在我的网络应用程序中，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);
}
我得到例外：
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)
我尝试改变生成ID策略，但它没有帮助。 有什么问题？

答案 0 :(得分：13)
好的，我发现了我的错：
我得到了这个例外，因为我在数据库中有64个字符的密码字段（CHAR（64）），我试图在那里写入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类是否具有与数据库表中的类型相同的字段（具有相同类型）。
谢谢大家的帮助。对于麻烦和困惑，我感到很抱歉。
