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+$)",message = "Password must contain no whitespace.") private String password;
但是,我不能这样做.我想要在密码字段上违反正则表达式约束的个别消息.这可能吗？
解决方法
您可以使用@Pattern的内部@List注释：
@Pattern.List({
@Pattern(regexp = "(?=.*[0-9])",message = "Password must contain one digit."),@Pattern(regexp = "(?=.*[a-z])",message = "Password must contain one lowercase letter."),@Pattern(regexp = "(?=.*[A-Z])",message = "Password must contain one uppercase letter."),@Pattern(regexp = "(?=\\S+$)",message = "Password must contain no whitespace.")
})
private String password;
