java–Autowired在Custom Constraint验证器中给出Null值

我对Spring来说是全新的,我已经在SO上找到了一些问题的答案.以下是链接：

Spring 3.1 Autowiring does not work inside custom constraint validator

Autowiring a service into a validator

Autowired Repository is Null in Custom Constraint Validator

我有一个Spring项目,我想在其中使用Hibernate ValIDator进行对象验证.基于我在网上阅读的内容和一些论坛,我试图注入验证器如下：

@Bean  public ValIDator valIDator() {    return new LocalValIDatorfactorybean().getValIDator();  }

但无论我在哪里使用

@autowiredValIDator valIDator;

它采用了Spring的验证器实现而不是Hibernate的验证器.我无法弄清楚如何准确地注入Hibernate验证器并简单地将其自动装配到其他类中,所以我使用了一个便宜的技巧,现在我的Java Config看起来像这样

@Bean      public ValIDator valIDator() {        // ValIDatorImpl is Hibernate's implementation of the ValIDator        return new ValIDatorImpl();      }

(我真的很感激,如果有人能指出我如何避免以这种Hacky方式获得Hibernate ValIDator的正确方向)

但是让我们来看看主要问题：

这是自定义验证定义

@Target( { METHOD,FIELD,ANNOTATION_TYPE,CONSTRUCTOR,ParaMETER } )@Retention(RUNTIME)@Constraint(valIDatedBy = EmployeeValIDator.class)@documentedpublic @interface EmployeeValIDation {String message() default "{constraints.employeeConstraints}";public abstract Class

我的自定义验证器

public class EmployeeValIDator implements ConstraintValIDator

在上面的Custom Constraint ValIDator中,我得到employeeService null.我知道Spring启动时没有实例化ConstraintValIDator的任何实现,但我认为添加ValIDatorImpl()实际上会解决这个问题.但事实并非如此.

现在我陷入了一个非常Hacky的解决方法,我不想继续这样的代码.有人可以帮助我解决我的情况.

附：这些是我在Java Config文件中的导入：

@Beanpublic ValIDator valIDator () {    ValIDatorFactory valIDatorFactory = ValIDation.byProvIDer( HibernateValIDator.class )        .configure().constraintValIDatorFactory(new SpringConstraintValIDatorFactory(autowireCapablebeanfactory))        .buildValIDatorFactory();    ValIDator valIDator = valIDatorFactory.getValIDator();    return valIDator;}

ValIDator valIDator(final autowireCapablebeanfactory autowireCapablebeanfactory) {

public autowireCapablebeanfactory getautowireCapablebeanfactory() {        return autowireCapablebeanfactory;}public voID setautowireCapablebeanfactory(autowireCapablebeanfactory autowireCapablebeanfactory) {        this.autowireCapablebeanfactory = autowireCapablebeanfactory;}
