java - wsdl2java 两个类具有相同的 XML 类型名称 "{http://***.***.***.***/***/***/***}objectFactory"

Question

此问题发生在较新版本的 servicemix(在 5.4 - cxf 3.0.2 和 5.3 - cxf 2.7.11 上测试)在旧版本 4.5.2 和 cxf 2.6.8 一切正常，创建了 web 服务。

在我们的项目中，我们有很多不同的包中的 maven 插件 wsdl2java 生成的不同的 web 服务。在 servicemix 5.4 中，几乎所有的 web 服务都由于这些错误而关闭，奇怪的是，在以前的 servicemix 5.3 中，其中一个 bundle 无需对项目进行任何修改即可启动。

在 maven 中我尝试使用额外的 extraarg:

<extraarg>-autoNameResolution</extraarg>
<extraarg>-xjc-npa</extraarg>

但没有任何结果

我试图将 cxf 降级到 2.6.8，但我得到了同样的错误，所以我想问题出在其他地方，可能在 org.apache.aries.blueprint.core 中。

我也尝试用所有生成的类创建一个大包，但问题是一样的

如果您通过 cxf-codegen-plugin 生成 ws-client 代码，您可以使用具体配置。我在我的一个项目中取得了类似的成就:

 ...
 <plugin>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-codegen-plugin</artifactId>
        <version>${cxf.version}</version>
        <executions>
            <execution>
                <id>generate-sources</id>
                <phase>generate-sources</phase>
                <configuration>
                    <sourceRoot>${basedir}/src/main/gen</sourceRoot>
                    <wsdlOptions>
                        <wsdlOption>
                            <wsdl>${basedir}/src/main/resources/MyWSEndpoint1.wsdl</wsdl>
                            <extraargs>
                                <extraarg>-client</extraarg>
                                <!--
                                <extraarg>-validate</extraarg>
                                -->
                                <extraarg>-p</extraarg>
                                <extraarg>com.acme.ws.jaxb.ns1</extraarg>
                                <extraarg>-wsdlLocation</extraarg>
                                <extraarg></extraarg>
                            </extraargs>
                        </wsdlOption>
                        <wsdlOption>
                            <wsdl>${basedir}/src/main/resources/MyWSEndpoint2.wsdl</wsdl>
                            <extraargs>
                                <extraarg>-client</extraarg>
                                <!--
                                <extraarg>-validate</extraarg>
                                -->
                                <extraarg>-p</extraarg>
                                <extraarg>com.acme.ws.jaxb.ns2</extraarg>
                                <extraarg>-wsdlLocation</extraarg>
                                <extraarg></extraarg>
                            </extraargs>
                        </wsdlOption>
                    </wsdlOptions>
                </configuration>
                <goals>
                    <goal>wsdl2java</goal>
                </goals>
            </execution>
        </executions>
 </plugin>          
 ...    

因此，每个 ws-client 特定的“个人”包 {http://***.***.***.***/***/***/*** }objectFactory 应该生成，这可能有助于避免代码生成阶段的冲突。因此，在运行时，不会有与 namespace 相关的问题阻碍您。

请记住，com.acme.ws.jaxb.ns1 和 com.acme.ws.jaxb.ns2 只是建议，您可以使用任何看似对您在那里的项目有效。

另见 Apache CXF - WSDL to Java

-p [ wsdl-namespace= ] PackageName

Specifies zero, or more, package names to use for the generated code. Optionally > specifies the WSDL namespace to package name mapping.
