我正在使用 Oval 进行验证。我正在使用弹簧批处理来填充（csv 到对象）一个对象并使用 Oval 对其进行验证。但我认为我的@javax.validation.constraints.Pattern 不起作用，因为我的控制台在我运行程序时没有显示错误。

这是我的课：

您需要激活对 bean 验证约束的解释，如http://oval.sourceforge.net/userguide.html#interpreting-bean-validation-annotations中所述

// configure OVal to interprete OVal constraint annotations as well as built-in JSR303 annotations
Validator validator = new Validator(new AnnotationsConfigurer(), new BeanValidationAnnotationsConfigurer());
