我在Spring中使用JSR-303来验证密码字段。我想将所有验证逻辑放在一个类中,并相应地显示每个错误的消息。这可能吗?为每个验证检查创建一个单独的类(即PasswordLengthValidator,PasswordRegexValidator)更好吗?
目前,我只能根据密码界面显示1条错误消息。
这是@Password注释的界面:
@Documented
@Constraint(validatedBy = PasswordValidator.class)
@Target( { ElementType.METHOD, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
public @interface Password {
String message() default "{Password}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
这是我的验证员类:
public class PasswordValidator implements ConstraintValidator<Password, String> {
public void initialize(Password arg0) {
// TODO Auto-generated method stub
}
public boolean isValid(String field, ConstraintValidatorContext ctx) {
// TODO validation validation validation
if(StringUtils.isEmpty(field)) {
// Message: password can not be empty
return false;
}
// match some password regex
if(field.matches("^(?=.*[A-Z].*[A-Z])(?=.*[!@#$&*])(?=.*[0-9].*[0-9])(?=.*[a-z].*[a-z].*[a-z]).{8}$")) {
// Message: password should be bla bla
return false;
}
return true;
}
}

您的验证工具可以使用ConstraintValidatorContext
API发送验证消息:
context.buildConstraintViolationWithTemplate( "this detail is wrong" )
.addConstraintViolation();
// [..]
context.buildConstraintViolationWithTemplate( "that detail is wrong" )
.addPropertyNode( "street" )
.addConstraintViolation();
