【问题描述】：

我正在使用 Maven Spring 生成类

<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>

生成了类，但是当我尝试调用它们时，它们却失败了，因为

java.lang.Exception: Unexpected exception, expected<cz.project.common.exceptions.DataBoxException> but was<javax.xml.ws.WebServiceException>
Caused by: java.lang.ClassNotFoundException: com.sun.xml.internal.ws.spi.ProviderImpl

例如，我尝试向插件和 pom 添加各种依赖项

<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-ri</artifactId>
<version>2.3.1</version>                        
</dependency>

<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>rt</artifactId>
<version>2.3.2</version>
</dependency>

<dependency>
<groupId>com.sun.org.apache.xml.internal</groupId>
<artifactId>resolver</artifactId>
<version>20050927</version>
</dependency>

但没有任何帮助。我尝试了插件的 com.sun.xml.ws 和 org.codehaus.mojo 版本

插件的完整定义是

wsdl 文件可以在https://github.com/dfridrich/CzechDataBox/tree/master/Resources 找到（这是来自不同人的不同项目，但我使用的是相同的 wsdls。）并且解释了 bindig Why is Maven generating method with 5 parameters instead of one from wsdl?

我需要添加什么来解决缺少的参考？

【参考方案1】：

在 pom.xml 中添加新的依赖项

<dependency>
    <groupId>com.sun.xml.ws</groupId>
    <artifactId>jaxws-rt</artifactId>
    <version>2.3.3</version>
</dependency>

【讨论】：

我在插件中添加了这个 javax.xml.wsjaxws-api2.3.1 version> com.sun.xml.wsjaxws-tools2.3.1 解决它
