regex - 1个字段使用多个正则表达式@Pattern？

Question

我试图将多个@Pattern注释应用于单个字段:

@Pattern(regexp = "(?=.*[0-9])", message = "Password must contain one digit.")
@Pattern(regexp = "(?=.*[a-z])", message = "Password must contain one lowercase letter.")
@Pattern(regexp = "(?=.*[A-Z])", message = "Password must contain one uppercase letter.")
@Pattern(regexp = "(?=\S+$)", message = "Password must contain no whitespace.")
private String password;

但是，我不能这样做。我希望每个密码字段上违反正则表达式约束的邮件。这可能吗？

我的替代方法是使用JSF 2.0 f:validatorRegex标记。

您可以使用@List的内部@Pattern批注:

@Pattern.List({
    @Pattern(regexp = "(?=.*[0-9])", message = "Password must contain one digit."),
    @Pattern(regexp = "(?=.*[a-z])", message = "Password must contain one lowercase letter."),
    @Pattern(regexp = "(?=.*[A-Z])", message = "Password must contain one uppercase letter."),
    @Pattern(regexp = "(?=\\S+$)", message = "Password must contain no whitespace.")
})
private String password;
