无法从wsdl文件生成Java代码

Question

首先，我使用Java创建了简单的Web服务，然后为该Web服务生成了wsdl，并使用SoapUI进行了测试，使其工作正常。 在那之后，现在我正尝试从先前生成的wsdl文件生成Java类。

这是我的pom.xml文件配置。

            </plugin>
        </plugins>

        </build>


    </project>

当我尝试生成它时，出现这样的错误。

    [ERROR] 

所以我没有低估这是什么5件事是什么？

更新 ：根据@Simze的回答，以上错误消失了。 现在我正在解决这个错误。

wsdl文件

Answer 1

终于找到了解决方案。 在为给定的wsdl文件生成Java代码时，我们需要在cxf-codegen-plugin的配置部分中指定要生成的内容

...
   <wsdlOptions>
    <wsdlOption>
        <wsdl>${basedir}/src/main/resources/OrderProcess.wsdl</wsdl>
        <extraargs>
            <extrrg>-impl</extrrg>
            <extrrg>-server</extrrg>
        </extraargs>
    </wsdlOption>
    </wsdlOptions>
 .....

在这里， -impl表示这将生成服务实现类，并且-server用于生成可用于公开服务的服务器组件。

因为您正在尝试在不支持注释的Java 1.3下运行Maven而遇到了错误。 请在<build>元素下添加以下标签，以解决您的问题。

<plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.0</version>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
      </configuration>
    </plugin>
</plugins>

Answer 3

您需要使用Java 1.5或更高版本。 这就是编译器错误告诉您的内容-源代码5，因为注释支持是从Java 1.5开始添加到Java的。
