JPA 2.0：在JPA 2.0中使用javax.validation。*包的例外 [英] JPA 2.0 : Exception to use javax.validation.* package in JPA 2.0

问题描述

当我尝试使用使用hibernate的JPA进行bean验证时，会发生以下异常：

我新使用验证软件包，并且我还没有掌握JAVA EE bean的知识。

  public class Employee实现Serializable，EmployeeDetail {
 
 
 private static final long serialVersionUID = 1L; 
 @Id 
 @GeneratedValue 
 private int id; 
 @NotNull 
私人字符串名称; 
 ____________________ 
 
 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（）; 
  

解决方案

与 validation-api-1.0.x 不兼容。这是因为转向新的规范JSR-303 - > JSR-349。

有两种方法可以解决这个问题：

1。降级hibernate验证器版本（实现JSR-303）：

 <依赖性> 
< groupId> org.hibernate< / groupId> 
< artifactId> hibernate-validator< / artifactId> 
< version> 4.3.1.Final< / version> 
< /依赖关系> 
  

2。如果您不想从hibernate验证器5到hibernate验证器4另一个解决方案是将javax.validation升级到更高版本（这是描述JSR-349）：

 < ;依赖性> 
< groupId> javax.validation< / groupId> 
< artifactId> validation-api< / artifactId> 
< version> 1.1.0.Final< / version> 
< /依赖关系> 
  

when i try to using bean validation with JPA using hibernate , the follwoing exception will occur :

i am new to use validation package and i have not knowledge of JAVA EE beans . how to use this validation package with jpa entity following is my code :

 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();

解决方案

As @Korgen mentioned in comments hibernate-validator-5.x.x doesn't compatible with validation-api-1.0.x. This is because of moving to new specification JSR-303 -> JSR-349.

There are two ways to solve this issue:

1. Downgrade hibernate validator version (which is implements JSR-303):

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

2. If you don't want to move back from hibernate validator 5 to hibernate validator 4 another solution is to upgrade javax.validation to higher version (which is describe JSR-349):

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