在Maven中從JAXB類型生成XSD模式？

我想基本上從我的模型類生成XSD架構使用Maven插件在JAXB中註釋。下面是我的POM相關代碼：在Maven中從JAXB類型生成XSD模式？

檢查相關的帖子。我認爲jaxb有兩個插件，其中一個比另一個（輕描淡寫）好得多。我認爲正確的在artifact-id中有「jaxb2」。 –

這裏的勝利：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>jaxb2-maven-plugin</artifactId> 
    <version>1.3.1</version> 
    <executions> 
     <execution> 
      <goals> 
       <goal>schemagen</goal> 
      </goals> 
      <phase>generate-resources</phase> 
      <configuration> 
       <includes> 
        <include>com/myproject/model/*.java</include> 
       </includes> 
       <outputDirectory>${project.build.directory}/schemas</outputDirectory> 
      </configuration> 
     </execution> 
    </executions> 
</plugin>

由於'schemagen'的功能正在被'javac'取代，那裏的方法是什麼？只需將javac與相應的標誌添加到目標中？ – mike

提高對Naftuli Tzvi Kay's answer，我發現它使用起來更加方便jaxb2-maven-plugin的當前版本2.2，如本示例中所示（因爲2.x版本需要稍微不同的配置）：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>jaxb2-maven-plugin</artifactId> 
    <version>2.2</version> 
    <executions> 
     <execution> 
      <goals> 
       <goal>schemagen</goal> 
      </goals> 
      <phase>generate-resources</phase> 
      <configuration> 
       <sources> 
        <source>src/main/java/com/foo/model/xml</source> 
       </sources> 
       <outputDirectory>${project.build.directory}/schemas</outputDirectory> 
      </configuration> 
     </execution> 
    </executions> 
</plugin>

查看plugin documentation瞭解更多詳情。
