Question

我正在尝试使用wsimport工具使用远程Web服务。它生成必要的客户端代码。在那里我发现方法的返回类型是用户使用xml复杂类型定义的。如何在我的java代码中使用这种复杂类型。这是我尝试的代码

import net.restfulwebservices.servicecontracts._2008._01.WeatherForecastService;
import net.restfulwebservices.servicecontracts._2008._01.IWeatherForecastService;
import com.microsoft.schemas._2003._10.serialization.arrays.ArrayOfstring;
public class WeatherForecastClient 
{ 
    public static void main(String args[])throws     net.restfulwebservices.servicecontracts._2008._01.IWeatherForecastServiceGetCitiesByCountryDefaultFaultContractFaultFaultMessage
    {
        try
        {
            WeatherForecastService wf=new WeatherForecastService();
            IWeatherForecastService iw=wf. getBasicHttpBindingIWeatherForecastService();
            ArrayOfstring as=new ArrayOfstring();
            as=iw.getCitiesByCountry("US");
            System.out.println(as);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

在此ArrayOfstring中是用户定义的类型。我找到了一个名为ArrayOfString的文件，其中包含以下代码。

    package com.microsoft.schemas._2003._10.serialization.arrays;

import java.util.ArrayList;
    import java.util.List;
    import javax.xml.bind.annotation.XmlAccessType;
    import javax.xml.bind.annotation.XmlAccessorType;
    import javax.xml.bind.annotation.XmlElement;
    import javax.xml.bind.annotation.XmlType;
    /**

    *       &lt;/sequence>
    *     &lt;/restriction>
    *   &lt;/complexContent>
    * &lt;/complexType>
    * </pre>
    * 
    * 
    */
    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "ArrayOfstring", propOrder = {
    "string"
    })
    public class ArrayOfstring {

    @XmlElement(nillable = true)
    protected List<String> string;

    /**
     * Gets the value of the string property.
     * 
     * <p>
     * This accessor method returns a reference to the live list,

     * 
     * 
     * <p>
     * Objects of the following type(s) are allowed in the list
     * {@link String }
     * 
     * 
     */
    public List<String> getString() {
        if (string == null) {
            string = new ArrayList<String>();
        }
        return this.string;
    }

当我执行此代码时，我得到以下异常

Answer 1

某些JAXB版本不支持在XSD中使用相同的元素名称和类型名称。

你应该有两个不同的元素和类型名称。

     <xs:schema elementFormDefault="qualified" targetNamespace="http://schemas.microsoft.com/2003/10/Serialization/Arrays">   
 <xs:complexType name="ArrayOfstring">
 <xs:sequence>
 <xs:element minOccurs="0" maxOccurs="unbounded" name="string" nillable="true" type="xs:string"/>
 </xs:sequence>
 </xs:complexType><xs:element name="ArrayOfstring" nillable="true" type="tns:ArrayOfstring"/>
 </xs:schema>

在上面的XSD中，复杂类型名称和元素类型名称都是“ArrayOfstring”。它可能会导致上述异常。请尝试通过更改XSD来生成Web服务客户端，如下所示。

    <xs:schema elementFormDefault="qualified" targetNamespace="http://schemas.microsoft.com/2003/10/Serialization/Arrays">   
 <xs:complexType name="ArrayOfstringtype">
 <xs:sequence>
 <xs:element minOccurs="0" maxOccurs="unbounded" name="string" nillable="true" type="xs:string"/>
 </xs:sequence>
 </xs:complexType><xs:element name="ArrayOfstring" nillable="true" type="tns:ArrayOfstringtype"/>
 </xs:schema>

还需要更改所有其他XSD文件。

如何在java代码中使用WSDL文件中的用户定义数据类型？
