获取错误 在使用 maven-jaxb2-plugin 时，在整个编译中只允许一个全局绑定自定义



我正在使用maven-jaxb2-plugin。这是我的插件配置

这是我的架构绑定.xml文件

        <xjc:serializable uid="1" /> 
    </jaxb:globalBindings>
</jaxb:bindings>

我有一个 xsd Enrollments.xsd.其中我有日期类型。我希望任何具有日期或日期时间类型的xsd转换为Localdate或Localdatetime而不是XMLGregorianCalendar。这是片段

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://enrollment.types.lmsapi.message.webservice.lms.vu360.softech.com"
    xmlns="http://enrollment.types.lmsapi.message.webservice.lms.vu360.softech.com" 
    elementFormDefault="qualified"
    attributeFormDefault="unqualified">
    <xsd:include schemaLocation="Learner.xsd"/>
    ...
    <xsd:complexType name="LearnerEnrollCourses">  
        <xsd:sequence>  
            <xsd:element name="CourseId" type="xsd:string" minOccurs="1" maxOccurs="unbounded" nillable="false"  />
        </xsd:sequence> 
        <xsd:attribute name="enrollmentStartDate" type="xsd:date" use="required" />
         <xsd:attribute name="enrollmentEndDate" type="xsd:date" use="required" /> 
    </xsd:complexType>
    ...
</xsd:schema>

现在，当我右键单击POM时，选择Run As -> Maven generate-sources然后我收到以下错误

[INFO] Sources are not up-to-date, XJC will be executed.
[ERROR] Error while parsing schema(s).Location [ file:/D:/Basit/eclipse-jee-mars-2/workspace/360Training/Java%208/LS360ProxyAPI/LmsApiProxy/src/main/resources/schemas/schema-binding.xjb{12,26}].

虽然类正在生成。但类型仍然是 XMLGregorianCalendar。

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "LearnerEnrollCourses", propOrder = {
    "courseId"
})
public class LearnerEnrollCourses {
    @XmlElement(name = "CourseId", required = true)
    protected List<String> courseId;
    @XmlAttribute(name = "enrollmentStartDate", required = true)
    @XmlSchemaType(name = "date")
    protected XMLGregorianCalendar enrollmentStartDate;
    @XmlAttribute(name = "enrollmentEndDate", required = true)
    @XmlSchemaType(name = "date")
    protected XMLGregorianCalendar enrollmentEndDate;

我在配置中做错了什么，我该如何解决？

谢谢

            ....
        </xsd:sequence>  
    </xsd:complexType>
    ...
</xsd:schema>

现在当我运行Run As -> Maven generate-sources.它将在src/main/java/com/..../serviceoperation/customer/AddCustomerRequest.java中生成服务操作源，并在src/main/java/com/.../types/customer/Customers.java中键入源。其他 xsd 类似。

为什么我不应该使用<generateDirectory>${basedir}/src/main/java/</generateDirectory>.这就是我想要的。我认为这个插件正在从每个 xsd 中的目标命名空间制作包。我说的对吗？

如果我在配置此插件时做错了什么，请告诉我，以便我纠正它。就像你说的不要在 src/main/java 中生成。

我希望我在服务操作文件夹中的所有 xsds (src/main/resources/schemas/lmsapi/serviceoperation/*.xsd)应该在 src/main/java/com/..../serviceoperation/customer/*.java 、src/main/java/com/..../serviceoperation/enrollment/*.java 文件夹中生成，并且对其他人也是如此。

(src/main/resources/schemas/lmsapi/types/*.xsd)中的所有 xsds 都应在 src/main/java/com/..../types/customer/*.java 、src/main/java/com/..../types/enrollment/*.java文件夹中生成，其他文件夹也是如此。

而且我的绑定文件也适用于所有 xsds (src/main/resources/schemas/schema-binding.xjb) servieoperations 和 types 文件夹中的所有 xsds。

有没有更好的方法来配置这个插件，然后请告诉我，以便我可以在我这边更正它。我猜你是这个插件的作者。

感谢和问候

该问题

的当前状态，以免其他人感到沮丧和搜索...

此问题是随机出现的，是由 JAXB 实现中的错误引起的。该问题已报告JAXB-687，但是即使它尚未修复，它现在已关闭（请参阅2016年9月16日发布的次优用户的评论）。

有类似的问题，并通过更改java version from 1.8 -> 1.7来解决它。

或者，删除xjc:serializable uid="1"也有效。
