java - 类级约束验证错误使 Arjuna TwoPhaseCoordinator.beforeCompletion 失败

Question

我试图以 this here 的风格创建一个更复杂的跨域 Bean 验证.当我在验证我的实体实例时返回 false 时，问题很快就变成了一个问题，它被传递给了我的自定义 validator 。

因此，我创建了一个字段级约束注释，如 Hibernate tutorial 中所述，但更简单。实际上我的验证只是:

@Overrides
public bool isValid(Object value, ConstraintValidatorContext arg1){
    System.out.println("##### isValid call for example.");
    return false;
}

这非常有效。一旦我用注释对字段进行注释，任何持久性尝试都会被粉碎，该字段被标记为无效。

现在回到我的类级 validator :

@Target({TYPE, ANNOTATION_TYPE})
@Retention(RUNTIME)
@Constraint(validatedBy = CrossFieldConstraintValidator.class)
public @interface CrossFieldConstraint {

    String message() default "CrossFieldConstraint violation";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

这里没什么可看的，只有你的标准约束注解，它定义了一条消息，它被验证的地方以及它可能被放置的地方。

现在，当将它传递给我的 CrossFieldConstraintValidator 时，我收到了一些超长的堆栈跟踪。我将粘贴一个“略微”缩短的版本，它保留了所有:引起的，但删除了它的一些踪迹......

然后我开始越来越多地降低问题的复杂性，直到我到达那个地步，我的 CrossFieldConstraintValidator 只不过是:

public class CrossFieldConstraintValidator 
       implements ConstraintValidator<CrossFieldConstraint, Object>{
    @Override
    public void initialize(final CrossFieldConstraint annotation) {

    }

    @Override
    public boolean isValid(Object value, ConstraintValidatorContext validatorContext) {
    try{
        System.out.println("### isValid - " + value + "  " + validatorContext.toString());

        return false;       
    }catch(Exception logIt){
        System.out.println("Validation Failed with Exception: " +  logIt.toString());
        System.out.println("ValidatorContext: "+ validatorContext.toString());
        return false;
    }
}

但是我还是报了同样的错误。我在 JBoss 7.1.1.Final 上运行并使用 Primefaces。

我传递的实体是这样的:

@Entity
@CrossFieldConstraint
public class Project{

  @Id
  @GeneratedValue
  private long id;

  @ManyToOne
  private Customer owner;
}

持久化以下列方式发生在服务类中:

@Inject
EntityManager entityManager;

public void add(Project proj, long ownerId){
   Customer managedOwner = entityManager.find(Customer.class, ownerId);
   proj.setCustomer(managerCustomer);
   entityManager.persist(proj);
}

Answer 1

我决定忽略来自 Arjuna 的警告，现在改为捕获 EJBTransactionRolledBackException。缺少的部分是我需要从我使用的 Controller 中的 View 停止延迟。

public boolean processSave(){
   boolean success = true;
   try{
      //persistence operation via service class
   }
   catch(OptimisticLockException e){
      success = false;
      //add a faces message
   }
   catch(EJBTransactionRolledbackException e){
      success = false;
      //add another faces message
   }
   return success;
}

作为一个小信息，这是用于保存 View 操作的代码:

/**
* Triggers the save process as business logic and uses the result to determine
* what to return
* @return Navigation rule as String depending on the outcome of the save process
*/
public String save() {
   return processSave() ? navigationRuleSuccess : navigationRuleFailure;
}
