hibernate-validator

问题 I have an entity on which I need to implement the following constraint: "There may only ever be one record for any combination of columns X and Y, for which column Z is null if the record is of type A." The last part turns this from a simple uniqueness constraint to something more complex. I'm writing a custom Hibernate validator to check it. What I'm doing is: @Override public boolean isValid(MyEntity value, ConstraintValidatorContext context) { Query query = DB.createQuery( // DB is just a

问题 I know that exist annotation @Future. If I annotate field with this annotation @Future private Date date; date must be in future means after current moment. Now I need to validate that date was at least 24 hours after current moment. How can I make it? 回答1: AfterTomorrow.java: @Target({ FIELD, METHOD, PARAMETER }) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy = AfterTomorrowValidator.class) @Documented public @interface AfterTomorrow { String message() default "{AfterTomorrow

问题 Is it possible to turn off certain constraints / annotations per class at runtime? For instance if I wanted to turn of a @NotNull check on a firstName field, is that possible? This would make testing to see whether a certain constraint is triggered correctly simpler, as I could turn off all the other constraints, and just check that one constraint. 回答1: Is it possible to turn off certain constraints / annotations per class at runtime?

问题 I am using Hibernate validator for form validation in my web-app. I am using the @Length annotation for my String attribute as follows: @Length(min = 5, message = "The field must be at least 5 characters") private String myString; However, I have a need to display a different message if the String exceeds 50 characters. Is there a way to use the out-of-the-box @Length validator to do this? An example of what I would like to do (compiler will not let me) is as follows: @Length(min = 5, message

问题 In my Spring project I have a POJO class with a property for a CMYK color. I want this property to be represented by a JSON array with exactly 4 floating-point numbers. Each number must be in the range between 0.0 and 1.0 . Currently I'm struggling with the validation of this property. I have researched already and found that the @DecimalMin and @DecimalMax annotations cannot be used on Float or float (see the answers to this question). Therefore I already abandoned List<Float> and use List

问题 I have a class: @ColumnNameUnique(groups = CreateTableChecks.class) public class Table { @Valid @NotEmpty(groups = CreateTableChecks.class) private List<Measure> measures; } The class level constraint @ColumnNameUnique(groups = CreateTableChecks.class) always runs first, after that the field level constraint @NotEmpty(groups = CreateTableChecks.class) runs. Is there anyway to force the the field level constraint @NotEmpty(groups = CreateTableChecks.class) runs first? 回答1: You need to use

问题 Does Hibernate validators supports internationalization. I saw the jar and I could see the various ValidationMessages.properties file. Can we create our own custom error messages which will be internationalized? I don't want to use error messages provided by default in Hibernate validators. We need to use our own custom message and they should be internationalized. As well what are the languages supported by the Hibernate validators. In jar I saw properties files for the English, French,

问题 Details: I am making form-validation using javax-validation and hibaernate-validator in Spring. Other than basic necessary JAR files for Spring. I have included: validation-api-1.1.0.Final hibernate-validator-5.1.0.Final I read somewhere that spl4j version is also in concern: so I'm also telling: ###slf4j-api-1.7.5### ###slf4j-simple-1.7.5### ###log4j-1.2.17### Can the cause of error be due to slf4j and log4j compatibility? I use annotation base validation. Let me provide some code: Customer
