Question

当我尝试在junit测试类中加载配置文件时，我在注入数据源时遇到错误：

似乎你无法访问“transactionManager”。正如我所看到的那样，你进行单元测试然后我想你不会访问ApplicationContext.xml文件（或者你的bean声明的地方）。

对于单元测试，您应该通过注释明确地提供bean文件。

这些注释对我有用：

@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=true)
@Transactional
@ContextConfiguration(locations={"classpath:applicationContext.xml",
    "classpath:applicationContext-dao.xml",
    "classpath:applicationContext-services.xml",
    "classpath:/com/xxx/zzz/test/CompanyServiceTest-context.xml"})
public class CompanyServiceTest extends AbstractTransactionalJUnit4SpringContextTests {
private static Log LOG = LogFactory.getLog(CompanyServiceTest.class);

@Autowired
public CompanyService companyService;

@Before
public void setUp() {
    System.err.println("Clear the mailboxes...");
    Mailbox.clearAll();
}

    @Test
    public void testCreateCompany() throws IOException, BusinessException, MessagingException {
        LOG.info("Creating the company DEMO...");
    }

}
