如何更新JDK中使用的JAXB版本？

Question

当我用JDK 8编译我的XSD时，我得到了我期望的输出。

当我用JDK 7编译XSD时，它似乎没有读取我的binding.xjb文件。

我敢肯定，这是jaxb-v2之间的许多缺陷之一。

• JDK7第一版JAXB 2.2.4-1
• JDK8第一版JAXB 2.2.8

发布说明：JAXB

有人能帮助我，如果可能的话，如何更新JDK使用的JAXB版本吗？

我正在使用Maven构建并使用.的依赖关系。

  <dependency>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics-runtime</artifactId>
    <version>0.6.4</version>

我用的插件是..。

我可能走错路了，也许我需要看看org.jvnet.jaxb2.maven2:maven-jaxb2-plugin

这显示了JDK和JDK 8运行之间的区别。在左边，它似乎忽略了binding.xjc文件，因此不知道枚举的大小。

​

我们还可以看到，生成的java类具有不同的类型。

​

另外，它在JDK 8中生成Adapter类，而在JDK 7中不生成Adapter类。

很少有建议：

1. args在两个位置定义。一个在/plugin/executions/execution/configuration/args下，一个在/plugin/configuration/args下。你可以把它放在/plugin/configuration/args里。
2. 在/plugin/配置下，有两个属性schemaDirectory和bindingDirectory.在上面的插件使用中，xsd和xjb是否都位于资源目录中？
3. 您是否也可以尝试设置这些参数：forceRegenerate=true和cleanPackageDirectories=false.

只要提到一个例子插件定义作为参考，你可以修剪你不需要的细节。
