JAX WS WebService 实现仅使用 XSD

Question

我有一个现有的 SOAP 客户端，它根据该 XSD 描述发送 SOAP 消息。我的 Web 服务接受调用，但我的项目列表为空。

如果我将 WebMethod 声明更改为

 @WebMethod
public Integer transferPalletRecords2(@WebParam(name = "arg0") List<Item> items) 

然后我收到 1 个包含所有 NULL 字段的项目。

DEBUG got [{RESERVED3=null, RESERVED2=null, RESERVED1=null, WAREHOUSENUM=null, LINENUM=null, QUANTITY=null, SHELFLIFE=null, RESERVED5=null, RESERVED4=null, INDICATOR=null, NAME=null, HUIDENT=null, UOM=null, DLV_NO=null, COUNTRYOFORIGIN=null, CITY=null, BATCH=null, MATNR=null, EAN13=null}] items!

任何建议出了什么问题？

Answer 1

问题解决了。我已经使用SOAPUI为我的WSDL生成SOAP请求。解决方案是：

    @WebMethod
public Integer transferPalletRecords2(PalletRecord2Array palRec) {
    try {
        System.out("Got " + palRec.getItems().size() + " items!");
    } catch (Exception e) {
        e.printStackTrace();
    }
    return 0;
}
// PalletRecord XML Struktur
@XmlRootElement(name = "arg0")
@XmlAccessorType(XmlAccessType.FIELD)
public static class PalletRecord2Array {
    @XmlElement(name = "item", required = true)
    protected List<Item> items;
    public List<Item> getItems() {
        if (items == null) {
            items = new ArrayList<>();
        }
        return items;
    }
}
public static class Item {
...
}

Answer 2

您能否也列出客户端代码？大多数情况下，当您收到空列表时，这是因为根元素名称和命名空间不匹配，因此请确保它们相同。

查找问题并纠正问题的最简单方法是生成 Web 服务的 WSDL，并从 SOAP 请求程序（如 SoapUI）获取模板请求，一旦成功，请尝试在客户端复制相同的 SOAP 信封内容
