当我尝试使用休眠的 JPA 使用 bean 验证时，将发生以下异常：

我是使用验证包的新手，我不了解 JAVA EE bean。如何将此验证包与 jpa 实体一起使用以下是我的代码：

 public class Employee implements Serializable , EmployeeDetail{


private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private int id;
@NotNull
private String name;
    ____________________

public class Test {
public static void main(String[] args) {
    EntityManagerFactory emf = Persistence.createEntityManagerFactory("Chapter11");
    EntityManager em = emf.createEntityManager();
    EntityTransaction etr = em.getTransaction();

    etr.begin();
            ------------------

        FullTimeEmployee flEmp = new FullTimeEmployee();
        flEmp.setName("Harmeet Singh");
        flEmp.setPension(56000);
        flEmp.setSalary(100000);

        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
        Validator validator = factory.getValidator();
        validator.validate(flEmp, Employee.class);

        em.persist(flEmp);
    etr.commit();

正如评论中提到的@Korgen hibernate-validator-5.xx与validation-api-1.0.x不兼容。这是因为迁移到新规范 JSR-303 -> JSR-349。

有两种方法可以解决这个问题：

1.降级休眠验证器版本（实现 JSR-303）：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.3.1.Final</version>
</dependency>

2.如果您不想从休​​眠验证器 5 移回休眠验证器 4，另一种解决方案是将 javax.validation 升级到更高版本（描述 JSR-349）：

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.1.0.Final</version>
</dependency>

对于那些遇到错误NoClassDefFoundError: javax/validation/valueextraction/ValueExtractorDeclarationException并且他们的验证 API 已经存在的人javax.validation:validation-api:1.1.0.Final

修复是从升级javax.validation:validation-api:1.1.0.Final到javax.validation:validation-api:2.0.1.Final.
