忽略Apache Axis 1.4中的意外元素的任何解决方法？ [英] Any workaround for ignoring unexpected elements in Apache Axis 1.4?

问题描述

在Apache AXIS忽略/跳过其他元素之前询问了此问题在2012年为Apache Axis 2解析时，Axis 1.4还没有解决方法吗？

The problem was asked before "Apache AXIS Ignore/Skip additional element while parsing" in 2012 for Apache Axis 2. Is there no workaround yet for Axis 1.4?

问题定义

例如;

1 - 我们有一个soap响应定义（'ResponseGetCustomerInfo'）在我们的wsdl开发时[使用 Axis 1.4 ]：

1- We have a soap response definition('ResponseGetCustomerInfo') in our wsdl while development[with Axis 1.4]:

...
  <xs:element name="ResponseGetCustomerInfo">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="ns1:CustomerID"/>
        <xs:element ref="ns1:CustomerUsername"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="CustomerID" type="xs:integer"/>
  <xs:element name="CustomerUsername" type="xs:string"/>
...

2 - 很高兴见到这一点当我们得到这样的结果时，响应是可解析的：

2- Is good to see that response is parsable when we get like this:

<?xml version="1.0" encoding="utf-8" ?> 
<soap:Envelope 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <ResponseGetCustomerInfo xmlns="http://tempUri.org/">
            <CustomerID>1</CustomerID>
            <CustomerUsername>raki</CustomerUsername>
        </ResponseGetCustomerInfo>
    </soap:Body>
</soap:Envelope>

3 - 一段时间后，我们的服务提供商更改了服务响应，为响应添加新的输出字段，我们不知道何时或为何;

3- After some time, our service provider changed the service response and adds new output fields to response and we don't know when or why;

<?xml version="1.0" encoding="utf-8" ?> 
<soap:Envelope 
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <ResponseGetCustomerInfo xmlns="http://tempUri.org/">
            <CustomerID>1</CustomerID>
            <CustomerUsername>raki</CustomerUsername>
            <CustomerName>Raki</CustomerName>
            <CustomerSurname>Bandao</CustomerSurname>
        </ResponseGetCustomerInfo>
    </soap:Body>
</soap:Envelope>

4 - 新响应理论上与旧版本兼容，因为没有删除或更改的字段。但是Axis无法解析响应：

4- New response theoretically compatible with older version because of no field neither deleted nor changed. But Axis can not parse the response:

"SAXException: Invalid Element ... "

我不想更新wsdl并再次重新生成Web服务客户端 。那么，有没有办法在响应中跳过意外的[新添加的]元素？或者任何解决方法？

I don't want to update wsdl and regenerate web service client again. So, Is there any way to skip "Unexpected[newly added] elements" in the response? or any workaround?

我正在尝试很多方法，但还找不到任何解决方案。

I am trying many ways, but could not find any solution yet.

推荐答案

由于供应商写这些服务，我们总是经历这个地狱。

We always go through this hell due to bad vendors writing these services.

所以，不幸的是，没有办法使用 WSDL2JAVA ，但有一个解决方法，你至少会重新生成一次存根：

So, unfortunately, there's no way out using parameters for WSDL2JAVA, BUT there is a workaround, you'll to re-generate stubs at least once:

1. 替换 xs：sequence with xs：all 。这允许以任何顺序返回元素，并且有助于修复很多情况，以及生成的存根代码，这使得步骤更容易


2. 对不起，但是对于每个响应bean，你从生成的代码（例如ResponseGetCustomerInfo.java）进入它的类，而不是这个：

1. Replace xs:sequence with xs:all. This allows elements to be returned in any order, and helps fix a lot of cases, as well as generated stub code which makes it easier for step
2. Sorry, but you for each response bean, you go into its class from the generated code (such as ResponseGetCustomerInfo.java), and instead of this:

while(!reader.isStartElement() && !reader.isEndElement())
   reader.next();

if(reader.isStartElement())
// A start element we are not expecting indicates a trailing invalid
// property
throw new org.apache.axis2.databinding.ADBException("Unexpected subelement " + reader.getLocalName());

有这个：

while(!reader.isStartElement() && !reader.isEndElement())
   reader.next();

// if(reader.isStartElement())
// A start element we are not expecting indicates a trailing invalid
// property

// The below is commented, to prevent unexpected result parameters from causing an exception
// (As well as the condition above is removed)
//  throw new org.apache.axis2.databinding.ADBException("Unexpected subelement " + reader.getLocalName());

它已经过测试，至少比没有解决方案更好。

It's tested and works at least better than no solution.
