应用程序:Spring + Hibernate + Apache CXF - 想法简单说出问候服务,它在数据库中取一个param-id对象并返回文本“Hello:”+ person.getName();

以下是一些代码:

@Entity
public class Person {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id;

    private String login;

    private String email;
//getters and setters
}

的PersonDAO: 公共接口PersonDAO {     public void savePerson(Person person);     public Person getPerson(long id); }

PersonDAOImpl:

@Repository
@Transactional
public class PersonDAOImpl implements PersonDAO {

    @Autowired
    private SessionFactory sessionFactory;

    public void savePerson(Person person) {
        sessionFactory.getCurrentSession().save(person);
    }

    public Person getPerson(long id){
        Hibernate.initialize(sessionFactory);
        return (Person) sessionFactory.getCurrentSession().load(Person.class, id);
    }
}

PersonWebService:

@WebService
public interface PersonWebService {
    public String sayHello(long id);
}

PersonWebServiceImpl:

@WebService(endpointInterface="com.robert.example.testowy.webservices.PersonWebService")
public class PersonWebServiceImpl implements PersonWebService{

    @Autowired
    private PersonDAO personDAO;

    public String sayHello(long id) {
        Person person = personDAO.getPerson(id);
        return "Hello: " + person.getLogin();
    }

}

来自xml的数据源conf(dataSurce,sessionFactory):

<context:annotation-config />

    <context:component-scan base-package="com.robert.example.testowy" />


    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
        p:driverClassName="com.mysql.jdbc.Driver"
        p:url="jdbc:mysql://localhost:3306/edyplom"
        p:username="root"
        p:password="sedes" />

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan">
            <value>com.robert.example.testowy.domain</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
            </props>
        </property>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

我找到了一些解决方案,但它对我不起作用。我感谢任何帮助建议,当然还有解决方案。

好的,我得到了一个错误的地方...我的案例中的WebService方法sayHello,应该是事务性的......在添加注释@Transactional over sayHello后工作正常。
