Hibernate的驗證 「無法初始化javax.el.E​​xpressionFactory」 錯誤

Question

我試圖使用Hibernate的驗證，代碼編譯，但在啓動時失敗，錯誤： 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

代碼：

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()); 
    } 
}

我在http://hibernate.org/validator/documentation/getting-started/下面的指南和使用完全相同的依賴，也試圖與在後Running Spring Boot within IntelliJ results in Unable to load 'javax.el.ExpressionFactory'依賴（依賴關係沒有任何彈簧引導代碼，只需用spring-boot-starter-tomcat並沒有部署到Servlet容器）。此外，還嘗試從書「開始春天」的依賴關係：

<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> 

它涉及完全相同的錯誤，但它沒有解決問題。

Answer 1

您有2個不同的javax.el不兼容版本（3和2）。

只要使用這種依賴關係，這將涵蓋一切（這是我們在GitHub庫的README.md建議之一，但我需要更新的入門指南）：

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

，並刪除所有其他的javax .el依賴關係（API和impl）。一旦完成，它應該像魅力一樣工作。
