java - 使用 axis2 和 Maven 的 Web 服务

Question

我必须使用 axis2 和 Maven 在 Eclipse 中创建一个 Web 服务，但我有很多问题。这是pom.xml:

Eclipse 给我这个错误:描述资源路径位置类型生命周期配置未涵盖插件执行:org.apache.axis2:axis2-java2wsdl-maven-plugin:1.5.4:java2wsdl (execution:default,phase:process-classes) pom.xml/MavenAxis2WS line 20 Maven Project Build Lifecycle Mapping问题

如果我在命令行 mvn package 和 mvn process-classes 上写入，eclipse 会生成 wsdl 文件，但它是空的。我无法创建网络服务。请帮我。我需要一个完整的示例，其中完整描述了每个步骤。我需要使用以下文件夹创建一个项目:src/main/java。我希望有人能帮助我!!

谢谢!!!

编辑:

如果我删除进程类，则会出现此错误:描述资源路径位置类型生命周期配置未涵盖插件执行:org.apache.axis2:axis2-java2wsdl-maven-plugin:1.5.4:java2wsdl (execution:default,phase:process-classes) pom.xml/MavenAxis2WS line 20 Maven Project Build Lifecycle Mapping问题。如果我删除

<execution>
        <goals>
          <goal>java2wsdl</goal>
        </goals>
      </execution>
    </executions> 

我没有任何错误，但当我运行 mvn package 或 mvn process-classes 时，Eclipse 不会创建 wsdl。

MavenAxis2WebService 类是:

package com.ratra.ws.MavenAxis2WS;
public class MavenAxis2WebService {
  public String ping(String text) {
    if (text == null) {
      return "Service is up and available";
    }
    return "Service is up and available, message: " + text;
  }
}

当我尝试运行 http://localhost:8080/MavenAxis2WS/services/MavenAxis2WebService?wsdl 时获得HTTP 状态 500 - javax.servlet.ServletException:org.apache.axis2.deployment.DeploymentException:org/apache/commons/httpclient/HttpException。我发布 web.xml

</web-app>

Answer 1

在此博客上，您可以学习如何制作客户端部分，以便您拥有 wsdl 并尝试与现有服务器进行通信 http://briansjavablog.blogspot.fr/2013/01/axis2-web-service-client-tutorial.html .

在这一点上，你什么都没有，你就是服务器http://sunnyratra.me/tag/apache-axis2-maven-example/

有简单但完整的示例，希望对您有所帮助
