我想寫一個web服務來存儲一些數據使用jBoss 4.2.3和Oracle。
我想在CMT中使用Hibernate，並且在我看來它並沒有提交事務。 我有以下代碼：
豆：休眠不提交數據
@Stateless
@TransactionManagement(TransactionManagementType.CONTAINER)
public class ZzzBean implements ZzzI {
public ZzzBean() {
}
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public int addZzz() {
try {
Zzz z = new Zzz();
z.setA("a");
z.setI(new BigDecimal(11));
HibernateUtil.getSessionFactory().getCurrentSession().save(z);
} catch (Exception ex) {
ex.printStackTrace();
}
return 1;
}
}
接口：
@Local
public interface ZzzI {
int addZzz();
}
我會話工廠類：
public class HibernateUtil {
private static SessionFactory sessionFactory;
private static Configuration configuration;
static {
try {
configuration = new AnnotationConfiguration().configure();
sessionFactory = configuration.buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
的hibernate.cfg.xml有以下：
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@//my_host</property>
<property name="hibernate.connection.username">my_user</property>
<property name="hibernate.connection.password">my_pass</property>
<property name="show_sql">true</property>
<property name="current_session_context_class">jta</property>
<property name="transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
<property name="transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
<mapping resource="com/example/Zzz.hbm.xml" />
</session-factory>
映射文件：
<hibernate-mapping>
<class name="com.example.Zzz" table="ZZZ">
<id name="i" type="big_decimal">
<column name="i" precision="22" scale="0" />
<generator class="assigned" />
</id>
<property name="a" type="string">
<column name="a" length="20" />
</property>
</class>
</hibernate-mapping>
實體類：
@Entity
@Table(name = "ZZZ")
public class Zzz implements Serializable {
private static final long serialVersionUID = -4165930294512113400L;
private BigDecimal i;
private String a;
public Zzz(){}
@Id
@Column(name = "i", unique = true, nullable = false, precision = 22, scale = 0)
public BigDecimal getI() {
return this.i;
}
@Column(name = "a", length = 20)
public String getA() {
return this.a;
}
public void setI(BigDecimal i) {
this.i = i;
}
public void setA(String a) {
this.a = a;
}
}
而且Web服務代碼：
@WebService(name = "Zzz", serviceName = "Zzz")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
@Stateless
public class ZzzWS {
@EJB(beanName = "ZzzBean")
ZzzI z;
@WebMethod
public int addZzz() {
return z.addVisit();
}
}
當我調用Web服務方法，我有以下的輸出：

但是數據庫沒有，即使我停止JBoss的一個新紀錄。我的錯在哪裏？請幫忙。
P.S.當我不使用CMT並編寫代碼時：
tx = session.beginTransaction();
session.persist(...);
tx.commit();
所有工作正常。
