Question

嗨，我遇到了上述框架集成的问题。

我在使用库版本的maven配置中使用JPA2：

Spring 3.0.5
Hibernate 3.5.4
Hibernate-jpa-2.0-api-1.0.0.Final

我正在使用persistence.xml：

<persistence-unit name="AccountingPU" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>com.westernacher.wps.bnotk.fibu.domain.BaseEntity</class>
        <class>com.westernacher.wps.bnotk.fibu.domain.AccountSettings</class>
        <!-- This is not any more necessary, it will be done in spring config.
        <properties>
            <property name="hibernate.ejb.cfgfile" value="/hibernate.cfg.xml"/>
        </properties> -->
    </persistence-unit>

和applicationContext.xml：

<context:annotation-config />
    <context:component-scan base-package="com.westernacher.wps.bnotk.fibu.dao" />
    <context:component-scan base-package="com.westernacher.wps.bnotk.fibu.service" />
<tx:annotation-driven transaction-manager="txManager" 
    proxy-target-class="false"
    mode="proxy" />

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    p:dataSource-ref="dataSource">
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
            <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
        </props>
    </property>
</bean>

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource"
    p:driverClassName="${dataSource.driverClassName}" p:url="${dataSource.url}"
    p:username="${dataSource.username}" p:password="${dataSource.password}" />

<context:property-placeholder location="classpath:datasource.properties" />

<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"
    p:entityManagerFactory-ref="entityManagerFactory" />

AccountSettingsDaoImpl类使用@Repository注释。此类中的数据库访问方法标有@Transactional：

@Transactional(readOnly=false)
    public void save(E entity) {
//      entityManager.merge(entity);
//      entityManager.flush();
        entityManager.persist(entity);
    }

Test类如下：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/applicationContext.xml")
public class AccountSettingsDaoImplTest {

    @Resource
    private AccountSettingsDaoImpl accountSettingsDaoImpl;

    private final static Long id=1L;

    @Test
    public void testSave() throws Exception {
        AccountSettings accountSettings = new AccountSettings();
        accountSettings.setCategory("A");
        accountSettings.setDescription("adlkjsadhad asdlkasdkjahsdlkashd ");
        accountSettingsDaoImpl.save(accountSettings);

        Long localId = accountSettings.getId();
        System.out.println("id="+localId);
    }
}

但是运行我的JUnit-Tests，我将得到以下异常：

29.07.2011 18:46:01 org.springframework.test.context.TestContextManager prepareTestInstance

任何人都可以帮助我吗？

最诚挚的问候，丹尼尔

您不能按具体类型注入代理（如果它们是由接口创建的） - 您应该使用该接口：

@Inject
private AccountSettingsDao accountSettingsDao;
