无法通过maven jaxb插件生成注释

我试图添加javax.persistence.Id作为对一个字段的注释并通过Maven JAXB插件生成为Java对象。然而，我碰到类没有发现javax.persistence.id异常我确保javax.persistence包含在maven依赖项中，我看到maven将它作为依赖项，但是当我通过jaxb插件运行时，它将无法工作。无法通过maven jaxb插件生成注释

这里是我的XML <xsd:complexType name="MyTable"> <xsd:sequence> <xsd:element name="id" type="xsd:int"/> </xsd:sequence> </xsd:complexType>
这里是我的binding.xjb文件

<jaxb:bindings version="2.1" 
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
    xmlns:annox="http://annox.dev.java.net" jaxb:extensionBindingPrefixes="annox"> 

<jaxb:bindings schemaLocation="mytable.xsd"> 

    <jaxb:bindings node="xs:complexType[@name='MyTable']/xs:sequence/xs:element[@name='id']"> 
     <annox:annotate target="field"> 
      <annox:annotate annox:class="javax.persistence.Id"/> 
     </annox:annotate> 
    </jaxb:bindings> 

</jaxb:bindings>

但是当我运行的Maven - >生成来源我得到这个错误

    at org.jvnet.annox.parser.XAnnotationParser.parse(XAnnotationParser.java:90)

Caused by: org.jvnet.annox.annotation.AnnotationClassNotFoundException: Annotation class [javax.persistence.Id] could not be found. 
    ... 33 more 
Caused by: java.lang.ClassNotFoundException: javax.persistence.Id

如果我只是@Id注释添加到项目中的任何Java类，那么我可以补充，我看到越来越javax.persistence.Id进口没问题。当我使用maven & binding.xjb时出了什么问题？我没有正确定义注释吗？非常感谢！

我想这也是我有同样的问题：你添加javax.persistence作为Maven的依赖，但不能作为依赖于你的JAXB插件：

添加这样的事情（如果你使用Hibernate）：

</project> 
    ... 
    <build> 
     <plugins> 
     <plugin> 
      <groupId>org.jvnet.jaxb2.maven2</groupId> 
      <artifactId>maven-jaxb2-plugin</artifactId> 
      <version>${maven-jaxb2-plugin.version}</version> 
      <executions> 
      ... 
      </executions> 
      <configuration> 
      ... 
      </configuration> 
      <dependencies> 
      <!-- Hibernate Persistence Annotations --> 
      <dependency> 
       <groupId>org.hibernate.javax.persistence</groupId> 
       <artifactId>hibernate-jpa-2.0-api</artifactId> 
       <version>${hibernate-jpa-2.0-api.version}</version> 
      </dependency> 
      </dependencies> 
     </plugin> 
     </plugins> 
    </build> 
    ... 
</project>

我有一个类似的问题，并能解决这个问题。在下面的示例中，请注意我将注释放入XSD中，而不是放入XJB文件中，但Maven配置应该类似。

这里是我的XSD：

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.1"

    xmlns:annox="http://annox.dev.java.net" 
    xmlns:ja="http://annox.dev.java.net/javax.xml.bind.annotation" 
    xmlns:jpa="http://annox.dev.java.net/javax.persistence" 
    xmlns:solrj="http://annox.dev.java.net/org.apache.solr.client.solrj.beans" 
    xmlns:jackson="http://annox.dev.java.net/com.fasterxml.jackson.annotation"> 

... 
<xs:element name="Certificate"> 
    <xs:annotation> 
    <xs:appinfo> 
     <annox:annotate> 
     <ja:XmlAccessorType value="NONE"/> 
     <jpa:Entity name="Certificate"/> 
     <solrj:Field value="testByOrderOf"/> 
     <jackson:JsonFormat shape="STRING" pattern="yyyy-MM-dd'T'HH:mm:ss'Z'" timezone="GMT"/> 
     </annox:annotate> 
    </xs:appinfo> 
    </xs:annotation> 
    ... 
    <xs:element ref="ew:dateOfBirth"> 
    <xs:annotation> 
     <xs:appinfo> 
     <annox:annotate target="field"> 
      <solrj:Field value="dateOfBirth"/> 
      <jackson:JsonFormat shape="STRING" pattern="yyyy-MM-dd'T'HH:mm:ss'Z'" timezone="GMT"/> 
     </annox:annotate> 
     </xs:appinfo> 
    </xs:annotation> 
    </xs:element> 
    ... 
</xs:element>

我有同样的例外，这个固定。请注意，我的示例将所有内容都放入XSD中，而不是放入XJB中，但上面提到的依赖项也可以帮助您。
