使用maven从java生成WSDL：CXF + java2ws目标

时间：2011-11-22 10:29:59

标签： java web-services maven wsdl cxf

是否有一个可理解的教程，展示了如何使用maven和cxf目标java2ws从java代码生成WSDL？

我想在包含mvn install注释类的项目上执行@WebService，并在目标文件夹中的某处生成WSDL，以便其他开发人员可以使用它来生成订阅者类。

此外，我希望将Webservice包含在我可以在WebService容器内部署的jar中，以便该订阅服务可用。

到目前为止，我的pom看起来像这样：

<properties>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <cxf.version>2.2.3</cxf.version>
</properties>

但是当我运行maven install ..没有wsdl ..

哦，对，其他信息：我们正在以模块化的方式进行开发。提供WebService的模块将包含其他类，这些类处理来自前端模块的内部方法调用，并将构建为jar而不是war。

希望有人找到我所缺少的东西，或者能指出一个好的教程。

修改 直接使用mvn org.apache.cxf:cxf-java2ws-plugin:java2ws调用了目标，但我得到了LifecycleExecutionException：

然而，如上所示，className参数存在且路径也是正确的......任何想法？

标签<pluginManagement>看起来未知。如果我删除它（并更新到cxf版本2.5），即使只是.jar包装，一切都很好。

不知道为什么在网络上随处可见标签。还想知道为什么maven没有检测到或记录这些错误。叹息...

仅适用于那些与pluginManagement无关的麻烦的人。就我而言，对于cxf.version 3.1.10，问题在于放置<configuration>部分。将它移动到与<executions>相同的水平后，问题就消失了。我在这里找到了它：http://cxf.547215.n5.nabble.com/Strange-behavior-of-Maven-cxf-java2ws-plugin-td553742.html

以下是apache.org（https://cxf.apache.org/docs/maven-java2ws-plugin.html）的示例：

<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-java2ws-plugin</artifactId>
<version>${cxf.version}</version>
<dependencies>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf.version}</version>
    </dependency>
</dependencies>

<executions>
    <execution>
        <id>process-classes</id>
        <phase>process-classes</phase>
        <configuration>
            <className>full.class.name</className>
            <genWsdl>true</genWsdl>
            <verbose>true</verbose>
        </configuration>
        <goals>
            <goal>java2ws</goal>
        </goals>
    </execution>
</executions>
</plugin>

这里有一个固定的：

<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-java2ws-plugin</artifactId>
<version>${cxf.version}</version>
<dependencies>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>${cxf.version}</version>
    </dependency>      
</dependencies>

<configuration>
    <className>full.class.name</className>
    <genWsdl>true</genWsdl>
    <verbose>true</verbose>
</configuration> 

<executions>
    <execution>
        <id>process-classes</id>
        <phase>process-classes</phase>
        <goals>
            <goal>java2ws</goal>
        </goals>
    </execution>
</executions>
</plugin>
