橢圓驗證框架 - @ javax.validation.constraints.Pattern（不工作）的實現

我正在用橢圓進行驗證。我正在使用spring批處理來填充（csv到對象）對象並使用Oval進行驗證。但是我認爲我的@ javax.validation.constraints.Pattern不起作用，因爲當我運行該程序時，控制檯不顯示錯誤。橢圓驗證框架 - @ javax.validation.constraints.Pattern（不工作）的實現

這裏是我的clases：

這是我的CSV：

記錄激活的Bean驗證約束的解釋和又何必呢？模式只適用於基於文本的屬性而不是數字，日期等。所以基本上在'字符串'將工作。你的其他人幾乎沒用。 –

您需要作爲http://oval.sourceforge.net/userguide.html#interpreting-bean-validation-annotations

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