春季單元測試JSR-303驗證

Question

我想在JSR-303驗證的春天爲註釋bean添加一個單元測試。

的bean是一個簡單的像這樣：

public class Bean { 
    @Size(max=XX) 
    String text; 
} 

在Spring配置我有所有必要的JAR文件：

：

validation-api 
hibernate-validator 

驗證程序是使用初始化

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> 

我的測試用例看起來像這樣（去除了彈簧和其他絨毛）：

@Autowired 
private LocalValidatorFactoryBean factory; 


@Test 
public void testTemplateFormBeanValidation() { 
// TODO exception at the moment. Can not resolve the validator. Provider issue. 
factory.setProviderClass(HibernateValidator.class); 
factory.setTraversableResolver(new DefaultTraversableResolver()); 
Validator val = factory.getValidator(); 
TemplateFormBean fb1 = new TemplateFormBean(); 
fb1.setText("this text works"); 
Set<ConstraintViolation<TemplateFormBean>> constraints = val.validate(fb1); 
assertNull(constraints); 

} 

當我運行這個測試，我得到以下堆棧跟蹤：

java.lang.AbstractMethodError: javax/persistence/spi/PersistenceProvider.getProviderUtil()Ljavax/persistence/spi/ProviderUtil; 
at javax.persistence.Persistence$1.isLoaded(Persistence.java:78)

at org.springframework.validation.beanvalidation.SpringValidatorAdapter.validate(SpringValidatorAdapter.java:145) 
at general.TestValidationBeans.testTemplateFormBeanValidation(TestValidationBeans.java:30) 

我缺少一些依賴？我使用Hibernate和JPA2註釋作爲持久性，因此所有這些JAR都存在並正在工作。

的Hibernate的版本是：

2011-04-19 08:37:47 [INFO] Version - Hibernate Commons Annotations 3.2.0.Final 
2011-04-19 08:37:47 [INFO] Environment - Hibernate 3.6.2.Final 
2011-04-19 08:37:47 [INFO] Environment - hibernate.properties not found 
2011-04-19 08:37:47 [INFO] Environment - Bytecode provider name : javassist 
... 
2011-04-19 08:37:47 [INFO] Version - Hibernate Validator 4.1.0.Final 

爲什麼isn't Hibernate日誌的Hibernate註解的版本？根據文檔，它是從我正在使用的hibernate3.jar中的hibernate 3.5中捆綁的。
我應該看到日誌Hibernate註解輸出（類似「版本 - Hibernate註解3.4.0 GA）？

Answer 1

我有一個簡單的建立使用上下文配置如下：

MyTest的.java

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration 
public class MyTest { 

    @Autowired 
    private Validator validator; 


    @Test 
    public void testMyForm() { 
     final MyForm form = new MyForm(); 
     . 
     . 
     final Set<ConstraintViolation<MyForm>> violations = validator.validate(form); 
     assertTrue(violations.isEmpty()); 
    } 
} 

MyTest的-context.xml的

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd"> 

    <bean id="validator" 
     class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> 

</beans>

我覺得這個說你已經有了一個版本問題JPA JAR的版本，你必須有。 。從春季預計的一個不同的方法簽名嘗試更新的JAR從春季使用的那些，並看看是否有幫助
