Question

我正在尝试使用maven jaxb2插件生成类。但是我收到以下例外：

搜索之后，我开始知道wsdl中的2声明导致问题：

<s:element ref="s:schema"/>
<s:any/>

在其中一篇文章中，我发现如果我使用下面给定的行更改上面的2行，那么插件生成的文件没有任何问题：

<s:any  minOccurs="2" maxOccurs="2" />

以下是我正在使用的插件配置：

<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>com.abc</generatePackage>
                <schemas>
                    <schema>
                        <url>http://someIP/dummywsdl.asmx?wsdl</url>
                    </schema>
                </schemas>
            </configuration>
        </plugin>

有没有其他方法可以在不更改WSDL的情况下解决问题，因为这是一个客户端WSDL，我不想将它存储在我的本地进行上述更改。

您的架构似乎无效。所以不，除非你修正错误，否则XJC不会编译它。

作为一种解决方法，您可以创建架构的本地副本并修复此副本。您可以创建一个目录文件，该文件将“重写”全局URL http://someIP/dummywsdl.asmx?wsdl`` into your local dummywsdl.asmx_wsdl`：

REWRITE_SYSTEM "http://someIP/dummywsdl.asmx?wsdl" "dummywsdl.asmx_wsdl"
