我有一个包含以下条目的 WSDL 文件:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="urn:CP_Ablakido" xmlns:s0="urn:CP_Ablakido" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <wsdl:types>
    <xsd:schema elementFormDefault="qualified" targetNamespace="urn:CP_Ablakido">
      <xsd:element name="GetList_11" type="s0:InputMapping1"/>
      <xsd:complexType name="InputMapping1">
        <xsd:sequence>
          <xsd:element name="Qualification" type="xsd:string"/>
          <xsd:element name="startRecord" type="xsd:string"/>
          <xsd:element name="maxLimit" type="xsd:string"/>
        </xsd:sequence>
      </xsd:complexType>
      <xsd:element name="GetList_11Response" type="s0:OutputMapping1"/>
      <xsd:complexType name="OutputMapping1">
        <xsd:sequence>
          <xsd:element maxOccurs="unbounded" name="getListValues">
            <xsd:complexType>....

我使用具有以下设置的 CXF Codegen 插件:

<plugin>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-codegen-plugin</artifactId>
    <executions>
        <execution>
            <id>generate-sources</id>
            <phase>generate-sources</phase>
            <configuration>
                <sourceRoot>${basedir}/target/generated-sources/wsdl2java</sourceRoot>
                <encoding>UTF-8</encoding>
            </configuration>
            <goals>
                <goal>wsdl2java</goal>
            </goals>
        </execution>
    </executions>
</plugin>

生成的 java 代码如下所示:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "OutputMapping1", propOrder = {
    "getListValues"
})
public class OutputMapping1 {

    @XmlElement(required = true)
    protected List<OutputMapping1 .GetListValues> getListValues;

问题是这里缺少@XmlRootElement。还有另一个类似的问题，例如

1. maven-cxf-codegen-plugin using Jaxb binding to add inheritance for all generated classes
2. Annotating CXF (wsdl2java) generated package
3. externally create jaxb annotations for class

正如其他答案提到的，我可以放置绑定(bind)文件。 所以我创建了一个包含以下内容的绑定(bind)文件:

<jaxb:bindings
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:annox="http://annox.dev.java.net"
version="2.0">
        <jaxb:bindings node="//xsd:element[@name='GetList_11Response']">
            <annox:annotate target="class">
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="GetList_11Response"/>
          </annox:annotate>
        </jaxb:bindings>
</jaxb:bindings>

我已将以下 block 添加到 POM.XML:

<wsdlOptions>
    <wsdlOption>
        <wsdl>${basedir}/src/main/resources/wsdl/CP_Ablakido_1.wsdl</wsdl>
        <bindingFiles>                                       
            <bindingFile>${basedir}/src/main/resources/wsdl/CP_Ablakido_1.xjb
            </bindingFile>
        </bindingFiles>
    </wsdlOption>
</wsdlOptions>

之后我收到错误信息:

com.sun.istack.SAXParseException2; systemId: file:/Project/icp-integration/icpiCameI/src/main/resources/wsdl/CP_Ablakido_1.xjb; lineNumber: 9; columnNumber: 72; XPath evaluation of "//xs:element[@name='GetList_11Response']" results in empty target node

    at com.sun.tools.xjc.reader.internalizer.Internalizer.transform(Internalizer.java:146)

所以我不知道如何准确描述当 complexType 为 OutputMapping1 时，然后将 @XmlRootElement 放入名为“GetList_11Response”的 OutputMapping1.java 中。

最佳答案

我找到了解决方案。这很棘手，因为:

1. 必须处理 XSD 内嵌在 WSDL 中的问题。 (诀窍是 schemaLocation="CP_Ablakido_1.wsdl#types1"。它告诉 JAXB 在 WSDL 文件中使用节点。)
2. 必须配置 CXF 才能使用 XJC 插件 (annox)。

必须将以下片段添加到 POM.XML:

<wsdlOption>
    <wsdl>${basedir}/src/main/resources/wsdl/CP_Ablakido_1.wsdl</wsdl>
    <bindingFiles>
        <bindingFile>${basedir}/src/main/resources/wsdl/CP_Ablakido_1.xjb</bindingFile> 
    </bindingFiles>
    <extraargs><extraarg>-xjc-Xannotate</extraarg></extraargs>
</wsdlOption>

依赖项必须添加到插件中:

<dependency>
    <groupId>org.jvnet.jaxb2_commons</groupId>
    <artifactId>jaxb2-basics-annotate</artifactId>
    <version>0.6.0</version>
</dependency>   

<dependency>
    <groupId>org.apache.cxf.xjcplugins</groupId>
    <artifactId>cxf-xjc-ts</artifactId>
    <version>3.0.5</version>
</dependency>

XJB 文件:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings version="2.0" 
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    jaxb:extensionBindingPrefixes="annox xjc"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
    xmlns:annox="http://annox.dev.java.net"
    xmlns:inheritance="http://jaxb2-commons.dev.java.net/basic/inheritance">

  <jaxb:bindings schemaLocation="CP_Ablakido_1.wsdl#types1" node="/xs:schema"> 
       <jaxb:bindings node="//xs:complexType[@name='InputMapping1']">
            <annox:annotate target="class">
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="GetList_11"/>
          </annox:annotate>
      </jaxb:bindings>    
      <jaxb:bindings node="//xs:complexType[@name='OutputMapping1']">
            <annox:annotate target="class">
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="GetList_11Response"/>
          </annox:annotate>
      </jaxb:bindings>
   </jaxb:bindings>
</jaxb:bindings>

关于java - 我想在 CXF codegen 上添加 @XmlRoot 注释，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34239587/
