него).

Во-вторых, ваш тест не пройдет в текущем состоянии, в нем отсутствуют некоторые части:

  • persist необходимо вызвать внутри транзакции
  • вам нужно flush внести изменения, чтобы получить присвоенный идентификатор.

Вот улучшенная версия, которая будет запускать каждый метод тестирования со своим собственным EntityManager и внутри транзакции (которая откатывается в конце метода тестирования): 

public class BookTest {
    private static EntityManager em;
    private static EntityManagerFactory emf;

    @BeforeClass
    public static void createEntityManagerFactory() {
        emf = Persistence.createEntityManagerFactory("E01R01PU");
    }

    @AfterClass
    public static void closeEntityManagerFactory() throws Exception {
        emf.close();
    }

    @Before
    public void beginTransaction() {
        em = emf.createEntityManager();
        em.getTransaction().begin();
    }

    @After
    public void rollbackTransaction() {
        if (em.getTransaction().isActive()) {
            em.getTransaction().rollback();
        }

        if (em.isOpen()) {
            em.close();
        }
    }

    @Test
    public void createBook() {
        Book book = new Book();
        book.setId(1);
        book.setDescription("Mastering the Behavior Driven Development with " +
                            "Ruby on Rails");
        book.setTitle("Mastering the BDD");
        book.setPrice(25.9f);
        book.setNumberofpage(1029);

        em.persist(book);
        em.flush(); // sync the in-memory changes with the db
        // now this will pass
        assertNotNull("ID should not be null", book.getId()); 
    }
}

Бонус: этот тест пройдёт:)

Обратите внимание, что люди обычно предпочитают иметь возможность запускать тесты без запуска контейнера, то есть без использования JNDI. Вот persistence.xml, показывающий, как настроить EclipseLink для подключения к базе данных Derby, работающей в режиме сервера, которую можно использовать в контексте тестирования:

У вас есть сначала «Причина: java.lang.ClassNotFoundException: com.sun.gjc.spi.ResourceAdapter "ошибка в выходных данных. Это должно быть первое, что вы должны исправить (чего-то не хватает). С другой стороны, я вижу так много аннотаций в вашем классе Book, которые в большинстве своем не нужны. В частности, для имен столбцов. Кстати: почему вы аннотируете атрибуты вместо получателей? Вы перезаписали equals (), но на самом деле не реализовали его (только для поля Id, а как насчет других полей?). И если вам нужно перезаписать equals, вы должны перезаписать hashCode а также. Позвольте IDE создавать их, это намного проще.
