我试图找到信息，但没有任何可用的信息。能帮忙吗？

我最近遇到了同样的错误 似乎发生这种情况是因为 wsimport 与 jaxb 的 2.1 和 2.2 版本相混淆。
我能够通过编辑项目 pom.xml 并在每个导入的wsdl的配置中添加<target>2.1</target>标记来正确生成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>
希望无论谁遇到这个问题都会有所帮助。

我根据您的问题假设您在Java 6上运行？因为Java 6包含旧版本的JAX-WS，所以如果要在Java 6上生成，编译和运行JAX-WS 2.2，则必须覆盖那些包含的API。正如Tex Killer上面提到的，你可以告诉wsimport生成JAX-WS 2.1对象和一切都应该正常工作（假设你有一个包含JAX-WS 2.1而不是2.0的Java 6 JRE）。如果你特别想为2.2生成，我可以通过将我的POM设置为以下内容来实现这一点（为简洁起见，我只包含了 build 元素）：

我认为您需要在POM中进行三项更改才能使其正常运行。我从这里得到的所有三个：http://jax-ws-commons.java.net/jaxws-maven-plugin/usage.html。首先，您可能需要像上面一样为jaxws插件添加其他依赖项。另请注意，您必须取消注释maven-compiler-plugin，但看起来您已正确设置了已批准的目录。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版本以满足您的需求。
除了这些之外，我还必须通过在＆lt; java-home＆gt;下放置JAXB和JAX-WS API（在POM中定义的相同API）的jar来更新正在启用Maven的JRE。 / LIB /认可。最后，确保您刚刚更新的JRE正在启动Maven构建。如果它仍然无法正常工作，请查看Maven构建的Eclipse运行配置，并确保它使用带有背书库的JRE。 （在我的情况下，运行配置使用的是与项目配置不同的JRE - 我更新了项目JRE，但没有更新运行配置使用的项目，我花了大约一天的时间来弄清楚为什么它仍然没有工作）。
那应该为你做的伎俩。如果你想对它有点了解，你可以更新运行配置以直接引用外部支持的lib，以防你不想修改你的JRE安装。
