找不到[javax.sql.DataSource]类型的合格bean

Question

我很难理解为什么会发生这种错误。我正在将教程移植到最新版本的Spring、Hibernate和WildFly。我从命令行运行，使用Maven构建和测试应用程序。我得到以下错误：

2015年7月10日下午2:18:03 org.springframework.test.context。TestContextManager prepareTestInstance SEVERE:允许TestExecutionListener时捕获异常[org.springframework.test.context.support.DependencyInjectionTestExecutionListener@523884b2]准备测试实例[com.russ.home.test.dao.CompanyDaoTest@131774fe]org.springframework.beans.factory。BeanCreationException:创建名为“com.russ.home.test.dao的bean时出错。CompanyDaoTest：注入自动连接依赖项失败；嵌套异常是org.springframework.beans.factory。BeanCreationException:无法自动连线方法：public void org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests.setDataSource（javax.sql.DataSource）；嵌套异常是org.springframework.beans.factory。NoSuchBeanDefinitionException：未找到依赖项的类型为[javax.sql.DataSource]的合格bean：应至少有一个bean符合此依赖项的autowire候选。依赖项批注：{}

这是我的测试应用程序上下文文件：

<bean id="propertyConfigurer"
             class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
             p:location="classpath:jdbc.properties" />

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


       <bean id="jpaVendorAdapter"
             class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
             p:showSql="true"
             p:databasePlatform="org.hibernate.dialect.MySQLDialect" />

       <bean id="entityManagerFactory"
             class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
             p:persistenceUnitName="ttt-jpa"
             p:dataSource-ref="tttDataSource"
             p:jpaVendorAdapter-ref="jpaVendorAdapter"
             p:persistenceXmlLocation="classpath*:META-INF/test-persistence.xml"
               />

       <!-- Transaction manager for a single JPA EntityManagerFactory (alternative to JTA) -->
       <bean id="transactionManager"
             class="org.springframework.orm.jpa.JpaTransactionManager"
             p:dataSource-ref="tttDataSource"
             p:entityManagerFactory-ref="entityManagerFactory"/>

       <!-- checks for annotated configured beans -->
       <context:annotation-config/>

这是抽象测试类

@WebAppConfiguration
@ContextConfiguration
        ({
                "classpath*: /testingContext.xml",


        })
public abstract class AbstractDaoForTesting extends AbstractTransactionalJUnit4SpringContextTests {

    protected final Logger logger = LoggerFactory.getLogger(this.getClass());


    @Autowired(required = true)
    protected CompanyDao companyDao;
    @Autowired(required = true)
    protected ProjectDao projectDao;
    @Autowired(required = true)
    protected TaskDao taskDao;
    @Autowired(required = true)
    protected UserDao userDao;
    @Autowired(required = true)
    protected TaskLogDao taskLogDao;


}

这是CompanyDAOTest类。

@RunWith(SpringJUnit4ClassRunner.class)
public class CompanyDaoTest extends AbstractDaoForTesting {

    public CompanyDaoTest(){}

    /**
     * Test case for the find(id) method of the CompanyDao implementation
     * @throws Exception
     */
    @Test
    public void testFind() throws Exception {

        logger.debug("\nSTARTED testFind()\n");
        List<Company> allItems = companyDao.findAll();

        assertTrue(allItems.size() > 0);

        // get the first item in the list
        Company c1 = allItems.get(0);

        int id = c1.getId();

        Company c2 = companyDao.find(id);

        assertTrue(c1.equals(c2));
        logger.debug("\nFINISHED testFind()\n");
    }

任何建议将不胜感激。

在比较了其他应用程序上下文文件并重新阅读Spring留档后，我发现我缺少了几样东西。我重新开始并创建了这个新的应用程序上下文并移动了传递这个错误。

<!-- Activates various annotations to be detected in bean classes for ex @Autowired -->
