未找到[javax.sql.DataSource]类型的符合条件的bean

我正在努力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 严重：允许TestExecutionListener[org.springframework.test.context.support]时捕获异常。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.CompanyDaoTest”的bean时出错：自动连线依赖项的注入失败；嵌套异常为org.springframework.beans.factory.BeanCreationException:无法自动连接方法：public void org.springframework.test.context.junit4.AbstractTransactionalJunit4SspringContextTests.setDataSource（javax.sql.DataSource）；嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException:未找到依赖项类型为[javax.sql.DataSource]的符合条件的bean：至少需要1个符合此依赖项autowire候选项条件的bean。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/>

这是公司测试类

@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");
    }

@RunWith（SpringJUnit4ClassRunner.class）
公共类CompanyDaoTest扩展了AbstractDaoForTesting{
上市公司daotest（）{}
/**
*CompanyDao实现的find（id）方法的测试用例
*@抛出异常
*/
@试验
public void testFind（）引发异常{
debug（“\n开始测试查找（）\n”）；
List allItems=companyDao.findAll（）；
assertTrue（allItems.size（）>0）；
//获取列表中的第一项
公司c1=allItems.get（0）；
int id=c1.getId（）；
公司c2=公司dao.find（id）；
资产真（c1.等于（c2））；
debug（“\n完成的testFind（）\n”）；
}

如有任何建议，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了Spring文档之后，我发现我遗漏了一些东西。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

    <context:annotation-config/>


    <bean id="propertyConfigurer"

我可以看com.russ.home.test.dao.CompanyDaoTest吗？
