javax.persistence.PersistenceException: 无法构建实体管理器工厂 org.hibe

Question

嗨，我正在创建我的Web服务，对于数据访问，我在Netbeans IDE中使用了JPA（Hibernate），mysql和Glassfish服务器。

我在访问时遇到以下异常：

**Client Side logs :**

请评论我需要放在这里的任何其他必需文件。

Answer 1

在pom中.xml创建了unknown.binary的文件依赖项。

   <dependency>
        <groupId>unknown.binary</groupId>
        <artifactId>hibernate-jpamodelgen-4.3.1.Final</artifactId>
        <version>SNAPSHOT</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>unknown.binary</groupId>
        <artifactId>mysql-connector-java-5.1.23-bin</artifactId>
        <version>SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>unknown.binary</groupId>
        <artifactId>hibernate-jpamodelgen-4.3.1.Final</artifactId>
        <version>SNAPSHOT</version>
        <scope>provided</scope>
    </dependency>

删除这些依赖项时，将删除无法构建实体管理器工厂错误。
