Java @TransactionConfiguration（transactionManager=“txManager”）NoSuchBeanDefinitionException:未定义名为“txManager”的bean

我试着写一个测试类，测试一个dao方法。dao方法在发送电子邮件后从jobseeker表中进行选择，并使用getCurrentSession，因此我的测试类如下所示

@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

当我有一个名为txManager的bean时，我不知道为什么会得到这个。任何帮助都会很好。

使用

---

如上所述。

您的XML配置将需要以下行：

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

这将启用基于注释的事务管理

如果您正在执行Java配置，Config类上的@EnableTransactionManagement注释也会执行相同的操作

编辑以获取更多信息

---

您还应该能够完全省略@TransactionConfiguration注释。有关更多详细信息，请参阅文档。您可能希望@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这样做

你能给我一个例子的链接吗？从这里我真的不明白。对不起，我忘了把这一行放在代码里，但我的dao里有它，我更正了now@FAndrew你还收到同样的问题吗？确保sprint-config.xml位于类路径上，以防它找不到xml文件。

        @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;
            }
        }
