maven - 无法使用 Maven 从 XSD 文件生成源文件？

标签 maven soap wsdl soap-client maven-jaxb2-plugin

我有这个wsdl schema .我需要从该 WSDL 模式生成源代码文件。我尝试了许多不同的东西，但无法生成 Java stub 。在这篇文章中，我将尝试仅概述我采用的最后一种也是最相关的方法。另外，我会指出我的怀疑可能是问题所在，我会发布我收到的控制台错误。有指向 GitHub repo 的链接(这是一个简单的 Maven 项目，在 Spring Tools Suite 中，只有一个入门类，没有任何设置。我使用的是 Java 1.8)。
联系方式
我的第一次尝试是使用 SOAP UI工具，并从上面的链接生成*.xsd使用该工具的文件。成功创建这些文件后，我将它们放在 src/main/resources/arvatoprod Maven 项目中的文件夹。然后我创建了 pom.xml (省略不相关的依赖项)在 Maven 项目中。

    <build>
        <finalName>Fleaty</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>

                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <generatePackage>com.zesium.arvato</generatePackage>
                    <schemaDirectory>src/main/resources/arvatoprod</schemaDirectory>
                    <schemaIncludes>
                        <include>*.xsd</include>
                    </schemaIncludes>
                </configuration>
            </plugin>
        </plugins>
    </build>
在此之前，我确实像往常一样，做了Maven-clean命令。我从控制台收到的消息，在 Maven generate-sources 之后命令如下(我将粘贴整个消息并解释我对关键行的看法):

我不确定这条消息应该告诉我什么。无论如何，我已经尝试删除文件夹 2.3.0在位置 /C:/Users/Miljan/.m2/repository/org/glassfish/jaxb/jaxb-runtime/因为在那个位置我有一堆其他版本/文件夹2.3.1 , 2.3.4 .每次点击Maven generate-sources ，那个文件夹2.3.0再次出现。该文件夹的内容可以在下面的图像中找到:

和

所以wsimport工具(可能 jax2b-maven-plugin 使用它来生成 stub )无法构建这些 Java 类，因为存在某种命名错误。如果我是正确的，本质上这是编译错误，出于某种原因wsimport工具(或插件)无法解决它。
我不懒，所以我打开了xsd错误中提到的文件，AFSService_1.xsd .这就是行 328和 377看起来像:
专线 328 :
  <xs:element minOccurs="0" name="AccountInfo" nillable="true" type="tns:AFSInvoiceAccountInfo"/>
专线 377 :
  <xs:element name="AFSInvoiceAccountInfo" nillable="true" type="tns:AFSInvoiceAccountInfo"/>
我做了我的研究，人们在做什么叫做 binding (docs)。本质上，可以更改方法、数据类型等的命名。现在，我对 XSD 不是很精通。 , WSDL s 并且通常使用 JAXB建筑学。我确实知道基本术语(什么是 xml namespaces ， xsd schemas ，什么是 SAX 和 DOM 解析器， XPath ， XQuery ，我用过所有这些)。
我不确定我是否应该编写这些绑定(bind)，这是我要采取的最后一步，还是我只需要在我的机器/项目上配置一些东西来制作这些 stub ？

最佳答案

感谢您在问题中提供完整图片!
以下答案几乎就是这里给出的答案:https://stackoverflow.com/a/13438253/618156
该问题主要是由于 XJC 遇到 AccountInfo 问题。和 AFSInvoiceAccountInfo (根据上面链接的答案)。
因此，似乎需要手动识别它们:
您需要以下 bindings.xjb文件在 src/main/resources (将由 maven-xjb2-plugin 自动找到):

<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
               xmlns:xs="http://www.w3.org/2001/XMLSchema"
               version="1.0">
    <jaxb:bindings schemaLocation="https://clienttesthorizon.horizonafs.com/AFSServices/AFSService.svc?xsd=xsd2">
        <jaxb:bindings node="//xs:element[@name='AFSInvoiceAccountInfo']">
            <jaxb:factoryMethod name="AFSInvoiceAccountInfo"/>
        </jaxb:bindings>
        <jaxb:bindings node="//xs:element[@name='AccountInfo']">
            <jaxb:factoryMethod name="AccountInfo"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>
...对于我来说，maven-xjb2-plugin 的以下配置对我有用在您的 pom.xml (删除了我认为对我的测试不必要的所有内容，它与您最初在问题中发布的内容非常接近):
<project...>
    <!-- ... -->
    <build>
        <plugins>
            <plugin>
                <groupId>org.jvnet.jaxb2.maven2</groupId>
                <artifactId>maven-jaxb2-plugin</artifactId>

                        <schema>
