javax.validation.ValidationException: HV000183:无法加载'javax.el.ExpressionFactory‘

我尝试用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);
}
}我得到了下面的堆栈跟踪：
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我做错了什么？

就这么做
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>2.2.4</version>

如果您使用tomcat作为服务器运行时，并且在测试中遇到此错误(因为tomcat运行时在测试期间不可用)，那么包含tomcat el运行时而不是glassfish中的运行时是有意义的。这将是：
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-el-api</artifactId>
<version>8.5.14</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jasper-el</artifactId>
<version>8.5.14</version>
<scope>test</scope>

如果你使用的是spring boot和starters --这个依赖项同时添加了tomcat-embed-el和hibernate-validator依赖项：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
