Question

尝试在我的Spring应用程序中对Dao运行单元测试我收到错误：命名查询未知。实际上我试图用spring 4.2实现缓存。

以下是与集成相关的代码：看看我的测试用例。

我的考试类： QuestionDaoTest

 public class QuestionDaoTest extends BaseDaoTest {

 @Autowired
 private QuestionTypeDao questionTypeDaoImpl;

 private static final Logger logger =LogManager.getLogger(QuestionDaoTest.class);

  @Test
  @Transactional
  public void test() {
  QuestionType questionType = 
    questionTypeDaoImpl.getQuestionTypeIdByName("Single Choice");
    logger.debug("Firing Query");
  }
}

我得到的错误

堆栈跟踪：

  org.springframework.orm.hibernate4.HibernateSystemException: Named query not known: getQuestionTypeIdByName;
  nested exception is org.hibernate.MappingException: Named query not known: getQuestionTypeIdByName at org.springframework.orm.hibernate4
  .SessionFactoryUtils.convertHibernateAccessException
  (SessionFactoryUtils.java:218)at org.springframework.orm.hibernate4
  .HibernateExceptionTranslator.convertHibernateAccessException
  (HibernateExceptionTranslator.java:57)

我的 dao-context-config.xml 定义：

<context:component-scan base-package="com.oea.dao" />
<cache:annotation-driven />
<tx:annotation-driven transaction-manager="transactionManager" />

 <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" 
     p:cacheManager-ref="ehcache"/>

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" 
     p:configLocation="classpath:ehcache.xml"  
     p:shared="true"/>

和我的DaoImpl： QuestionTypeDaoImpl

 @Repository
 public class QuestionTypeDaoImpl extends AbstractDao implements 
 QuestionTypeDao {

   @Cacheable("person")
   @Override
   public QuestionType getQuestionTypeIdByName(String questionType) {
     Query query = getSession().getNamedQuery("getQuestionTypeIdByName");
     query.setString("questionType", questionType);
     List<QuestionType> questionTypesId = query.list();
        logger.debug("Question Type name  " + questionTypesId + " in database..");

    }
    return questionTypesId.get(0);
}

我的Pojo： QuestionType

 @NamedQueries({ @NamedQuery(name = "getQuestionTypeIdByName", query = "from 
 QuestionType qt where qt.questionType = :questionType ") })

 @Entity
 @Table(name = "question_type")
 public class QuestionType {}

我认为有一个有效的ehcache.xml ... 我的 ehcache.xml 定义：

 <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<!-- <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
<cache name="employee" maxElementsInMemory="10000" eternal="true" overflowToDisk="false" /> -->
<diskStore path="java.io.tmpdir"/>
<cache name="person"
       maxElementsInMemory="100"
       eternal="false"
       timeToIdleSeconds="120"
       timeToLiveSeconds="120"
       overflowToDisk="true"
       maxElementsOnDisk="10000000"
       diskPersistent="false"
       diskExpiryThreadIntervalSeconds="120"
       memoryStoreEvictionPolicy="LRU"/>

我的junit控制台有以下内容：

有没有人知道我做错了什么？这似乎是一个非常直接的实现，正在处理我已经看到的所有教程，因为某些原因我无法在执行测试时启动应用程序。任何帮助将不胜感激。谢谢。
