编译 WSDL 文件时出现错误/警告 - 但生成的 Java 源代码正常 -Java17 spring boot 3.0

Question

我的要求 spring boot 3.0 Java 17。我的代码使用 jaxb2 插件适用于 java 1.8 spring boot 2.7.11。我已将插件更新为 jaxb30-maven-plugin。自动生成的java代码就可以了。构建成功。但在构建控制台中我们可以发现以下错误。

[错误]解析模式时出错。Location [ file:.wsdl{11,51}].org.xml.sax.SAXParseException：s4s-elt-schema-ns：元素“definitions”的命名空间必须是来自模式命名空间“http://www.w3.org/2001/XMLSchema”

Error:

我也遇到过类似的问题并找到了解决方案。似乎在某些情况下，XJC 处理器应该注意到它解析 WSDL 而不是简单的模式。只需在您的插件配置中设置它即可：

        <plugin>
            <groupId>com.evolvedbinary.maven.jvnet</groupId>
            <artifactId>jaxb30-maven-plugin</artifactId>
            <version>0.15.0</version>
            ...
            <configuration>
                ...
                <schemaLanguage>wsdl</schemaLanguage>
            </configuration>
        </plugin>
