我的bean中有一个String列表.这些字符串是电子邮件,我想验证它们.

@Email
@ElementCollection(fetch = FetchType.LAZY)
@OrderColumn
private List<String> emails = new ArrayList<String>();

在执行时,我收到此错误:

Caused by: javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: java.util.List<java.lang.String>.

    ...

这样做的正确方法是什么？或者还有其他方法吗？
