我想使用Hibernate Validator,我在第一步检查并研究了以下参考资料:
第3页的第一个样本是我的问题
我没有找到这个导入包(javax.validation。*)
在hibernate-validator-5.0.2.Final.jar
中我发现只有(org.hibernate.validator。*),但这些类不存在
package org.hibernate.validator.referenceguide.chapter01;
import java.util.Set;
// ?????
import javax.validation.ConstraintViolation; // Not Found
import javax.validation.Validation; // Not Found
import javax.validation.Validator; // Not Found
import javax.validation.ValidatorFactory; // Not Found
// ?????
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class CarTest {
private static Validator validator;
@BeforeClass
public static void setUp() {
// ?????
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
// ?????
}
@Test
public void manufacturerIsNull() {
Car car = new Car(null, "DD-AB-123", 4);
Set<ConstraintViolation<Car>> constraintViolations
= validator.validate(car);
assertEquals(1, constraintViolations.size());
assertEquals("may not be null", constraintViolations.iterator().next().getMessage());
}
请帮助我并指导以下代码的必要软件包?
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
答案 0 :(得分:1)
您需要将validation-api jar添加到类路径中。最新版本为validation-api-1.1.0.Final.jar
。类javax.validation.*
包含在这个jar中。
