Hibernate验证＆＃34;无法初始化javax.el.E​​xpressionFactory＆＃34;错误

我尝试使用hibernate验证，代码编译，但是在启动时失败并出现错误： Exception in thread "main" javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

代码：

import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;

public class Run {
    public static void main(String[] args) {    
    User u = new User();
    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator v = factory.getValidator();
    Set<ConstraintViolation<User>> result = v.validate(u);
    System.out.println(result.size());
    }
}

用户类：

import javax.validation.constraints.Pattern;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;

public class User {

        @Pattern(regexp="[a-zA-Z0-9_]{5,10}", message="Username must be 5 to 10 characters long, " + 
                "only digits, letters and underscore permitted.")
        @XmlAttribute(name = "username", required = true)
        protected String username;

        @Pattern(regexp="[0-9a-zA-Z]{5,10}", message="Password must be 5 to 10 characters long, " + 
                "only digits and letters permitted.")
        @XmlAttribute(name = "passwd", required = true)
        protected String passwd;

        @NotNull
        @XmlAttribute(name = "authToken", required = true)
        protected String authToken;

        Getters and setters...

我在http://hibernate.org/validator/documentation/getting-started/上关注指南并使用完全相同的依赖关系，也尝试使用post Running Spring Boot within IntelliJ results in Unable to load 'javax.el.ExpressionFactory'中的依赖关系（没有任何Spring启动代码，只有spring-boot-starter-tomcat依赖关系并且没有部署到servlet容器）。还试过了书＃34; Beginning Spring＆＃34;：

<dependency>
    <groupId>javax.el</groupId>
    <artifactId>javax.el-api</artifactId>
    <version>3.0.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

涉及完全相同的错误，但它没有解决问题。

您有两种不同版本的javax.el（3和2）。

只需使用此依赖项，它将涵盖所有内容（这是我们在GitHub repo的README.md中推荐的那个，但我需要更新入门指南）：

<dependency>
   <groupId>org.glassfish</groupId>
   <artifactId>javax.el</artifactId>
   <version>3.0.1-b08</version>
</dependency>

并删除所有其他javax.el依赖项（API和impl）。一旦你完成它就应该像魅力一样。

以上都不适合我 然而，这样做： 右键单击项目＆gt;属性＆gt;项目方面 在最右边的区域选择Runtimes选项卡并选择你的Tomcat Runtime，这将提供测试可用的必需库。 enter image description here
