Hibernate验证器：@Email接受ask @ stackoverflow为有效的？ [英] Hibernate validator: @Email accepts ask@stackoverflow as valid?

问题描述

我使用 @Email 注释来验证电子邮件地址。
我遇到的问题是它接受诸如 ask @ stackoverflow 之类的东西作为有效的电子邮件地址。
我想这是因为他们想要支持Intranet地址，但我似乎无法找到一个标志，因此它检查扩展名。

我真的需要切换到 @Pattern （以及对灵活的电子邮件模式的任何建议）还是我错过了什么？

@Email 解决方案 hibernate-validator / blob / master / engine / src / main / java / org / hibernate / validator / internal / constraintvalidators / EmailValidator.java？source = cc>在内部使用regexp 。您可以根据该regexp轻松定义自己的约束，并根据需要进行修改（请注意结尾处的 + > DOMAIN ）：

  @Target（{ElementType.FIELD，ElementType.METHOD}）
 @Retention（RetentionPolicy.RUNTIME ）
 @Constraint（validatedBy = {}）
 @Pattern（regexp = Constants.PATTERN，flags = Pattern.Flag.CASE_INSENSITIVE）
 public @interface EmailWithTld {
 String message（ ）默认的错误的电子邮件; 
 Class<？> [] groups（）default {}; 
 Class <？扩展了Payload> [] payload（）default {}; 
} 
 
接口常量{
 static final String ATOM =[a-z0-9！＃$％&'* + / =？^ _`{|} 〜 - ]; 
 static final String DOMAIN =（+ ATOM ++（\\。+ ATOM ++）+; 
 static final String IP_DOMAIN =\\ [[0 -9] {1,3} \\。[0-9] {1,3} \\。[0-9] {1,3} \\。[0-9] {1 ，3} \\]; 
 
 static final String PATTERN = 
^+ ATOM ++（\\。+ ATOM ++）* @ 
 + DOMAIN 
 +|
 + IP_DOMAIN 
 +）$; 
} 
  

I'm using the @Email annotation to validate an e-mail address. The issue I'm having is that it's accepting things like ask@stackoverflow as a valid e-mail address. I guess this is because they want to support intranet addresses, but I can't seem to find a flag so it does check for an extension.

Do I really need to switch to @Pattern (and any recommendations for an e-mail pattern that's flexible) or am I missing something?

解决方案

Actually, @Email from Hibernate Validator uses regexp internally. You can easily define your own constraint based on that regexp, modified as you need (note the + at the end of DOMAIN):

@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = {})
@Pattern(regexp = Constants.PATTERN, flags = Pattern.Flag.CASE_INSENSITIVE)
public @interface EmailWithTld {
    String message() default "Wrong email";
    Class<?>[] groups() default { };
    Class<? extends Payload>[] payload() default { };
}

interface Constants {
    static final String ATOM = "[a-z0-9!#$%&'*+/=?^_`{|}~-]";
    static final String DOMAIN = "(" + ATOM + "+(\\." + ATOM + "+)+";
    static final String IP_DOMAIN = "\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\]";

    static final String PATTERN =
            "^" + ATOM + "+(\\." + ATOM + "+)*@"
                    + DOMAIN
                    + "|"
                    + IP_DOMAIN
                    + ")$";
}
