Xsd 如何强制生成@XmlSeeAllow注释？

我正在使用JAXB从几个XSD文件生成Java代码。然后，在OSGi容器中，我将XML文件解组到生成的代码中。XSD使用XSD:any元素：

<xsd:complexType name="GetReservationRSType">
    <xsd:sequence>
        <xsd:element name="Errors" type="pnrb:Errors.PNRB"
            minOccurs="0" />
        <xsd:choice>
            <xsd:element name="Reservation" type="pnrb:Reservation.PNRB"
                minOccurs="0" />
            <xsd:element name="Content" minOccurs="0">
                <xsd:complexType>
                    <xsd:choice>
                        <xsd:any processContents="lax" />
                    </xsd:choice>
                </xsd:complexType>
            </xsd:element>
        </xsd:choice>
    </xsd:sequence>
</xsd:complexType>

有没有办法强迫JAXB自动添加这样的注释？例如，通过添加一些JAXB绑定配置选项或修改XSD文件

编辑：

OSGi env中的我的JAXBContext是通过以下方式初始化的（它获取所有生成的包名作为参数）-它们与冒号分隔符的用法一起列出，正如在一些与JAXB相关的文章中所建议的那样：

<bean id="jaxbContext" class="javax.xml.bind.JAXBContext" factory-method="newInstance">
    <constructor-arg index="0" value="com.sabre.webservices.pnrbuilder:com.sabre.webservices.sabrexml._2003._07" />    
</bean>

您应该在生成的包名上创建

JAXBContext

，而不是试图强制输入

@xmlseea

注释。通过这种方式，您可以确保所有类都已处理。由于您处于OSGi环境中，因此可以使用其中一种方法来获取

ClassLoader

参数

JAXBContext jc = JAXBContext.newInstance("com.example.foo", ObjectFactory.class.getClassLoader());

如果有多个生成的包名，则上下文路径是分隔的

JAXBContext jc = JAXBContext.newInstance("com.example.foo:org.example.bar", ObjectFactory.class.getClassLoader());

我找到了一个令人满意的解决办法。它使用。也许这不是一个完美的解决方案，但至少它阻止了我将生成的类提交到SVN存储库中。 提到的插件只是添加了想要的注释

以下是pom.xml中所需的配置：

jaxb2基础注释

所需的注释在bindings.xjb文件中配置，该文件应与*.xsd文件位于同一目录中-其内容如下：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
                xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"

            </annox:annotate>           
        </bindings>

    </bindings>    
</bindings>

AFAIK jaxb在模式中有扩展时也会生成@xmlsee。

ClassLoader

参数非常重要。您发布了什么类型的配置文件？这是标准的springbeans.xml文件。jaxbcontextbean然后被注入到另一个实际上负责解组的bean中。@LukaszBaran-我似乎找不到允许您指定

类加载器的Spring属性。我怀疑Spring在创建
JAXBContext
时没有包含一个。相反，您可以在Springs要绑定的类列表中包含要引用的类。
@xmlseea
。好吧，我刚刚尝试完全按照您的建议在Java代码中初始化JaxbContext-不幸的是，我一直得到相同的异常。@LukaszBaran-听起来这更像是Spring的问题，而不是JAXB的问题。
