我測試我的Spring MVC控制器創建了一個抽象測試用例：無法加載的ApplicationContext：沒有在bean工廠找到持久性的異常轉化
@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();
}
}
運行MVN清潔神火報告：報告
結果：

這是奇怪的，因爲不僅我的persistence.xml配置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>
但我也明確地註冊的applicationContext-jpa.xml異常翻譯
<bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>
我不能爲我的生活工作爲什麼bean工廠不提供此實例。任何想法或建議表示讚賞。
