我如何构造一个ConstraintViolationException？ [英] How do I construct a ConstraintViolationException?

问题描述

我对javax.validation API感到困惑。我正在写一个简单的测试来理解它：

 示例sample = new Sample（）; 
 Set< ConstraintViolation< Sample>> violation = validator.validate（sample）; 
 if（！violations.isEmpty（））{
 // Eclipse拒绝让我使用我的违反变量
抛出新的ConstraintViolationException（违规）; 
} 
  

我应该如何声明这组违规，以便在我的例外中使用它构造函数？

解决方案

您可以像这样解决这个问题：

 throw new ConstraintViolationException（
 new HashSet< ConstraintViolation<>>>（violations））; 
  

您可能有兴趣跟踪 BVAL-198 ，它解决了这个问题。

I am puzzled by the javax.validation API. I am writing a simple test to understand it :

Sample sample = new Sample();
Set<ConstraintViolation<Sample>> violations = validator.validate(sample);
if (!violations.isEmpty()) {
    // Eclipse refuses to let me use my violations variable
    throw new ConstraintViolationException(violations);
}

How should I declare the set of violations so I can use it in my exception constructor?

解决方案

You can work around this like so:

throw new ConstraintViolationException(
    new HashSet<ConstraintViolation<?>>(violations));

You may be interested in tracking BVAL-198 which addresses this issue.
