如何在Spring MVC驗證中禁用消息中的花括號替換

Question

我有@Pattern注釋的字段

最終公開課分支機構{

@Pattern( regexp = "([0-9]{1}[1-9]{1}|[1-9]{1}[0-9]{1})[0-9]{8}", message = "Inn should be validated by pattern \"{regexp}\". Check branch settings" )
private String INN;

}

春季形式：錯誤標簽

   <form:errors path="*"/>

如果我輸入了錯誤的INN字段，則會收到違規消息

Inn should be validated by pattern ([0-9][Ljavax.validation.constraints.Pattern$Flag;@4a5b4234[1-9][Ljavax.validation.constraints.Pattern$Flag;@4a5b4234|[1-9][Ljavax.validation.constraints.Pattern$Flag;@4a5b4234[0-9][Ljavax.validation.constraints.Pattern$Flag;@4a5b4234)[0-9]{8}.. Check branch settings

Spring用其他對象替換了我的regexp中的花括號。 例如，將{1}替換為Ljavax.validation.constraints.Pattern $ Flag; @ 4a5b4234如何禁用此煩人的行為？

您還需要用簡單的引號（ \\"'{regexp}'\\" ）轉義{regexp}部分，以使Spring忽略它：

@Pattern(regexp = "([0-9]{1}[1-9]{1}|[1-9]{1}[0-9]{1})[0-9]{8}", message = "Inn should be validated by pattern \"'{regexp}'\". Check branch settings")
