webservice 接口用java中的axis调用，java编程传递一个参数String[]给网络接口为啥报错

Posted 2023-03-09

要传递的是一个复杂类型，wsdl说明如下
- <wsdl:types>
- <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://202.105.212.146:8080/jboss-net/services/SendSMS">
<import namespace="http://schemas.xmlsoap.org/soap/encoding/" />
- <complexType name="ArrayOf_xsd_string">
- <complexContent>
- <restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]" />
</restriction>
</complexContent>
</complexType>
</schema>
</wsdl:types>
直接传String abc[]进去会返回异常java.lang.String cannot be cast to [Ljava.lang.String请问如何解决

参考技术A 这个牵扯到数组序列化问题，前几天让我郁闷了好久。

最后是把数组表示为string,然后传入的。

2种情况
1）数组序列化的时候因为服务器端没有序列方法，所以不能正常解析为数组参数；
2）序列化后所有的参数都为null..追问

请问可以让我看看你的代码，数组如何表示为string嘛？

追答

/**
* Mehtod to convert MNCDModel to a string to avoid array serialzation
* convertMNCDModelToStr
* @param model
* @return
* String
*/
public static String convertMNCDModelToStr(MajAAPS4MNCDModel model)

StringBuilder sb = new StringBuilder("[");
//Note: KEEP all field name UPPERCASE, in server side we MUST use equalsIgnoreCase() for safety
sb.append("START=").append(model.getStart());
sb.append(",");
sb.append("OFFSET=").append(model.getOffset());
sb.append(",");
sb.append("INQUIRYIDENTIFICATION=").append(model.getInquiryIdentification());
sb.append(",");
sb.append("APPLIACTIONNAME=").append(model.getAppliactionName());
sb.append(",");
sb.append("COUNTRYCODE=").append(model.getCountryCode());
sb.append(",");

我的数组里面封装的是对象，对象之间用[]分割，对象成员之间用,分割。。

数组序列化，就我那2天搜寻的结果是不可能实现的。所以可以考虑xml封装，或者橡 我 一样用string....

参考技术B 大概是这么回事，你是直接把数组的内存地址传过去了，你看看这个schema被marshall出来的java类都有些什么属性，那个属性不见得是个数组。你用JAXB来做吧。 参考技术C import java.io.*;

// 创建传输路径和参数

// 创建调用
Call call = new Call ();
call.setSOAPTransport(st);
call.setSOAPMappingRegistry (smr);

call.setTargetObjectURI ("");

call.setParams(params);

try

catch (SOAPException e)
System.err.println("Caught SOAPException (" + e.getFaultCode () + "): " + e.getMessage ());
return;


// 检查返回值
if (resp != null && !resp.generatedFault())
Parameter ret = resp.getReturnValue();
Object value = ret.getValue();

System.out.println ("Answer--> " + value);

else
Fault fault = resp.getFault ();
