jaxb2 - 在使用 maven-jaxb2-plugin 时，在整个编译中只允许一个 globalBindings 自定义出现错误

Question

我正在使用 maven-jaxb2-plugin。这是我的插件配置

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <executions>
        <execution>
            <id>xjc-serviceoperations</id>

            </configuration>
        </execution>
    </executions>
</plugin>

这是我的 schema-binding.xml 文件

<?xml version="1.0" encoding="UTF-8"?>

        <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 都转换为 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

这是我的 schema-binding.xjb

现在当我跑步时Run As -> Maven generate-sources。它将在中生成服务操作源并在中src/main/java/com/..../serviceoperation/customer/AddCustomerRequest.java键入源src/main/java/com/.../types/customer/Customers.java。其他xsds类似。

为什么我不应该使用<generateDirectory>${basedir}/src/main/java/</generateDirectory>. 这就是我要的。我认为这个插件正在从每个 xsd 中的 targetnamespace 制作包。我对吗？

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

我希望我在 serviceoperations 文件夹中的所有 xsd 都应该在,文件夹(src/main/resources/schemas/lmsapi/serviceoperation/*.xsd)中生成，其他人也一样。src/main/java/com/..../serviceoperation/customer/*.javasrc/main/java/com/..../serviceoperation/enrollment/*.java

中的所有 xsds都应在、文件夹中(src/main/resources/schemas/lmsapi/types/*.xsd)生成，其他的也应相同。src/main/java/com/..../types/customer/*.javasrc/main/java/com/..../types/enrollment/*.java

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

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...

此问题随机出现，是由 JAXB 实现中的错误引起的。该问题已报告JAXB-687，但它现在已关闭，即使它尚未修复（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.

或者删除xjc:serializable uid="1"也有效。
