我正在使用 jax-ws 的 wsimport 从 WSDL 生成 java 类。我正在使用 jaxb2-basics 插件来创建 toString、equals、hashCode、复制和合并方法。
如果我们需要更改它，我希望生成的类实现接口以将我们的代码与实现隔离。
我想使用 jaxb2 的能力来生成实现指定接口的类，但成功率有限。类实现接口是不够的。我希望由其他生成的类组成的生成类在引用这些对象时使用接口而不是实现。
我正在使用一个外部绑定文件来定义一个类应该实现的接口：
<jaxws:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
xmlns:s="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
wsdlLocation="ExampleService.wsdl"
xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance"
jaxb:extensionBindingPrefixes="inheritance">
<!-- Person -->
<jaxws:bindings node="wsdl:definitions/wsdl:types/s:schema[@targetNamespace='http://example.com/ws']">
<jaxb:bindings node="//s:complexType[@name='Person']">
<inheritance:implements>com.example.IPerson</inheritance:implements>
</jaxb:bindings>
</jaxws:bindings>
<!-- Bus -->
<jaxws:bindings node="wsdl:definitions/wsdl:types/s:schema[@targetNamespace='http://example.com/ws']">
<jaxb:bindings node="//s:complexType[@name='Bus']">
<inheritance:implements>com.example.IBus</inheritance:implements>
<jaxb:bindings node="//s:element[@name='Driver']">
<jaxb:class ref="com.example.IPerson"/>
</jaxb:bindings>
<!-- How to do this? This doesn't work.
<jaxb:bindings node="//s:element[@name='Passengers']">
<jaxb:class ref="java.util.List<com.example.IPerson>"/>
</jaxb:bindings>
-->
</jaxb:bindings>
</jaxws:bindings>
例如，如果我有一个名为 Bus 的类，其中有一个名为 Person 的类，我希望 Bus 实现 IBus，Person 实现 IPerson，并且 Bus 有一个 IPerson 类型的成员变量，而不是 Person。
public Class Bus implements IBus {
protected IPerson driver;
...
}
我在绑定文件中的内容正在工作。
但是，如果 Bus 有一个 Person 对象列表，我无法让 wsimport 为 Bus 生成一个定义 IPerson 对象列表的类。
public Class Bus implements IBus {
protected IPerson driver;
protected List<IPerson> passengers;
...
}
这是我使用的示例 wsdl（愚蠢而愚蠢的示例，但它明白了重点）：

有谁知道是否可以让 jaxb2-basics 生成一个通用对象，其类型变量在 jaxb 绑定文件中指定？
