问题：
JBoss Seam+jsf javax.ejb.EJBTransactionRolledBackException“
颜昕
我对JSF很陌生，我先尝试了一个crud操作来继续我的项目，但是我在将数据插入到表中的时候遇到了一个问题。希望有人能对我的错误开刀。我从控制台上的错误报告开始，然后是类。
我的堆栈跟踪如下：

我用于插入日期的xhtml页面：
<ui:define name="main-container">
<div class="panel-content">
<h:form class="input-list" id="creatuser" style="width:100%;">
<h:panelGrid border="1" class="creatUserDetailsTable">
<f:facet name="header">
<h:outputText value="User Login History"
style="font-size: 23px; font-weight: bold; color: threeddarkshadow;" />
</f:facet>
<s:decorate id="nameDec" template="../../../secure/edit.xhtml">
<ui:define name="label">Name:</ui:define>
<h:inputText tabindex="1" id="amount" type="text"
class="miniusername clp"
value="#{loginhistoryAction.currentLoginhistory.name}" required="true">
<f:validateLength minimum="3" maximum="20" />
</h:inputText>
</s:decorate>
</h:panelGrid>
<h:commandButton value="Save" tabindex="20" class="usersubmit"
action="#{loginhistoryAction.create}">
</h:commandButton>
</h:form>
<h:messages globalOnly="true" />
</div>
</ui:define>
使用的接口:@Local public Interface LoginhistoryAction extends Serializable{public String create（）；public String initCurrentLoginhistory（）；public void setCurrentLoginhistory（Loginhistory currentLoginhistory）；public Loginhistory getCurrentLoginhistory（）；}
action类实现了上述接口:@Name（“LoginhistoryAction”）@Stateless@AutoCreate公共类LoginhistoryActionImpl实现了LoginhistoryAction{@Out（值=“CurrentLoginHistory”,scope=ScopeType.Conversation)@In（值=“CurrentLoginHistory”,scope=ScopeType.Conversation,required=false）private Loginhistory CurrentLoginHistory；
public Loginhistory getCurrentLoginhistory() {
return currentLoginhistory;
}
public void setCurrentLoginhistory(Loginhistory currentLoginhistory) {
this.currentLoginhistory = currentLoginhistory;
}
@In
private LoginhistoryService LoginhistoryService;
private static final long serialVersionUID = 8282995226262125676L;
public String create() {
currentLoginhistory.setRef("Test");
Integer id = LoginhistoryService.saveOrUpdate(this.currentLoginhistory);
return "/secure/userhome.xhtml";
}
@Override
public String initCurrentLoginhistory() {
currentLoginhistory = new Loginhistory();
return "/secure/common/history/loginHistory.xhtml";
}
}
服务接口:@local public interface LoginhistoryService extends Serializable{public abstract Integer saveOrUpdate（Loginhistory Loginhistory）；}
ServiceImpl类：
@Name("LoginhistoryService")
@Stateless
@AutoCreate
public class LoginhistoryServiceImpl implements LoginhistoryService {
private static final long serialVersionUID = 1L;
@In
private LoginhistoryDAO loginhistoryDAO;
public LoginhistoryServiceImpl() {
super();
}
@Override
// TODO what to do with lastmodified if it is modify
public Integer saveOrUpdate(Loginhistory loginhistory) {
LoginhistoryEntity loginhistoryEntity = LoginhistoryMapper.mapLoginhistoryEntity(loginhistory);
Integer loginhistoryId = loginhistoryDAO.saveOrUpdate(loginhistoryEntity);
return loginhistoryId;
}
}
映射器类：公共类LoginhistoryMapper{
public static LoginhistoryEntity mapLoginhistoryEntity(
Loginhistory loginhistory) {
LoginhistoryEntity loginhistoryEntity = new LoginhistoryEntity();
loginhistoryEntity.setId(loginhistory.getId());
loginhistoryEntity.setName(loginhistory.getName());
loginhistoryEntity.setDate(loginhistory.getDate());
return loginhistoryEntity;
}
}
@Name("loginhistoryDAO")
@Stateless
@AutoCreate
public class JPALoginhistoryDaoImpl implements LoginhistoryDAO {
private static final long serialVersionUID = -6173881454668735683L;
@PersistenceContext(unitName = "clrp")
private EntityManager entityManager;
Logger logger = Logger.getLogger(this.getClass());
public void setEntityManager(EntityManager em) {
this.entityManager = em;
}
@Override
public Integer saveOrUpdate(LoginhistoryEntity newLoginhistory) {
entityManager.merge(newLoginhistory);
return newLoginhistory.getId();
}
}
我的实体如下：
@Entity
@Table(name="loginhistory")
@NamedQueries(value = {
@NamedQuery(name = LoginhistoryEntity.fetchAll, query = "FROM LoginhistoryEntity" )})
public class LoginhistoryEntity implements Serializable {
private static final long serialVersionUID = 1L;
public final static String fetchAll = "LoginhistoryEntity.fetchAll";
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", updatable = false)
private int id;
@Column(name = "Date")
private Date date;
@Column(name = "Name")
private String name;
@Column(name = "Ref")
private String ref;
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public void setDate(Date date) {
this.date = date;
}
public Date getDate() {
return date;
}
public void setRef(String ref) {
this.ref = ref;
}
public String getRef() {
return ref;
}
}

最后，我发现了错误，一个微不足道的错误，对不起你在这里的时间…
我的实体以前是
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "historyId", updatable = false)
private Integer historyId;
这里的问题是整数类型，它应该是
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", updatable = false)
private Integer id;
干杯
