无法加载ApplicationContext：在bean工厂中找不到持久性异常转换器

标签： java spring hibernate junit

我有一个抽象的测试用例，用于测试我的Spring MVC控制器：

@SuppressWarnings("unused")
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:META-INF/spring/applicationContext.xml",
                        "classpath:META-INF/spring/applicationContext-jpa.xml",
                        "file:src/main/webapp/WEB-INF/spring/webmvc-config-test.xml"}) 
@PersistenceContext(name = "persistenceUnit")
public class TestableControllerTest {

    @Autowired
    ApplicationContext applicationContext;

    private MockHttpServletRequest request;
    private MockHttpServletResponse response;   
    private RequestMappingHandlerAdapter handlerAdapter;

    @Before
    public void setUp() {
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();

        handlerAdapter = applicationContext.getBean(RequestMappingHandlerAdapter.class);
    }

    @Test
    public void testMethod() {

    }

    private Object getHandler(MockHttpServletRequest request) throws Exception {
        HandlerExecutionChain chain = null;  

        Map<String, HandlerMapping> map = applicationContext.getBeansOfType(HandlerMapping.class);  
        Iterator<HandlerMapping> itt = map.values().iterator();  

        while (itt.hasNext()) {  
            HandlerMapping mapping = itt.next();  
            chain = mapping.getHandler(request);  
            if (chain != null) {  
                break;  
            }   
        }  

        if (chain == null) {  
            throw new InvalidParameterException("Unable to find handler for request URI: " + request.getRequestURI());  
        }  

        return chain.getHandler();      
    }

}

运行 mvn clean surefire-report：report

结果：

这很奇怪，因为我的persistence.xml不仅配置了JPA方言：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
            <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
            <property name="hibernate.hbm2ddl.auto" value="create"/>
            <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
            <property name="hibernate.connection.charSet" value="UTF-8"/>
            <!-- Uncomment the following two properties for JBoss only -->
            <!-- property name="hibernate.validator.apply_to_ddl" value="false" /-->
            <!-- property name="hibernate.validator.autoregister_listeners" value="false" /-->
            <property name="hibernate.hbm2ddl.import_files" value="dynamic.sql, static.sql"/>
        </properties>
    </persistence-unit>
</persistence>

但我还在applicationContext-jpa.xml

中明确注册了一个异常翻译器 
<bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>

我不能为我的生活解决为什么bean工厂不提供这个实例。任何想法或建议表示赞赏。

任何类型的配置错误，例如spring xml文件中EMF工厂bean定义中的packagesToScan属性都可能抛出此错误 - 这个错误很容易。

答案 1 :(得分：0)

在pom.xml中添加'spring-tx'maven依赖项。如果在此依赖项的旧版本中运行，请升级到新版本。这样可以解决问题。
