Question

我刚接触到春季应用程序中的web服务，所以我在Spring guide网站上找到的教程中工作，并且它工作得很好，所以，因为我需要使用this wsdl定义的webservice我尝试过简单地更改插件配置中的url，因此，在我的pom.xml文件中，而不是

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.12.3</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <schemaLanguage>WSDL</schemaLanguage>
        <generatePackage>hello.wsdl</generatePackage>
        <schemas>
            <schema>
                <url>http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl</url>
            </schema>
        </schemas>
    </configuration>
</plugin>

这是教程中的确切代码，我得到了

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.13.1</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <schemaLanguage>WSDL</schemaLanguage>
        <generatePackage>listarPedimentos.wsdl</generatePackage>
        <specVersion>2.1.5</specVersion>
        <schemas>
            <schema>
                <url>https://201.175.25.245/ventanilla-ws-pedimentos/ListarPedimentosService?wsdl</url>
            </schema>
        </schemas>
    </configuration>
</plugin>

在进行一些研究时，我发现它可能是由jaxb2版本引起的问题，所以我把它改为0.13.1，后来我发现它可能是因为JAX-创建的web服务WS 2.1.5。并发现它可以通过添加来解决 2.1.5 到插件声明的配置部分，但它不起作用，我仍然得到相同的错误
