java - 为什么我得到 javax.ejb.EJBTransactionRolledbackException？ - setRollbackOnly

Question

在我的 Web 应用程序中，我在 Apache Tomcat (TomEE)/7.0.37 服务器上使用 OpenJPA。

我的实体 User.class:

@Entity
@Table(name = "USER")
public class User implements Serializable {
  private static final long serialVersionUID = 1L;
  @Id
  @GeneratedValue
  @Basic(optional = false)
  @Column(name = "id_user")
  private Integer idUser;
  @Size(max = 8)
  @Column(name = "login")
  private String login;
  @Size(max = 128)
  @Column(name = "password")
  private String password;
  @OneToOne(cascade = CascadeType.ALL, mappedBy = "user")
  private Lecturer lecturer;
  @OneToOne(cascade = CascadeType.ALL, mappedBy = "user")
  private Student student;
  @OneToMany(cascade = CascadeType.ALL, mappedBy = "user")
  private List<UserHasRoles> userHasRolesList;

  //constructors, getters, setters
}

当我创建新用户时:

    public void addUser(String log, String pass) {     
        User user = new User(); //utworzenie użytkownika i dodanie do bazy 
        user.setLogin(log);
        user.setPassword(pass);
        em.persist(user);
    }

我得到异常:

javax.el.ELException: javax.ejb.EJBTransactionRolledbackException: Transaction was rolled back, presumably because setRollbackOnly was called during a synchronization

Caused by:
org.apache.geronimo.transaction.manager.SetRollbackOnlyException - setRollbackOnly() called. See stacktrace for origin
at org.apache.geronimo.transaction.manager.TransactionImpl.setRollbackOnly(TransactionImpl.java:126)

我尝试更改生成 ID 策略，但没有帮助。 怎么了？

Answer 1

好吧，我发现我的错:

我得到这个异常是因为我在数据库中有 64 个字符 (CHAR(64)) 的密码字段，我试图在那里写 128 个字符的字符串。更改数据库中的表解决了我的问题。

因此，当您收到此异常时，请检查您的@Entity 类是否具有与您在数据库表中的类型相同的字段(具有相同的类型)。

谢谢大家的帮助。对于给您带来的麻烦和困惑，我深表歉意。
