用spring+axis调用自己写的一个测试webservice接口报错，代码如下

Question

接口代码
```public interface TestWebService {

public String getWgceaUrl(String jsonString)throws Exception;

}

实现代码

public class TestWebServiceImpl implements TestWebService{

    @Override
    public String getWgceaUrl(String jsonString) throws Exception {
        System.out.print("测试");
        return "1111111";
    }
}

```整合类
/**
 * 用于axis1与Spring进行整合
 */
public class IntegrationService extends ServletEndpointSupport {


    private ApplicationContext applicationContext;


    private TestWebService testWebService;

    @Override
    protected void onInit() throws ServiceException {
        // 初始化Spirng 配置
        applicationContext = super.getApplicationContext();

        testWebService = (TestWebService) applicationContext.getBean("testWebService");


    }

    /**
     *
     * @Description: 接口
     * @param
     * @return
     * @throws Exception
     */


    public String getWgceaUrl(String jsonString) throws Exception {
        return String.valueOf(testWebService.getWgceaUrl(jsonString));

    }
```package cn.dreamit.p1001.webservice;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

import javax.xml.namespace.QName;
import java.net.URL;

测试类如下
public class test {

    private String nameSpaceUri = "http://192.168.0.18:8080/DreamWeb/services/testWebService";
    //private String nameSpaceUri = "http://www.ntrl.gov.cn/services/WebService";
    private String wsdlUrl = nameSpaceUri + "?wsdl";

    private Service service=null;
    private Call call=null;

    public final void init() throws Exception {
        // 创建调用对象
        service = new Service();
        call = (Call) service.createCall();

        // 调用 远程方法
        call.setOperationName(new QName(nameSpaceUri, "getWgceaUrl"));
        // 设置URL
        call.setTargetEndpointAddress(new URL(wsdlUrl));
    }



    public final void testGet() throws Exception {



        // 执行远程调用，同时获得返回值
        String r = (String) call.invoke(new Object[] {"11"});

        System.out.println("jsonStrings=" + r);


    }


    public static void main(String[] args) {

        test test = new test();
        try {
            test.init();
            test.testGet();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}
wsdl配置如下
