java - 无法注入资源 - 很可能是不正确的 InjectionServices SPI 实现 CDI

Question

我正在关注有关 Java EE 的复数教程之一。但是我在使用 Arquillian 测试我的应用程序时遇到了问题。Mayble github 将提供更多帮助（https://github.com/NoWishGranted/personal）当我使用 eclipse 运行测试用例时，我得到以下堆栈：

Jul 15, 2018 2:30:01 PM org.jboss.weld.bootstrap.WeldStartup <clinit>
INFO: WELD-000900: 2.3.5 (Final)
Jul 15, 2018 2:30:02 PM org.jboss.weld.injection.AbstractResourceInjection getResourceReference
WARN: WELD-000834: Unable to inject resource - most probably incorrect InjectionServices SPI implementation: private javax.persistence.EntityManager com.personal.bookstore.repository.BookRepository.em
    at com.personal.bookstore.repository.BookRepository.em(BookRepository.java:0)

我怀疑我的persistence.xml 文件可能有一些错误，但我不知道这是不是真的。（我正在使用wildfly和h2数据库）

持久性.xml

<?xml version="1.0" encoding="UTF-8"?>

    <persistence-unit name="bookStorePU" transaction-type="JTA">
        <properties>
            <property

                value="drop-and-create" />
            <property

            <property
                name="javax.persistence.schema-generation.scripts.drop-target"
                value="bookStoreDrop.ddl" />
        </properties>
    </persistence-unit>
</persistence> 

书本模型，没有所有可能的映射：

@Entity
public class Book {

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(length=200)
    private String title;

    @Column(length=200)
    private String description;

    @Column(name="unit_cost")
    private Float unitCost;

    private String isbn;

    @Column(name="publication_date")
    @Temporal(TemporalType.DATE)
    private Date publicationDate;

    @Column(name="number_of_pages")
    private Integer numberOfPages;

    private String imageUrl;

    private Language language;


    public Book(){
    }

    public Long getId() {
        return id;
    }

    public void setId(Long 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 Float getUnitCost() {
        return unitCost;
    }

    public void setUnitCost(Float unitCost) {
        this.unitCost = unitCost;
    }

    public String getIsbn() {
        return isbn;
    }

    public void setIsbn(String isbn) {
        this.isbn = isbn;
    }

    public Date getPublicationDate() {
        return publicationDate;
    }

    public void setPublicationDate(Date publicationDate) {
        this.publicationDate = publicationDate;
    }

    public Integer getNumberOfPages() {
        return numberOfPages;
    }

    public void setNumberOfPages(Integer numberOfPages) {
        this.numberOfPages = numberOfPages;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }

    public Language getLanguage() {
        return language;
    }

    public void setLanguage(Language language) {
        this.language = language;
    }

    @Override
    public String toString() {
        return "Book [id=" + id + ", title=" + title + ", description=" + description + ", unitCost=" + unitCost
                + ", isbn=" + isbn + ", publicationDate=" + publicationDate + ", numberOfPages=" + numberOfPages
                + ", imageUrl=" + imageUrl + ", language=" + language + "]";
    }
}

BookRepository 类

public class BookRepository {

    @PersistenceContext(unitName="bookStorePU")
    private EntityManager em;

    public Book find(Long id) {
        return em.find(Book.class, id);
    }

    @Transactional(TxType.REQUIRED)
    public Book create(Book book) {
        em.persist(book);
        return book;
    }

    @Transactional(TxType.REQUIRED)
    public void delete(Long id) {
        em.remove(em.getReference(Book.class, id));
    }

    public List<Book> findAll(){
        TypedQuery<Book> createQuery = em.createQuery("SELECT b from Book b order by b.title", Book.class);
        return createQuery.getResultList();
    }

    public Long countAll() {
        TypedQuery<Long> createQuery = em.createQuery("SELECT count(b) from Book b", Long.class);
        return createQuery.getSingleResult();
    }
}

测试用例类

@RunWith(Arquillian.class)
public class BookRepositoryTest {

    @Inject
    private BookRepository bookRepository;

    @Test
    public void create() {
        assertEquals(Long.valueOf(0), bookRepository.countAll());
        assertEquals(Long.valueOf(0), bookRepository.findAll());
    }

    @Deployment
    public static JavaArchive createDeployment() {
        return ShrinkWrap.create(JavaArchive.class)
                .addClass(BookRepository.class)
                .addClass(Book.class)
                .addClass(Language.class)
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }

}
