javax.validation.ValidationException：HV000183：无法加载'javax.el.E​​xpressionFactory'

Question

我尝试使用hibernate验证器编写非常简单的应用程序：

我的步骤：

在pom.xml中添加以下依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.1.1.Final</version>
</dependency>

编写代码：

class Configuration {
    Range(min=1,max=100)
    int threadNumber;
    //...

    public static void main(String[] args) {
        ValidatorFactory factory = Validation.buildDefaultValidatorFactory();

        Validator validator = factory.getValidator();

        Configuration configuration = new Configuration();
        configuration.threadNumber = 12;
            //...

        Set<ConstraintViolation<Configuration>> constraintViolations = validator.validate(configuration);
        System.out.println(constraintViolations);

    }
}

我得到以下stacktrace：

Exception in thread "main" javax.validation.ValidationException: Unable to instantiate Configuration.
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:279)
    at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:110)
    ...
    at org.hibernate.validator.internal.engine.ConfigurationImpl.<init>(ConfigurationImpl.java:110)
    at org.hibernate.validator.internal.engine.ConfigurationImpl.<init>(ConfigurationImpl.java:86)
    at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:41)
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:276)
    ... 2 more

我怎么了

添加到pom.xml以下依赖项后，它可以工作：

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>
<dependency>
   <groupId>org.glassfish.web</groupId>
   <artifactId>javax.el</artifactId>
   <version>2.2.4</version>
</dependency>

Hibernate Validator入门：

Hibernate Validator还需要实现统一表达式语言（JSR
341
）来评估约束违例消息中的动态表达式。当您的应用程序在WildFly之类的Java
EE容器中运行时，该容器已经提供了EL实现。但是，在Java SE环境中，必须将实现添加为对POM文件的依赖。例如，您可以添加以下两个依赖项以使用JSR
341 参考实现：

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>
<dependency>
   <groupId>org.glassfish.web</groupId>
   <artifactId>javax.el</artifactId>
   <version>2.2.4</version>
</dependency>
