本文介绍了Hibernate 验证“无法初始化 javax.el.E​​xpressionFactory"错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用休眠验证，代码编译，但在启动时失败并出现错误:线程主"javax.validation.ValidationException 中的异常:HV000183:无法初始化javax.el.E​​xpressionFactory".检查类路径上是否有 EL 依赖项，或者改用 ParameterMessageInterpolator

I'm trying to use hibernate validation, code compiles, but when launched in fails with error: 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());
    }
}

我遵循 http://hibernate.org/validator/documentation/getting-started 的指南/ 并使用完全相同的依赖项，也尝试使用 post 在 IntelliJ 中运行 Spring Boot 导致 Unable to load 'javax.el.E​​xpressionFactory' (没有任何 Spring Boot 代码，只需使用 spring-boot-starter-tomcat 在依赖项中并且没有部署到 servlet 容器).还尝试了Beginning Spring"一书中的依赖项:

I following guide at http://hibernate.org/validator/documentation/getting-started/ and use exactly same dependencies, also tried with dependencies in post Running Spring Boot within IntelliJ results in Unable to load 'javax.el.ExpressionFactory' (without any spring boot code, just with spring-boot-starter-tomcat in dependencies and without deploying to servlet container). Also tried dependencies from book "Beginning Spring":

<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>

这涉及完全相同的错误，但它并没有解决问题.

which concerns exactly same error, but it didn't solve the problem.

推荐答案

你有 2 个不兼容的 javax.el 版本(3 和 2).

You have 2 different incompatible versions of javax.el (3 and 2).

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

Just use this dependency, which will cover everything (it's the one we recommend in the GitHub repo's README.md but I need to update the getting started guide):

<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).完成后，它应该会像魅力一样发挥作用.

and remove all the other javax.el dependencies (API and impl). It should work like a charm once you're done.
