我正在尝试将hbm2java maven插件用于hibernate。对于mvn hibernate3：hbm2cfgxml目标我面临以下错误。

我在POM.xml中添加了以下插件配置以使用hbm2java功能。

<build>
<plugins>
  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>hibernate3-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
      <components>
        <component>
          <name>hbm2ddl</name>
          <implementation>jdbcconfiguration</implementation>
        </component>
        <component>
          <name>hbm2hbmxml</name>
          <outputDirectory>src/main/resources</outputDirectory>
        </component>
      </components>
      <componentProperties>
        <drop>true</drop>
        <configurationfile>/src/main/resources/hibernate.cfg.xml</configurationfile>
      </componentProperties>
    </configuration>
    <dependencies>
      <dependency>
        <groupId>jdbc.artifact.groupid</groupId>
        <artifactId>jdbc-driver</artifactId>
        <version>1.0</version>
      </dependency>
    </dependencies>
  </plugin>
</plugins>

我在哪里可以找到jdbc.artifact.groupid以及我的pom.xml中缺少的内容？

Answer 1

您必须使用真实的供应商工件替换jdbc.artifact.groupid：jdbc-driver：1.0。例如

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <version>2.2.8</version>
</dependency>

如果你使用hsqldb。

编辑

正如您所提到的，您在评论中使用了Oracle ... Oracle db的jdbc jar随Oracle发行版一起提供。您也可以下载here。下载后，您必须手动将其放入当地的maven仓库（如果您有的话，还可以将其存储在Maven Repo Manager的thirparty回购中（Nexus，Archiva .. 。）。另一种方法是使用systemPath声明添加依赖项：

<dependency>
   <groupId>com.oracle.jdbc</groupId>
   <artifactId>ojdbc6_g</artifactId>
   <version>11.2.0.2.0</version>
   <systemPath>"C:/ThirpartyJars/Oracle/ojdbc6_g.jar"</systemPath>
</dependency>

Answer 2

替换您的依赖

   <dependency>
    <groupId>jdbc.artifact.groupid</groupId>
    <artifactId>jdbc-driver</artifactId>
    <version>1.0</version>
  </dependency>

到

   <dependency>
     <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
         <version>11.2.0</version>
   </dependency>

缺少jdbc.artifact.groupid的依赖项信息：jdbc-driver：jar：1.0
