java - @TransactionConfiguration(transactionManager ="txManager")NoSuchBeanDefinitionException : No bean named 'txManager' is defined

Question

我尝试编写一个测试类，测试dao方法。 dao 方法是在电子邮件之后从 jobseeker 表中进行选择，并且它使用 getCurrentSession，因此我使我的测试类像这样

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations="classpath:spring-config.xml") 
@TransactionConfiguration(transactionManager="txManager")
@Transactional
public class JobSeekerServiceTest {

    private JobSeekerDao jobseekerServiece = new JobSeekerDao();

    @Test
    public void testGetCandidateForEmail(){
        JobSeeker result = new JobSeeker();
        JobSeeker expected = new JobSeeker();
        expected.setName("Dummy Job seeker 1");expected.setEmail("email@yahoo.com");expected.setCity("City");expected.setPhone("04523122");

        result = jobseekerServiece.getCandidateForEmail("email@yahoo.com");
        assertEquals(result, expected);
    }
}

spring-config.xml

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">  
            <property name="driverClassName"    value="${database.driver}" />

            <property name="username"           value="${database.user}" />  
            <property name="password"           value="${database.password}" />  
        </bean>  

        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">  
            <property name="dataSource" ref="dataSource" />
            <property name="packagesToScan" value="com.awinta.hrms"/>

            <property name="hibernateProperties">

                    <prop key="hibernate.dialect">${hibernate.dialect}</prop>

                    <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

                    <prop key="hibernate.temp.use_jdbc_metadata_defaults">${hibernate.temp.use_jdbc_metadata_defaults}</prop>

                    <prop key="hibernate.connection.pool_size">${hibernate.connection.pool_size}</prop>
                </props>  
            </property>  
        </bean> 

        <bean id="txManager" 
            class="org.springframework.orm.hibernate4.HibernateTransactionManager" 
            name="txManager">  
            <property name="sessionFactory" ref="sessionFactory" />
        </bean> 

        <tx:annotation-driven transaction-manager="txManager"/> 

道方法

@SuppressWarnings("unchecked")
        @Override
        public JobSeeker getCandidateForEmail(String email) {
            LOGGER.debug("Searching the candidate after an email:"+email);
            Session session = getCurrentSession();

            List<JobSeeker> candidates = session.createQuery("from JobSeeker where email=?")
                    .setParameter(0, email)
                    .list();


            if (candidates.size() > 0) {
                return candidates.get(0);
            } else {
                return null;
            }
        }

我不知道为什么当我有一个名为 txManager 的 bean 时会得到这个信息。任何帮助都会很棒。

Answer 1

您的 XML 配置将需要这一行:

<tx:annotation-driven transaction-manager="txManager"/>

这可以实现基于注释的事务管理。

如果您正在执行 Java Config，则配置类上的 @EnableTransactionManagement 注释会执行相同的操作。

编辑以获取更多信息

您还应该能够完全省略 @TransactionConfiguration 注释。请参阅文档了解更多详细信息。您可能需要 @TransactionalConfiguration 的唯一原因是覆盖默认回滚配置，而您在上面的示例中没有执行此操作。 http://docs.spring.io/spring/docs/3.0.x/spring-framework-reference/html/testing.html#testcontext-tx
