Axis ClassNotFoundException

标签： java web-services soap axis

当我尝试使用Axis webservice返回自定义对象时收到以下错误：

    aug 22, 2017 12:11:52 PM org.apache.axis.deployment.wsdd.WSDDService deployTypeMapping
SEVERE: Unable to deploy typemapping: {http://server}Case
java.lang.ClassNotFoundException: server._case
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1269)
    at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1104)
    at org.apache.axis.utils.ClassUtils$2.run(ClassUtils.java:187)

似乎web服务无法找到我的Case类，但它在wsdl中定义。

这是我的代码： 情况下：

package server;

import java.io.Serializable;

public class Case implements Serializable {

    private static final long serialVersionUID = -1549174508068625157L;
    private String id;

    public Case() {

    }

    public Case(String id) {
        this.id = id;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

}

CaseServiceImpl：

package server;

public class CaseServiceImpl implements CaseService {

    //This one works
    @Override
    public String hello(String message) {
        return message;
    }

    //This one doesn't show up
    @Override
    public Case test() {
        return new Case("TR-1");
    }

}

CaseServiceImpl.wsdl（自动生成）：

我觉得我错过了一些东西，但我不知道是什么。有人能指出我正确的方向吗？

2 个答案:

答案 0 :(得分：0)

显然我不能在我的课程中使用Case这个名称，因为case被保留了，并且在某些时候它会被资本化。重命名课程后，它可以工作。

答案 1 :(得分：0)

您似乎已找到问题的解决方案，但我会为潜在读者发布详细步骤。希望它也有助于改进您的解决方案，因为我不确定您的问题不在于实体的命名。

<强>前提条件：

  1. Ant已安装
  2. Axis2已下载且AXIS_HOME环境变量已正确完成 在环境变量中设置
  3. 任何应用程序都可用于部署轴。在我的例子中，我使用了Tomcat Apache Tomcat/7.0.41。要部署轴，只需将以前下载的轴文件夹添加到TOMCAT_HOME\webapps文件夹中。

    4. 我使用了相同的bean和服务实现。所以：

    <强> Case.java 

    package server;

import java.io.Serializable;

public class Case implements Serializable {

    private static final long serialVersionUID = -1549174508068625157L;
    private String id;

    public Case() {
    }

    public Case(String id) {
        this.id = id;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

    <强> CaseService.java 

    package server;

interface CaseService {
    String hello(String message);
    Case test();
}

    <强> CaseServiceImpl.java 

    package server;

public class CaseServiceImpl implements CaseService { 
    //This one works
    @Override
    public String hello(String message) {
        return message;
    }

    //This one doesn't show up
    @Override
    public Case test() {
        return new Case("TR-1");
    }
}

    创建此基础结构后，您可以根据服务界面生成wsdl。转到比存储编译文件的文件夹高一级（Case.class，CaseService.class，CaseServiceImpl.class）。在我们的例子中，这是： enter image description here

    并运行以下命令：

    %AXIS2_HOME%\bin\java2wsdl.bat -cp . -cn server.CaseService -of CaseService.wsdl

    结果如下： enter image description here

    将创建新文件CaseService.wsdl。

        </wsdl:port>
    </wsdl:service>
</wsdl:definitions>

    现在我们已准备好生成WS组件。从生成CaseService.wsdl的文件夹中执行以下命令：

    %AXIS2_HOME%\bin\WSDL2Java -uri CaseService.wsdl -d adb -s -ss -sd -ssi -o service

    结果如下： enter image description here

    将生成新文件夹service。此命令还为您的WS方法生成一个框架，该框架应该被实现。因此，请打开CaseServiceSkeleton.java并实施hello和test方法。结果应该是这样的：

    package server;

public class CaseServiceSkeleton implements CaseServiceSkeletonInterface {
    public HelloResponse hello(Hello hello0) {
        CaseService caseService = new CaseServiceImpl();
        String hello = caseService.hello(hello0.getArgs0());

        HelloResponse helloResponse = new HelloResponse();
        helloResponse.set_return(hello);
        return helloResponse;
    }

    public TestResponse test(Test test2) {
        CaseService caseService = new CaseServiceImpl();
        Case test = caseService.test();
        server.xsd.Case aCase = new server.xsd.Case();
        aCase.setId(test.getId());
        TestResponse testResponse = new TestResponse();
        testResponse.set_return(aCase);
        return testResponse;
    }
}

    由于您依赖CaseService，CaseServiceImpl和Case（在步骤＃1中生成），请将这些文件复制到生成CaseServiceSkeleton.java的同一文件夹中。 现在您已准备好生成*.aar文件。它将用于WS部署。导航到新生成的service文件夹并执行ant命令：

    ant -buildfile build.xml

    结果如下： enter image description here

    将在build\lib\文件夹中创建CaseService.aar。 由于某种原因Test.class未自动包含在*.aar文件中，因此需要手动添加 - 只需将Test.class从build/classes文件夹复制到新生成的{{1}到CaseService.aar文件夹。完成所有这些步骤后，server文件夹应如下所示： enter image description here

    现在您可以将其部署到轴 - 只需将其复制到轴Web应用程序中的CaseService.aar\server即可。应该出现一个启动应用程序服务器的新服务。转到WEB-INF\services\。如果部署成功，则应显示以下页面： enter image description here

    服务调用

    如何使用提供的服务有很多方法。在我们的例子中，我们将使用生成的客户端存根。要生成客户端，请使用wsdl文件夹中的以下命令：

    http://your_host:your_port/axis_application_name/services/listServices

    结果如下： enter image description here

    此命令将生成包含两个文件的src文件夹：%AXIS2_HOME%\bin\WSDL2Java -uri CaseService.wsdl -d adb –o client 和CaseServiceStub.java。客户端应用程序将使用这些文件。 现在我们已准备好创建客户端应用程序本身：

    <强> Client.java 

    CaseServiceCallbackHandler.java

    在创建package client; import org.apache.axis2.AxisFault; public class Client { public static void main(String... args) { try { CaseServiceStub stub = new CaseServiceStub("http://localhost:8080/axis/services/CaseService"); invokeHelloMethod(stub); invokeTestMethod(stub); } catch (AxisFault axisFault) { axisFault.printStackTrace(); } } public static void invokeHelloMethod(CaseServiceStub stub) { try { CaseServiceStub.Hello request = new CaseServiceStub.Hello(); request.setArgs0("Hello World"); CaseServiceStub.HelloResponse response = stub.hello(request); System.out.println("Hello method says: " + response.get_return()); } catch (java.rmi.RemoteException e) { e.printStackTrace(); } } public static void invokeTestMethod(CaseServiceStub stub) { try { CaseServiceStub.Test request = new CaseServiceStub.Test(); CaseServiceStub.TestResponse response = stub.test(request); System.out.println("Test method says: " + response.get_return().getId()); } catch (java.rmi.RemoteException e) { e.printStackTrace(); } } } 对象期间，不要忘记更改WS url。在执行此类之后的结果中，您必须得到以下输出：

    CaseServiceStub

    希望这会帮助人们执行你的例子：）
