Java 创建JPA生产者终结点时出错

我不熟悉骆驼。我正在为下面的场景编写一条骆驼路线

从某个位置拾取XML文件

根据XSD验证XML文件

将XML数据持久化到数据库中

我是这样写的

public void configure() throws Exception {
           JaxbDataFormat jaxb = new JaxbDataFormat();
           JAXBContext ctx = JAXBContext.newInstance(Book.class);
           jaxb.setContext(ctx);

           from("file:data/source?noop=true").to("validator:books.xsd")
                                         .to("file:data/destination").split()
                                         .tokenizeXML("book").unmarshal(jaxb)
                                         .to("jpa:com.labs.Book");
}

我的XML文件是：

<book>
           <author>Kishore</author>
           <title>The Second Book</title>
           <genre>Fiction</genre>
</book>

基肖尔
第二本书
小说

我的XSD是：

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="book">
    <xs:complexType>
      <xs:sequence>
        <xs:element type="xs:string" name="author" nillable="false"/>
        <xs:element type="xs:string" name="title" nillable="false"/>
        <xs:element type="xs:string" name="genre" nillable="false" fixed="{Fiction,Bio}"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

我有XML的JAXB模型。我还有pesristence.xml文件。但当我试图执行我的应用程序时，我得到了一个如下所示的异常
