创建一个bean时出错“entityManagerFactory”

Question

我有一个使用JavaFX的Spring Boot项目。当我运行这个项目的想法，一切工作正常，但经过使用Maven我包项目我得到尝试运行jar文件

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' 
Invocation of init method failed;nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException 

的pom.xml此异常时此

<dependencies> 
    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-data-jpa</artifactId> 
    </dependency> 

    <dependency> 
     <groupId>com.h2database</groupId> 
     <artifactId>h2</artifactId> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-test</artifactId> 
     <scope>test</scope> 
    </dependency> 
</dependencies> 

Answer 1

尝试增加这些依赖关系到您的POM：

<dependency> 
    <groupId>javax.xml.bind</groupId> 
    <artifactId>jaxb-api</artifactId> 
</dependency> 

<dependency> 
    <groupId>com.sun.xml.bind</groupId> 
    <artifactId>jaxb-impl</artifactId> 
</dependency> 

也许您需要为软件包添加版本。
