IllegalAnnotationExceptions：兩個類具有相同的XML類型名稱。 CXF插件生成的代碼

Question

我有兩個WSDL，可使用maven cxf-codegen-plugin（org.apache.cxf）從中生成Java代碼。 它們都使用相同的名稱空間，並包含相同名稱的復雜類型，這就是為什么我遇到與Java類名稱沖突的問題的原因。 我決定使用bindings.xml解決它：

<jaxws:bindings
        xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
        xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
        xmlns="http://www.w3.org/2001/XMLSchema"
        version="2.1">
    <jaxws:bindings wsdlLocation="./TaskService_v1.wsdl" node="xsd:schema">
        <jaxb:schemaBindings>
            <jaxb:nameXmlTransform>
                <jaxb:typeName prefix="TaskService" />
                <jaxb:elementName prefix="TaskService" />
            </jaxb:nameXmlTransform>
        </jaxb:schemaBindings>
    </jaxws:bindings>
</jaxws:bindings>

例如，這將生成的類B2BParameter重命名為TaskServiceB2BParameter，因此我不再遇到名稱沖突的問題，但遇到了另一個問題：

Unknown JAXB exception; nested exception is com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 4 counts of IllegalAnnotationExceptions
Two classes have the same XML type name "{http://serviceinterface.b2b.adx.com}B2BParameter". Use @XmlType.name and @XmlType.namespace to assign different names to them.
this problem is related to the following location:
    at com.adx.b2b.serviceinterface.TaskServiceB2BParameter
this problem is related to the following location:
    at com.adx.b2b.serviceinterface.B2BParameter
    at protected java.util.List com.adx.b2b.serviceinterface.B2BRequest.parameter
    at com.adx.b2b.serviceinterface.B2BRequest
...

這是生成TaskServiceB2BParameter.java的：

package com.axd.b2b.serviceinterface_v1;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "B2BParameter", propOrder = {
    "name",
    "value"
})
public class TaskServiceB2BParameter {
    ...
}

如何更新我的bindings.xml以適當地更改@ XmlType.name？ 還是我真的需要更改目標軟件包？ 先感謝您！

問題在於，單個編組人員發現了具有相同元素名稱的類。 我這樣解決了這個問題：

1）將類生成到不同的包中

        <plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-codegen-plugin</artifactId>
            <version>3.3.3</version>
            <executions>
                <execution>
                    <id>generate-sources</id>
                    <phase>generate-sources</phase>
                    <configuration>
                        <sourceRoot>${project.build.directory}/generated-sources/cxf</sourceRoot>
                        <wsdlOptions>
                            <wsdlOption>
                                <wsdl>${basedir}/src/main/resources/META-INF/wsdl/Service1.xml</wsdl>
                                <packagenames>
                                    <packagename>com.xxx.service1</packagename>
                                </packagenames>
                            </wsdlOption>
                            <wsdlOption>
                                <wsdl>${basedir}/src/main/resources/META-INF/wsdl/Service2.xml</wsdl>
                                <packagenames>
                                    <packagename>com.xxx.service2</packagename>
                                </packagenames>
                            </wsdlOption>
                        </wsdlOptions>
                    </configuration>
                    <goals>
                        <goal>wsdl2java</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

2）為每個服務創建特殊的marshaller bean

@Configuration
public class WebServiceConfig {

@Bean
public Jaxb2Marshaller service1Marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.xxx.service1");
    return marshaller;
}

@Bean
public Jaxb2Marshaller service2Marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("com.xxx.service2");
    return marshaller;
}
}
