未找到 [javax.sql.DataSource] 类型的合格 bean

Question

我正在努力理解为什么会发生此错误。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。我收到以下错误：

2015 年 7 月 10 日下午 2:18:03 org.springframework.test.context.TestContextManager prepareTestInstance 严重：在允许 TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@523884b2] 准备测试实例 [com.russ.home.test.dao.CompanyDaoTest@131774fe] 时捕获异常 org.springframework.beans.factory.BeanCreationException：创建名为“com.russ.home.test.dao.CompanyDaoTest”的bean时出错：注入自动装配的依赖项失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：无法自动装配方法：public void org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests.setDataSource(javax.sql.DataSource);嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型为 [javax.sql.DataSource] 的合格 bean：预计至少有 1 个 bean 有资格作为此依赖项的自动装配候选者。依赖注释：{}

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。

在比较其他应用程序上下文文件并重新阅读 Spring 文档后，我了解到我遗漏了几件事。我重新开始并创建了这个新的应用程序上下文并通过了这个错误。

<!-- Activates various annotations to be detected in bean classes for ex @Autowired -->
    <context:annotation-config/>


    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
