javax.validation.ValidationException：HV000183：無法加載 'javax.el.E​​xpressionFactory'

Question

我試着寫與Hibernate驗證非常簡單的應用：

我的步驟：在pom.xml中

添加以下依賴：

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

寫代碼：

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); 

    } 
} 

而且我得到以下stacktra ce：

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 

我該怎麼做？

Answer 1

它也加入到pom.xml以下相關工作後：

<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>

做到這

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

如果您正在使用Tomcat作爲服務器運行時，你會得到此錯誤測試（因爲tomcat運行時在測試期間是不可用的）比包含tomcat el運行時而不是來自glassfi的運行時有意義SH）。這將是：

<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> 
    </dependency>

關於Hibernate validator documentation page，你必須定義一個依賴於JSR-341實現：

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