我正在尝试使用 jaxws maven 插件为我的 Web 服务客户端生成源代码并获得以下异常；

我最近遇到了同样的错误。
似乎这是因为wsimport与jaxb的2.1和2.2版本混淆了。

通过编辑项目pom.xml<target>2.1</target>并向每个导入的 wsdl 的配置添加标签，我能够正确生成 Web 服务源，如下所示：

<execution>
    <goals>
        <goal>wsimport</goal>
    </goals>
    <configuration>
        <wsdlFiles>
            <wsdlFile>path/to/file.wsdl</wsdlFile>
        </wsdlFiles>
        <wsdlLocation>http://path/to/webservice?wsdl</wsdlLocation>
        <staleFile>path/to/file.stale</staleFile>
        <target>2.1</target>
    </configuration>
    <id>wsimport-generate-WebServiceName</id>
    <phase>generate-sources</phase>
</execution>

希望它对遇到此问题的人有所帮助。

我根据您的问题推测您在 Java 6 上运行？因为 Java 6 包含旧版本的 JAX-WS，如果您想在 Java 6 上生成、编译和运行 JAX-WS 2.2，您必须覆盖这些包含的 API。正如 Tex Killer 上面提到的，您可以告诉 wsimport 生成JAX-WS 2.1 对象和一切都应该正常工作（假设您拥有包含 JAX-WS 2.1 而不是 2.0 的 Java 6 JRE 之一）。但是，如果您特别想为 2.2 生成，我可以通过将我的 POM 设置为以下内容来做到这一点（为简洁起见，我只包含了build元素）：

<build>
    <plugins>

                    <configuration>
                        <target>2.2</target>

我认为您需要在 POM 中进行三项更改才能使其正常工作。我从这里得到的所有三个：http: //jax-ws-commons.java.net/jaxws-maven-plugin/usage.html。首先，您可能需要像我上面那样为 jaxws 插件添加额外的依赖项。另请注意，您必须取消注释 maven-compiler-plugin，但您似乎已正确设置了认可的目录。第三，您需要添加 maven-dependency-plugin 的定义。您可能需要修改 JAXB 和 JAX-WS API 版本以满足您的需要。

除了这些之外，我还必须通过将 JAXB 和 JAX-WS API（在 POM 中定义的相同）的 jar 放在 <java-home>/lib/endorsed 下来更新启动 Maven 的 JRE。 . 最后，确保刚刚更新的 JRE 正在启动 Maven 构建。如果它仍然无法正常工作，请检查您的 Maven 构建的 Eclipse 运行配置，并确保它使用带有认可库的 JRE。（在我的情况下，运行配置使用的 JRE 与项目配置不同——我更新了项目 JRE，但没有更新运行配置使用的 JRE，我花了大约一天的时间才弄清楚为什么它仍然没有在职的）。

那应该对你有用。如果您想更了解它，您可以更新运行配置以直接引用外部认可的库，以防您不想修改 JRE 安装。

干杯
