Spring,Hibernate和JPA:在entitymanager上调用persist似乎没有提交到数据库

我正在尝试使用Hibernate和JPA设置Spring,但在尝试持久化对象时,似乎没有任何东西添加到数据库中.

使用以下内容:

在AccountManager中,我正在做:

@Repository
public class AccountManager implements IAccountManager {

    @PersistenceContext private EntityManager em;

    /* -- 8< -- Query methods omitted -- 8< -- */

    public Account storeAccount(Account ac) {
    ac = em.merge(ac);
        em.persist(ac);
        return ac;
    }
}

交流来自:

    Account ac = new Account();
    ac.setId(mostRecent.getId()+1);
    ac.setUser(user);
    ac.setName(accName);
    ac.setDate(new Date());
    ac.setValue(0);
    ac = accountManager.storeAccount(ac);
    return ac;

有没有人可以指出我做错了什么？持久调用返回而不抛出异常.如果之后我这样做em.contains(ac),则返回true.

如果有人需要,这里是如何定义帐户:

@SuppressWarnings("serial")
@Entity
@NamedQueries({
        @NamedQuery(name = "Account.AllAccounts", query = "SELECT a FROM Account a"),
        @NamedQuery(name = "Account.Accounts4User", query = "SELECT a FROM Account a WHERE user=:user"), 
        @NamedQuery(name = "Account.Account4Name", query = "SELECT a FROM Account a WHERE name=:name"),
        @NamedQuery(name = "Account.MaxId", query = "SELECT MAX(a.id) FROM Account a"),
        @NamedQuery(name = "Account.Account4Id", query = "SELECT a FROM Account a WHERE id=:id"),
    })
public class Account extends AbstractNamedDomain {
    @Temporal(TemporalType.DATE)
    @Column(name = "xdate")
    private Date date;

    private double value;

    @ManyToOne(cascade={CascadeType.PERSIST, CascadeType.MERGE})
    @JoinColumn(name="userid")
    private User user;

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    @OneToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE}, fetch=FetchType.EAGER)
    @OrderBy("date")
    private List accountActivity = new ArrayList();

    public List getAccountActivity() {
        return accountActivity;
    }

    public void setAccountActivity(List accountActivity) {
        this.accountActivity = accountActivity;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public double getValue() {
        return value;
    }

    public void setValue(double value) {
        this.value = value;
    }

    public void addAccountActivity(AccountActivity activity) {
        // Make sure ordering is maintained, JPA only does this on loading
        int i = 0;
        while (i < getAccountActivity().size()) {
            if (getAccountActivity().get(i).getDate().compareTo(activity.getDate()) <= 0)
                break;
            i++;
        }
        getAccountActivity().add(i, activity);
    }
}

@MappedSuperclass public abstract class AbstractNamedDomain extends AbstractDomain {

    private String name;

    public AbstractNamedDomain() {

    }

    public AbstractNamedDomain(String name) {

        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

@MappedSuperclass public abstract class AbstractDomain implements Serializable {

    @Id @GeneratedValue
    private long id = NEW_ID;

    public static long NEW_ID = -1;

    public long getId() {
        return id;
    }

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

    public boolean isNew() {

        return id==NEW_ID;
    }
}

感谢eric和Juan Manuel的回答,我能够弄清楚交易没有得到承诺.

将@Transactional添加到storeAccount方法就可以了!
